Abstract
Internet of Things (IoT) refers to uniquely identifiable objects and their virtual representations of an Internet like structures. The main
goal of the IoT is to make the sense the information of the computing device without the need of human interaction. Zigbee Wireless
sensor node is a communication protocol which is used to transmit data over long distances by passing data through the intermediate
devices to cover longer distant and provides secure networking. It can be used anywhere at any time. It requires less power to operate
and it can be implemented easily with any type of wireless generation. 4G (Fourth Generation) is the next generation of wireless
networks and it can provide fast and secure data transfer. Speed of 4G can be achieved by OFDM modulation and it will utilize most
of the existing wireless communication infrastructure. World Wide Interoperability for Microwave Access (WiMAX) is wireless
technology and it provides wireless data over long distance. WiMAX provides a media access control (MAC) and proposes the full
range of security features to secured data exchange. It transmits the data at 70 Mbps. In this paper, Zigbee Wireless sensor nodes real
time data transmission integrated with 4G Technology for long distance Secure Communication with high mobility is proposed and
analyzed using OPNET. The performance such as delay, data sent, Jitter and end-to-end delay and packet delay variation are
simulated.

1. INTRODUCTION
Two different technologies which find a swift and a massive
growth at present are Cloud Computing and the next one is In-
ternet of Things (IoT). The next era of computing will be out of
the present traditional computing, where the computers will be
able to access the data without any human interaction on the
field. Internet of Things (IoT) represents an integral part of the
future internet [1]. IoT can be realized into three paradigms as
IP (Internet Protocol) oriented (middleware), things oriented
(sensors) and semantic-oriented (knowledge) [2]. Zigbee is the
Wireless sensor standard based technology that addresses the
unique needs of most remote applications [3]. Zigbee networks
provide security using 128 bit symmetric encryption keys and
uses Direct Sequence Spread Spectrum (DSSS) [4]. It supports
for multiple network topologies such as point-to-point, point-to-
multipoint and mesh networks [5]. 4G is a technology which
supports high quality audio and video streaming end to end IP
[6]. 4G system targets peak data rates of approximately 100
Mpbs for high mobility and 1Gbps for low mobility services. It
supports bandwidth in a range of 5 to 20 MHz 4G supports both
the TDD and FDD duplexing [7]. It uses orthogonal frequency
division multiplexing (OFDM) access for LTE DL, WiMAX
UL, WiMAX DL and single carrier frequency division multiple
(SC-FDMA) access for LTE UL [8]. WiMAX is an IEEE
802.16 standard which is highly efficient and is suitable for
long range applications. WiMAX base station can offer greater
wireless coverage of about 5 miles in a line of sight transmis-
sion within the bandwidth of up to 70 Mbps [9]. Zigbee module
is a wireless sensor network (WSN) platform which is based on
the IEEE 802.15.4, 2.4 GHz standard [10]. Zigbee uses two
types of commands for communication- (i) AT commands and
(ii) API commands. Zigbee can be either used as a coordinator
or a router or an end device. It uses serial communication pro-
tocol for the transfer of data and operates at a range of 3.3V DC
[11]. The coordinator organizes the network and maintains the
routing and it responsible for initializing, maintaining and con-
trolling the network. Router communicates to the coordinators,
to other routers and to end devices. It forms network backbone
to the end device can communicate to the router and coordina-
tor but not with another end device [12]. PAN is the combina-
tion of a single coordinator, one or more routers and end devic-
es. The routers and end devices can communicate with the
coordinator within the PAN. To cover large area more number
of PAN is formed [13]. Worldwide Interoperability for Micro-
wave Access (WIMAX) is a 4G technology used to transmit the
wireless data to cover longer distances [14]. WiMAX forum
mission is to promote and certify compatibility and interopera-
bility of broadband wireless products [15]. WiMAX offers al-
ternative to the traditional wireless data transmission over the
cables and digital subscriber lines. WiMAX is based on the

_________________________________________________________________________________________
radio frequency (RF) technology called Orthogonal Frequency
Division Multiplexing (OFDM) [16]. It is an effective way for
transferring the data more than carrier width of 5MHz and be-
low the carrier width of 5MHz CDMA based 3G system is suf-
ficient [17]. WiMAX is a standard-based wireless technology
and offers high throughput broadband connections. WiMAX
provides WMAN connectivity with a speed of 70 Mbps and its
base station covers an average distance of 5 to 10 km [18]. It
provides communication path between a subscriber site and a
core network. In this paper Zigbee wireless sensor is integrated
with WiMAX technology for data transmission. Here multime-
dia transmission is considered and analyzed. The scenarios and
challenges of next generation wireless communication is dis-
cussed in [19].
The rest of the paper is organized as follows. The section II
discuss about proposed novel Zigbee and WiMAX network
Integration for IoT. In Section III Performance analysis of the
propose work is discussed. Section IV concludes the paper.
2. ZIGBEE AND WIMAX NETWORK INTEGRA-
TION
2.1 Motivation and the Proposed System
In the literature, Zigbee sensor networks are integrated through
either GSM (Globle system for Mobile) 2G or GPRS (General
Packet radio System) 2.5G for the data transmission. Here data
can be transmitted only to a shorter distance and also smaller
coverage area with more delay without any security. Here the
motivation is to integrate Zigbee sensor nodes with WiMAX
Technology to transmit multimedia data for secure transmis-
sion. In the proposed model the data can be transmitted to long-
er distance without much complexity.
Fig 1 Zigbee module integrated with 4G WiMAX
The Figure 1 shows the proposed architecture of zigbee wire-
less sensor module integrated with 4G WiMAX for global cov-
erage which is used for the application of Multimedia teleconfe-
rencing (Voice & Video). The network architecture contains
three PANs, set to PAN ID 1, 2, and 3. The network also con-
tains a mobile node, initially placed next to PAN 1, with its
PAN ID set to Auto-Assigned. The three PANs have their
transmit power configured to 2 mill watts so that their coverage
areas do not overlap. The trajectory of mobile_node_1 is confi-
gured to take the node through the coverage area of each of the
three PANs over the course of 20 minutes. Based on this trajec-
tory, it is expected that mobile_node_1 will initially join PAN 1,
then switch to PAN 2, and finally to PAN 3. This architecture is
designed to cover large area with efficient data traffic. The traf-
fic on each node except mobile_node_1 is configured as Ran-
dom destination. When they join the network, they will choose
a random node within their own PAN and send traffic to that
node for the rest of the simulation. Here mobile_node_1 is con-
figured to send traffic to its parent node. Additionally all PAN
Zigbee coordinators are interfaced through a processing Con-
troller unit (PCU). This controller is connected to WiMAX base
station (BS) through wireless access gateway (WAG). This will
act as transmitter part of the proposed architecture. The receiver
part is also consists of WiMAX-BS along with WAG where the
corresponding application server is present. Initially PAN 1
sends multimedia information with the help of Zigbee Coordi-
nator through end user which is located at the long distance to
PAN 2. Then PAN 2 and PAN 3 with the help of Controlling
unit which is connected with Zigbee Coordinator communicates
4G Base station and transmit the multimedia information to the
receiving 4G base station and finally Application servers rece-
ives the teleconferencing messages which is sent by Zigbee
sensor nodes.
3 PERFORMANCE ANALYSIS
In Performance analysis teleconferencing, data and Voice appli-
cations are analyzed for Zigbee sensor nodes along with 4G
network integration for long distance transmission to support
high mobility. In X axis, simulation time period in seconds is
taken. In Y axis corresponding parameter is taken. The simula-
tion time period taken for analysis is 2000 seconds.

The figure 2 shows that Video streaming traffic received and
sent for the proposed architecture. Here video traffic sent and
received is same. This shows that proposed architecture output
performs well. This shows there is minimum delay with large

_________________________________________________________________________________________
throughput.The Figure 3 shows that Video Packet delay varia-
tions and Packet end-to-end delay for the proposed architecture
is very less for the received video traffic of 650,000 bytes per
seconds. This also shows global coverage with minimum delay.
Since processing unit is connected to all the PAN groups, if any
one PAN group fails to transmit data, It identifies and informs
to corresponding coordinator to retransmit or otherwise the data
copy from other PAN groups can be used to transmit anywhere
at any time without waiting for long time. Hence mobile node
movement trajectory is captured and sensed by controlling unit
and transmit the stored data via 4G network. In the receiving
side again data is received through 3G/4G using application
servers with QoS (Quality of service). From figure 4, Voice
Jitter and Voice packet delay variations is also very less. Jitter
is nothing but Variation in delay. Here data is sent via all sensor
nodes. This shows proposed architecture performs well with
very less delay for large traffic. MOS (Mean Opinion Score)
value is used to judge the voice quality measurements. The typ-
ical MOS value for practical 4G network is 4. Here it is 3.9.
Voice packet delay variations are also less for the proposed ar-
chitecture. Here from this figure 5 voice traffic received is more
or less same as voice traffic sent. There is only minimum packet
loss in the architecture. The voice end-to-end delay is also very
less for the architecture. This shows proposed Zigbee sensor
Node while integrated with 4G network, performs well even for
real time voice. The figure 6 shows a Pan affiliation of a Zigbee
network. PAN Affiliation for mobile_node_1: The graph shows
mobile_node_1 joined to PAN 1 for the first 240 seconds of the
simulation. The node then briefly joins from the PAN ID 1, and
then promptly joins PAN 2. At 720 seconds, the nodes join from
PAN 2 and promptly join PAN 3. Finally It collectively sends
data to controller unit which in turn connected with 4G Wi-
MAX.
4. CONCLUSIONS
In this paper Wireless sensor Node which is coming under In-
frastructure less network, integrated with 4G Technology for
data transmission for global coverage especially for security
applications in remote areas. The main idea is to reduce the
delay of the senor nodes data transmission for large real time
multimedia traffic by transmitting through infrastructure archi-
tecture like WiMAX network. As a future work The proposed
architecture is also connected through 5G, LTE (long term evo-
lution) network as a part of next generation wireless network
technology.
