Performance Analysis and Optimal Cooperative Cluster Size for Randomly
Distributed Small Cells Under Cloud RAN
Abstract:
One major advantage of cloud/centralized radio access network is the ease of
implementation of multi-cell coordination mechanisms to improve the system
spectrum efficiency (SE). Theoretically, large number of cooperative cells lead to a
higher SE; however, it may also cause significant delay due to extra channel state
information feedback and joint processing computational needs at the cloud data
center, which is likely to result in performance degradation. In order to
investigate the delay impact on the throughput gains, we divide the network into
multiple clusters of cooperative small cells and formulate a throughput
optimization problem. We model various delay factors and the sum-rate of the
network as a function of cluster size, treating it as the main optimization variable.
For our analysis, we consider both base stations’ as well as users’ geometric
locations as random variables for both linear and planar network deployments.
The output signal-to-interference-plus-noise ratio and ergodic sum-rate are
derived based on the homogenous Poisson point processing model. The sum-rate
optimization problem in terms of the cluster size is formulated and solved.
Simulation results show that the proposed analytical framework can be utilized to
accurately evaluate the performance of practical cloud-based small cell networks
employing clustered cooperation.

Computer networkParthipan Parthi

This document discusses different types of switching techniques used in internetworks. It describes circuit switching and packet switching as the two broad categories of switching. Circuit switching establishes a dedicated communications channel between two stations in three phases: establish, transfer, and disconnect. Packet switching can use either a datagram or virtual circuit approach. The datagram approach treats each packet independently by routing them from source to destination. The virtual circuit approach pre-plans a route for packets to follow from source to destination. The document also discusses IP addressing methods and different classes of IP addresses including Class A, B, C, and D. It describes an activity for students to discuss the drawbacks of each IP address class.

Various Clustering Techniques in Wireless Sensor NetworkEditor IJCATR

This document summarizes various clustering techniques used in wireless sensor networks. It describes clustering algorithms such as Low-Energy Adaptive Clustering (LEACH), Event-to-Sink Directed Clustering, K-means algorithm, Load Balanced Clustering scheme, and Weight-Based Clustering protocols. These clustering techniques aim to improve network lifetime and energy efficiency by distributing load evenly and reducing data redundancy in wireless sensor networks. The document concludes that Weight Based Clustering technique is the most efficient as it avoids selecting low energy nodes as cluster heads, but it can sometimes generate unnecessary extra cluster heads.

The document proposes a new routing protocol called Sector Tree-Based Clustering for Energy Efficient Routing Protocol (STB-EE) for wireless sensor networks. STB-EE partitions the sensor field into dynamic sectors to balance the number of nodes per cluster. Within each sector, STB-EE constructs a minimum spanning tree to connect nodes and reduce long-distance communication. STB-EE selects cluster heads based on remaining energy and distance to the base station. Simulation results show STB-EE can improve network lifespan by about 15-16% compared to other protocols.

Energy balanced improved leach routing protocol for wireless sensor networkscsandit

A proper sensor node clustering is an effective topology control that can balance energy consumption among sensor nodes and increase network scalability and life time. As the use of wireless sensor networks (WSNs) has grown enormously, the need for energy-efficient routing and data aggregation has also risen. LEACH （ Low Energy Adaptive Cluster Hierarchy ） is a hierarchical clustering protocol that provides an elegant solution for such protocols. Random clustering is the main deficiency of LEACH. In this paper an energy balanced clustering approach is proposed, in which the K-mean clustering algorithm is applied. It is centralized clustering algorithm that based on minimum energy clustering to form optimal clusters. For the candidate nodes, the location and the residual energy are used as key parameters to select the cluster head (CH). The method shows that the proposed approach outperforms LEACH in terms of energy conservation and network life time prolonging.

An automated dynamic offset for network selection in heterogeneous networksmuhammed jassim k

This document proposes an automated dynamic offset approach for network selection in heterogeneous networks. The approach uses a hierarchical Bayesian game framework where the macro cell dynamically chooses an offset for the reported channel quality to guide users to intelligently select between the macro cell and small cell networks. The model is analyzed to derive the utilities and equilibria, and is shown to optimize the global network utility while users maximize their individual utilities. A key contribution is developing a polynomial time algorithm to determine the dynamic offset value at equilibrium. Simulation results show the proposed hierarchical mechanism maintains a price of anarchy close to 1, even for a small number of users, which is better than a non-cooperative model.

Minimization of Energy Consumption using EPAR-DSR Protocol in ManetIRJET Journal

This document summarizes a research paper that proposes a new routing protocol called EPAR-DSR for minimizing energy consumption in mobile ad hoc networks (MANETs). The key points are: 1. EPAR-DSR aims to reduce energy consumption during packet transmission between nodes to extend the lifetime of battery-powered nodes in the MANET. 2. It modifies the Dynamic Source Routing (DSR) protocol to select routes based on the remaining energy of nodes as well as path length. This helps avoid overusing nodes with low battery levels. 3. Simulation results show that EPAR-DSR achieves higher throughput, longer network lifetime, and better packet delivery ratios compared to standard DSR

An Adaptive Cluster Based Routing Protocol for WSNEswar Publications

The Wireless sensor networks (WSN) consisting of a large number of sensors that are effective for gathering data in a variety of environments, as the sensor operate on battery which is of limited power. To support high scalability and better data aggregation in fixed base station communication, sensor nodes are often grouped into disjoint, non overlapping subsets called clusters. Clusters create hierarchical WSN which incorporate efficient utilization of limited resources of sensor nodes. These clusters are formed by specialized cells. Each cluster is managed by a special node called cluster head and advanced node. An algorithm for better cluster head selection based on the node energy and the distance from base station to the cluster head for the efficient transmission and to reduce energy consumption by the sensor nodes is proposed in this paper. And the same algorithm is compared with the LEACH algorithm in terms of energy consumption.

Energy balanced on demand clustering algorithm based on leach-cijwmn

The proposed algorithm aims to improve energy efficiency in wireless sensor networks. It uses a centralized k-means clustering algorithm to form clusters based on minimizing total energy. The base station calculates relevant information for each node, including total network energy, distance to neighbor nodes, and cluster assignment. Nodes then use this information to probabilistically elect cluster heads within each cluster in a distributed manner. The algorithm considers both energy levels and communication distances to select optimal cluster heads. Simulation results show the proposed algorithm outperforms LEACH-C in network lifetime, stability period, and energy efficiency.

Validation of Wireless and Mobile Network Models and Simulation Paper ReviewZunAib Ali

The document discusses approaches for validating wireless network simulations against real world experiments. It suggests comparing simulation results to emulation and measurement results over time using time-sequence plots of performance metrics. An example shows plots of a TCP connection's behavior in a simulated, emulated, and real network. While emulation curves were shifted from simulation results, the "direct emulation" approach tracked the simulation curve more closely. Comparing full event traces from simulation and experiment is also proposed but challenging to implement due to complex interactions between events. The validation approaches suggested seem appropriate for small to medium networks if modelers make suitable modeling choices.

Service description in the nfv revolution trends, challenges and a way forwardieeepondy

The telecommunications landscape is undergoing major changes with the introduction of SDN and NFV, which allow new ways of designing networks and deploying network functions. Accurately describing the services to be provided is crucial for integrating and ensuring interoperability between different NFV proposals. However, fully realizing the benefits of NFV presents unique challenges that the current service description proposals do not fully address. This paper reviews current NFV service description proposals, identifies key challenges, and proposes a straw man model for service and resource description that could guide future initiatives in addressing these challenges.
