A Dominating Set Based Clustering Algorithm for Mobile Ad Hoc Networks
نویسندگان
چکیده
We propose a new Connected Dominating Set (CDS) based algorithm for clustering in Mobile Ad hoc Networks (MANETs). Our algorithm is based on Wu and Li’s [14] algorithm, however we provide significant modifications by considering the degrees of the nodes during marking process and also provide further heuristics to determine the color of a node in the initial phase. We describe, analyze and measure performance of this new algorithm by simulation and show that it performs better than Wu and Li’s [14] algorithm especially in the case of dense networks.

Determining Cluster-Heads in Mobile Ad-Hoc Networks Using Multi-Objective Evolutionary based Algorithm
A mobile ad-hoc network (MANET), a set of wirelessly connected sensor nodes, is a dynamic system that executes hop-by-hop routing independently with no external help of any infrastructure. Proper selection of cluster heads can increase the life time of the Ad-hoc network by decreasing the energy consumption. Although different methods have been successfully proposed by researchers to tackle...

متن کاملMaintaining weakly-connected dominating sets for clustering ad hoc networks
An ad hoc network is a multihop wireless communication network supporting mobile users. Network performance degradation is a major problem as the network becomes larger. Clustering is an approach to simplify the network structure and thus alleviate the scalability problem. One method that has been proposed to form clusters is to use weaklyconnected dominating sets [Y.P. Chen, A.L. Liestman, App...
متن کاملClustering Wireless Sensor and Wireless Ad Hoc Networks using Dominating Tree Concepts
The most important criterion for achieving the maximum performance in wirless sensor and ad-hoc networks is to clustering the nodes. Many clustering schemes have been proposed for different ad-hoc networks. In sensor networks the energy stored in the network nodes is limited and usually infeasible to recharge. The clustering schemes for these networks therefore aim at maximizing the energy effi...
