DEMAC: A Cluster-Based Topology Control for Ad Hoc Networks
Abhishek Majumder, Nityananda Sarma · 2010
The presence of transient network links, mobility and limited battery power of mobile nodes in MANETs poses a hefty challenge for such networks to scale and perform efficiently when subjected to varying network condition. Most of the topology control algorithms proposed have high control overhead to discover and maintain route from source to destination. They also have very high topology maintenance cost. To minimize routing overhead and topology maintenance cost CBRP (Cluster Based Routing Protocol) was developed. It performs better than other approaches in most of the cases. In this paper, an energy and mobility aware clustering approach is presented. The clustering approach is incorporated in a DSR like protocol for routing in MANET to evaluate the performance improvement gained due to clustering using proposed approach. Rate of cluster head changes, throughput of the network, delay and routing overhead is evaluated using NS2. Simulation results reveal that proposed approach has better performance in comparison with CBRP.
