Mobile ad hoc networks

Abstract

Cluster Based Routing Protocol (CBRP) proactively divides the nodes of the ad hoc network into a number of overlapping or disjoint clusters in a distributed manner. The number of routing overheads was significantly reduced and the path optimality was improved in a previous project. This project builds on the improved protocol to look at two important aspects of routing in MANETs a?? reliability of links and power control. A method is derived to measure the reliability of links. The average path delay is reduced by over 40%. The packet delivery ratio is increased from 99.4% to 99.82%. Building on the reliability model, power control is introduced. The average power usage is reduced from 281.84 mW (24.49 dBm) to 279.08 mW (24.46 dBm). The packet delivery ratio is improved from 94.24% for the original CBRP and 94.33% for the improved CBRP from the previous project to 95.46%.
