Exploring optimised route selection strategy in tree- and mesh-based multicast routing in MANETs

Abstract

Mobile ad hoc networks are collections of mobile nodes with dynamism forming a momentary network, with no pre-existing network infrastructure or centralised administration. Disaster relief, education and armed forces are widespread situations where mobile nodes need to communicate in areas without any pre-existing infrastructure. Multicast routing protocols outperform the basic broadcast routing by giving out the resources along general links while sending information to a set of multiple destinations. As the network topology is dynamic, optimised routing protocols are needed for communication proficiency. This paper explores the intelligent Genetic Algorithm (GA)-based on-demand multicast routing protocol and GA-based multicast ad hoc on-demand distance vector protocol which improve the control overheads and packet delivery ratio in the routing messages.
