Scalability of Network Size on Genetic Zone Routing Protocol for MANETs

This paper reports the studies related to scalability of network size on our newly proposed routing protocol, genetic zone routing protocol (GZRP) for mobile ad hoc networks (MANETs). This protocol applies genetic algorithms (GA) to zone routing protocol (ZRP) for finding a limited set of multiple alternative routes to the destinations, in order to provide load balancing and fault tolerance during node/link failure by using the routing database available with the border nodes. There are some scalability studies on ZRP based on various environmental factors like packet delivery ratio (PDR), total overhead and delay by varying the mobility of the nodes in an ad hoc network. This paper produces the results of studies related scalability of a network with GZRP, by varying the number of nodes.
