The Effect of Network Topology on Geographic Routing Performance in Localized Networks

In this paper, we examine the role network topology play in the geographic routing decision and its performance. Much of the work carried out on geographic routing in current decade to navigate data in localized networks. In ideal environment, it has been verified to provide significant performance improvement over stringently address-centric routing approaches. Geographic routing protocol’s great benefit is its dependence only on information of the forwarding node’s immediate neighbors. The global view required is negligible and reliant on the density of nodes in the localized network, not the network size or number of destination nodes in the network. Our work is distinguished from most previous studies of geographic routing in this we consider the degree of on intermediate nodes in a path chosen by routing decision process, not just the network density. We examine several geographic properties including the possibility of deciding specific geographic path along a specific topology and effect of degree of a node in a path. Our analysis shows that routing performance depends on the network topology, and tends to be better when path traverse from medium node degree path.
