Cluster Based Controlling of Route Exploring Packets in Ad-Hoc Networks

Abstract

Route Discovery in Ad-hoc Networks is an important process that is used to find the optimal path for data transmission. This route exploring process can be either proactive or reactive depends on the nature of the routing protocol. When a routing protocol initiates a route exploring process, it uses query packets to discover the optimal path. These packets are broadcasted over the network. Since they propagate in the network even after route has been found, these packets become problem of congestion in the network. So, we have proposed a cluster based approach along with Expending Ring Search (ERS) to control these route discovery packets in these networks. In our approach, we divided the whole network into clusters to achieve the scalability of the network and used modified BERS+ to reduce the retransmission of query packets in the network. © Springer International Publishing Switzerland 2014.
