An Overview of Query-Broadcasting Techniques in Ad Hoc Networks

Abstract

This chapter presents query-broadcasting techniques used to minimize expenses of the route discovery in ad hoc networks. A broad variety of such techniques have been proposed that improved the effectiveness and efficiency in various aspects of route discovery considering time and energy. Time-to-live based broadcast is the most common controlled flooding scheme widely used in routing protocols. One category of such techniques leveraged the routing history, while other category used broadcast repealing strategy to cancel the query-broadcast after successful route discovery.

MCDM Approach to Improve the Quality of Broadcasting Technique in Wireless Ad-hoc Networks

“…There are many approaches to discover route in WANETs, most common being reactive routing with most significant disadvantage of continued propagation of query even after route had been discovered. This leads to undesirable consequences like congestion in network, broadcast storm [3]. To overcome the issue many researchers have proposed dividing the network into small and manageable request zones for intermediate nodes.…”
