IMPROVING TCP PERFORMANCE OVER MOBILE AD-HOC WIRELESS NETWORKS THROUGH ROUTING PROTOCOLS

Abstract

Mobile ad hoc networks have gained a lot of attention lately as a means of providing continuous network connectivity to mobile computing devices regardless of their physical location. Recently, a large amount of research has focused on the routing protocols needed in such an environment. This work presents two routing protocols for routing in ad hoc networks, namely Dynamic Source Routing (DSR) protocol and Ad hoc On-Demand Distance Vector routing (AODV) protocol. DSR adapts quickly to routing changes when a host moves, yet requires little or no overhead when hosts move less frequently. Based on results from a packet level simulation of up to 25 mobile hosts operating in an ad hoc network, it can be concluded that protocol performs well over a variety of environmental conditions such as host density and movement rates.
