Abstract:

Mobile Communication is the present trend in the world of networking. Ad-hoc Networks is a specialized area of research in this field. Wireless mobile ad-hoc networks are networks without any physical connections. In these networks there is no fixed topology due to the mobility of nodes, interference, mulitpath propagation and path loss. Hence a dynamic routing protocol is needed for these networks to function properly. Wireless ad-hoc networks have gained a lot of importance in wireless communications. Wireless communication is established by nodes acting as routers and transferring packets from one to another in ad-hoc networks. Routing in these networks is highly complex due to moving nodes and hence many protocols have been developed. The purpose of this paper is to study, understand, analyze and discuss two wireless ad-hoc routing protocols DSDV and AODV where the first one is a proactive protocol and depends on routing tables that are maintained at each node. The other one is a reactive protocol that finds a route to a destination on demand, whenever communication is needed. Taking the bandwidth, throughput and packet loss into consideration, in both DSDV and AODV routing protocols, DSDV is best suitable for only smaller networks and AODV is suitable for general Ad-hoc networks.
