A Survey of Routing Protocols AODV in Mobile Ad Hoc Networks

The Mobile Ad-hoc Networks (MANETs) is an network without any pre-existing infrastructure or the aid of any centralized administration. The topology of this network keeps on changing as the nodes move randomly. There are so many protocols used for such networks. One protocol is Adhoc On Demand Distance Vector (AODV) routing protocol. AODV decrease the routing overhead and hence enhancing the performance of the network. Routing in MANET is a critical task due to extremely dynamic environment. Several routing protocols have been proposed for ad hoc networks and best among them are DSR, AODV. Mobile nodes can establish network connections anytime. Routing protocols are needed for communication in Ad hoc networks, where it targets for efficient and timely delivery of the messages. The main goal of such type of network is to provide rapid communication, computing and deployment. Each mobile node in Ad Hoc network is capable of routing packets and assists surrounding nodes to do so. In this dynamically changing topology environment the role of routing protocols are very important. This paper provides an overview of AODV protocol by presenting their characteristics, functionality, benefits and limitations and then analyzes security requirements for ad hoc routing protocols.
