DVR-BASED MANET ROUTING PROTOCOLS TAXONOMY

In ad hoc network, each node is equipped with a wireless transmitter and receiver (transceiver) that is powered by a battery. Two nodes willing to communicate with each other need to be either in the direct common range of each other or should be helped by other nodes to act as routers forwarding their packets. A node in a Mobile Ad hoc Network (MANET) acts as dual role of a host and a router as well. Designing routing algorithm for MANET is a difficult job compared to designing routing algorithm for wired networks. The important challenges in routing in MANET are due to same intrinsic characteristic of MANET, like limited battery power, highly dynamic nature of network topology, limited bandwidth, asymmetric links, scalability, mobility of nodes etc. In this paper, we analyzed DVR based routing protocols aiming to find suitable path through special neighbours between hops in MANET. This paper classified various routing protocols based on DVR for MANET and compared on the characteristics (routing metrics), performance and complexity.
