A performance analysis and comparison of various routing protocols in MANET

Mobile Ad hoc networks (MANET) are characterized by wireless connectivity, continuous changing topology, distributed operation and ease of deployment. The data is being transmitted from source node to destination through multiple intermediate nodes ie., in a multi-hop fashion. Each node has a particular range in which the transmission takes places. When a packet is being transmitted they move from one range to the other range in the network where this may lead to packet loss due to link failure and dynamic changing nature. There are many traditional routing protocols which may prevent from this data loss, but they all are susceptible to the node mobility. Here the traditional protocols are being compared with the geographic routing protocols in terms of packet delivery ratio and transmission delay.
