A Comprehensive Performance Analysis of MANET Protocols

Mobile ad hoc networks are characterized by wireless connectivity, continuous changing topology, distributed operations, and ease of deployment. We compare two reactive routing protocols, dynamic source routing (DSR) and ad hoc on-demand distance-vector routing (AODV), and one proactive destination-sequenced distance-vector routing (DSDV) protocol by using Manhattan mobility model. We have analyzed the performance of protocols by varying network load, mobility, and type of traffic (CBR, TCP). A detailed simulation has been done using NS2. We consider packet delivery fraction, routing overhead, normalized routing load (NRL), and end-end delay as metrics for performance analysis of these protocols.
