AODV,DSR and GRP. | ISSN:2249-5789 Prof.Santosh Deshpande, International Journal of Computer Science & Communication Networks,Vol 6(3),175-180 Behavioural Analysis of MANET Protocol under Specific Conditions Prof.Santosh Deshpande H.O.D Computer Department MES IMCC, Pune (SPPU University) sarvesh_santosh2003@yahoo.com Abstract The paper presents the results of a detailed packet-level simulation comparing three multi-hop wireless ad hoc network routing protocols under the load of different probability distributions, that cover a range of design choices having different protocol viz. AODV,DSR and GRP. We have extended the OPNET network simulator to accurately model the MAC and physical-layer behaviour of the IEEE 802.11 wireless LAN standard, including a realistic wireless transmission channel model. Simulation of 100 mobile nodes has been carried out and the performance optimization is determined.

Introduction Ad-hoc wireless network is that network where no communication is present, in such network; each mobile node operates not only as a host but also as router. Mobile nodes in the network may not be within range of each other, communication of these nodes perform by discovering “multi-hop” paths through the network to other nodes. This type of network is some time called infrastructure less network [1]. Some examples of the possible uses of ad hoc networking are students using laptop computers to participate in an interactive lecture, business associates sharing information during a meeting, soldiers relaying information for situational awareness on the battlefield [2, 3]. Many different protocols have been proposed to solve the multi hop routing problem in ad hoc networks, each based on different assumptions and intuitions. Mobile Ad hoc Networks (MANETs)[1] are an emerging technology that allows establishing an instant
