Abstract

In current era due to the fast growth in telecommunication technologies, there is a drastic expansion in the number of subscribers using communication network. In mobile ad hoc network, mobility of nodes and obstacles present in terrain affect a lot the efficiency of the mobile network. When there is change in mobility and presence of obstacles in terrain, link between neighbour nodes breaks very often as a result of which the network performance degrades. Many authors have investigated the performance degradation of network due to the change in mobility taking various reactive protocols but they have considered presence of obstacles. This paper gives a thorough investigation of the performance degradation due to the variation in mobility of nodes in presence of irregular-sized obstacles in terrain at different traffic conditions. The performance of two popular reactive routing protocols AODV and DSR is compared on basis of different network parameters.
