Implementation and analysis of enhancement in opportunistic network using NS2

Abstract

Opportunistic network is a new class of wireless network. This network is based on store-carry-forward mechanism. An architecture and functionality are different from another wireless network such as wireless sensor network or mobile ad hoc network. Unlike mobile ad hoc network opportunistic network do not need end to end path between source and destination nodes for providing communication between them. In this paper, methodology for enhancement in opportunistic network is proposed and implement by using network simulation. Multi-hop relay technique and Virtual-ID used together to enhance the performance of opportunistic network and at last performance of opportunistic network is analyzed by using three different cases in opportunistic network
