Research on Routing Reliability in Opportunistic Networks
Yan Xue-fei · Computer Technology and Development · 2010
The appearance of plenty of intelligent devices equipped for short-range wireless communications boosts the fast rise of wireless ad hoc networks application.The opportunistic networks is one of the applications.Opportunistic networks utilize the communication opportunities arising from node movement to forward messages in a hop-by-hop way,and implement communications between nodes based on the store-carry-forward routing pattern.In this study,consider three types of non-collaborative behavior,namely free rider,supernova,and wormhole behavior,in opportunistic networks.Also evaluate the impacts of the three types of behavior on the data transmission performance of three widely used routing schemes.Simulation results of real-world traces of network mobility show that the data forwarding performance degrades signicantly as the number of non-collaborative peers,except wormholes increases.
