Gateway Selection Algorithms Based on the Influence of Nodes for Mobile Opportunistic Networks
Li Zhu · Science Technology and Engineering · 2014
In mobile opportunistic networks,suitable nodes are needed to be chosen to perform as gateways for users to obtain data from the Internet rapidly. The problem of gateway selection in mobile opportunistic networks is investigated. Two gateway selection algorithms based on the influence of nodes are proposed: LRGS and CRGS.Experiment results prove that compared with the random selection algorithm both the two algorithms can improve the network performance. When the network size is small,CRGS performs better,and it is big LRGS performs better.Both the two proposed algorithms are scalable.
