A social selfishness compatible routing protocol in opportunistic networks


More and more mobile devices are emerging in our lives. And the wireless applications and services based on mobile devices bring more flexible lives. However, the heavily overhead to 3G network obstacle the applications. Opportunistic Networks is an open field to settle this problem recently. It enables mobile devices to communicate in a circumstance where end-to-end connections are unavailable or unstable. Message routing and forwarding are based on nodes’ cooperation through store-carry-and-forward manner by use of short message transmission technologies such as Bluetooth or WiFi. The existing of selfishness nodes make the performance decreased heavily. In this paper, based on Prophet, we consider social selfishness compatible routing protocol (SS-Prophet) in DTNs. Simulation and experiment demonstrate that SS-Prophet obtain higher performance in selfishness circumstance.
