Game Theory-Based Energy Efficient Routing in Opportunistic Networks

This paper proposes a novel optimized routing protocol called Game Theory-based Energy Efficient Routing (GTEER) in Opportunistic Networks that uses game theory for selecting the best possible next hop to forward data packets efficiently. In this protocol, the best strategy for the selection of the energy efficient next hop is dependent upon a non-zero sum cooperative game of two players considering the context information, energy, and successful deliveries of the corresponding node from the destination as vital attributes in framing the game. Simulation results are provided, showing that the proposed protocol GTEER performed better than the benchmark protocols E-EDR, E-ATDTN, and GT-ACR in terms of delivery ratio, average latency and average residual energy by using the haggle-infocomm-2006 real data trace.
