Packet Forwarding in Common Sink Multi-Domain Wireless Sensor Networks Using Non-Cooperative Game

Abstract

Multi-domain wireless sensor networks (WSNs) are sensor networks belonging to different network authorities coexisting in the same area. As such networks may be deployed in hostile environments, resource sharing between different sensor networks may necessary to prolong the network lifetime. However, with their limited power supply, sensor nodes may act selfishly by declining to cooperate to conserve their own energy. This paper is focused on how to determine packet forwarding strategies decisions which are beneficial to all networks under constrained resources in multi-domain WSNs. This paper proposes a non-cooperative game algorithm in a packet forwarding game in non-cooperative multi-domain WSNs. The objective is to achieve the best mutual strategy between two multi-domain WSNs. Our results show that the proposed method outperforms the non-game theoretic approach which uses pure cooperative and non-cooperative AODV routing algorithms, in terms of successful packet delivery ratio, network lifetime, and fairness in terms of difference in energy consumption in each domain.
