Original scientific paperIn wireless sensor networks, efficient communication is the ultimate goal of a wireless medium access control (MAC) protocol.Concurrent transmission is one of the main ways to solve the issues of traditional MAC protocols with low throughput and accumulated delay in wireless sensor networks with highload and intensive nodes.In this paper, a novel concurrent transmission MAC protocol is proposed that exploits channel capture allowing successful concurrent transmission to ensure effective communication.We use a power control algorithm based on non-cooperative game theory with incomplete information to achieve multiple link concurrent transmission on the same channel.Moreover, the Bayesian-Nash equilibrium theorem is introduced to determine its existence and uniqueness proof.Simulation results show that the protocol we proposed can perform well in an interference environment for concurrent data transmission.Significantly, the network throughput is improved and the data propagation delays are reduced therefore saving energy.Also, since we use the channel resources effectively, spatial reusing efficiency is improved significantly.
