The wireless sensor network (WSN) is autonomous network that can establish with low cost. The integration of WSN and mobile cellular network (MCN) can provide a solution for base station communicate with the dead spot of MCN. In this paper, we present an optimal gateway selection mechanism to select the best gateway as the bridge of integrate WSN and MCN. To improve the overall network performance, we consider both WSN and MCN's parameter, number of hops between the gateway node and sensor node, the gateway load and the distance between the base station and gateway node, to achieve the best gateway selection. Simulation results with OMNeT++ shows that our scheme can enhance performance of packet delivery ratio (PDR), the average end-to-end packet delivery latency and throughput.
