Abstract
Wireless Sensor Network(WSN) is a new kind of measuring and controlling network system. Since simulation resolves the difficulties in large-scale WSN physical systems build-up, it has become an important means for WSN R&D work. In this paper, a WSN simulation system is developed based on a universal hierarchical architecture. And in terms of WSN features, an improved MAC protocol, namely P-ACK MAC, is proposed based on IEEE802.11 protocol. On our simulation platform, simulation experiments adopted three kinds of WSN route protocols and two kinds of performance evaluation criteria. Simulation results show that the performance of the proposed MAC protocol is better.
