Wireless Sensor Network Mac Protocol Software Design And Simulation Testing

Wireless Sensor Network (WSN) is regarded as one of most important technology which plays vital role in everyday life. Combining with many advanced technology, this new technology provides us with ways to receive and deal with information. But its distinct characteristics calls for challenges in protocol design, network organization and operation. The paper focuses on the design of MAC system and protocol realization based on the project of WSN System, which is sponsored by ICT and SZICC.First of all, the paper introduces the overall structure of the MAC protocol using the multi-hop communication mode, to fulfill the requirement of WSN in collision avoidance, energy efficiency and scalability to the change in network, bandwidth utilization, latency, throughout and fairness. First, the improvement in the connection building time and improvement based on hypothesis makes the existing SMACS protocol suitable for the WSN. And the paper proves this statement by using the PARSEC software. Then, the SMAC protocol is designed to fulfill the consideration of energy efficiency, self-organization, multi-hop and topology mobility. It achieves good scalability and collision avoidance by utilizing a combined scheduling and contention scheme. To demonstrate the effectiveness and measure the performance of SMAC protocol, this paper implements it on the platform of NS. At last, future work is presented.The contributions of this work are therefore:1. Design the overall architecture of protocol for Wireless Sensor Network.2. Perfect the existing SMACS protocol.3. Design the test procedure for the improved SMACS protocol.4. Design the SMAC protocol.5. Design the test procedure for SMAC protocol.
