Performance Evaluation of The SYN-MAC Protocol in Multihop Wireless Networks

Due to the complexity of throughput analysis in wireless networks with multiple collision domains, how to model system performance in multihop wireless networks remains challenging. Based on our previous proposed synchronized medium access control (SYN-MAC) protocol and its performance analysis in single collision domain, we propose an effective analytic model with low computational complexity for evaluating the performance of SYN-MAC in multihop wireless networks. Our simulation results verify the numerical analysis very well, showing the effectiveness of our proposed approach. Furthermore, an enhanced SYN-MAC protocol is presented to optimize its channel efficiency and throughput in multihop wireless networks. Our simulation results show the SYN-MAC protocol significantly outperforms IEEE 802.11 in all scenarios, regardless of the payload sizes, network sizes, or nodal densities.
