MAC Performance and Improvement in Mobile Wireless Sensor Networks
Bing Liu, Ke Yu, Lin Zhang, Huimin Zhang · 2007
Former Media Access Control (MAC) protocols for Wireless Sensor Networks (WSNs) are mainly for static networks. In the networks where mobile nodes exist, the performance will degrade greatly. In this paper the performance of MAC in mobile WSNs (mWSNs) is analyzed and improved algorithms are presented. Simulations validate the effects. A new MAC protocol also is presented for the scenario with more mobile nodes.
