There exist a lot of medium access control (MAC) protocols for wireless sensor networks. However, they consider mainly energy efficiency rather than latency which is important in delay sensitive mobile sensor networks. Therefore, a new MAC protocol called MS-MAC is proposed suitable to both stationary and mobile sensor networks. MS-MAC uses an adaptive frame structure improved for well known protocol S-MAC to overcome the performance problems caused by the packets latency in the mobile environment. The selection of monitor nodes and periodic scheduling of synchronization packets are used to predict the speed of mobile nodes, which can save the energy consumption and minimize latencies. Our studies show that under static scenarios, the MS-MAC behavior similar with MS-MAC. However, MS-MAC can increase the network throughput and reduce the latency significantly without more energy loss in comparison with S-MAC in mobile environment.
