N2 - In wireless sensor networks with mobile sensors, frequent link failures caused by node mobility generate wasteful retransmissions, resulting in increased energy consumption and decreased network performance. In this paper we propose a new link management protocol called M-MAC that can dynamically measure and predict the link quality. Based on the projected link status information each node may drop, relay, or selectively forward a packet, avoiding unnecessary retransmissions. Our simulation results show that M-MAC can effectively reduce the per-node energy consumption by as much as 25.8% while improving the network performance compared to a traditional sensor network MAC protocol in the case of both low and high mobility scenarios.
