Analysis and Design of a MAC Protocol for Wireless Sensor Networks with Periodic Monitoring Applications

In this paper, we present a new medium access control (MAC) protocol for wireless sensor networks with periodic monitoring applications. In particular, we design a listensleep time schedule for sensor nodes, and we propose a path establishment algorithm for route selection. To evaluate the performance of the proposed protocol, we conduct detailed analysis and simulations. Numerical results show that, compared to existing MAC protocols, our new protocol can significantly reduce energy consumption, average packet delay, and packet loss due to collisions.
