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

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