An Advanced MAC Protocol for Wireless Sensor Networks

This paper proposes a new, energy efficient medium access control (MAC) protocol for wireless sensor networks. Wireless sensor networks consist of thousands of simple nodes. Energy efficiency is primary goal in wireless sensor networks. The new protocol is suitable for low-power consumption while latency is less important. The new protocol called DMDS-MAC which is based on distributed mediation device (DMD) protocol and S-MAC protocol utilizes listening/sleep duty cycle mechanism. And it uses mediation device to synchronize the neighbor nodes temporarily. Then they can communicate each other successfully. This can decrease the cost of the nodes
