Energy Efficiency S-MAC Protocol for Wireless Sensor Networks

Tóm tắt:

One of the most important constraints in traditional wireless sensor networks is the limited amount of energy available at each sensor node. In WSNs, sensors are usually equipped with capacity-unreplaceable battery sources. Therefore, optimizing an effective wireless sensor network to maximizing the lifetime of sensor node in order to minimize energy resource and maximize overall system performance becomes important. The energy consumption is mainly determined by the choice of media access mechanism. Sensor-MAC is a typical access mechanism that has drawn much attention in recent years about minimizing solution energy resource. In S-MAC, a border node is located the least of two virtual cluster, each virtual cluster has private sleep timer, listen timer, wake-up timer. Border nodes can listen more schedules than other nodes, so they need to have more energy consumption which make their power to consume faster, to affect to maintain productive purpose information, data. This paper propose a solution method about energy efficiency when nodes add its SYNC information to their list schedules which only implement one schedule later.
