摘要
无线传感反应网络由传感节点和反应节点组成,传感节点将监测到的数据发送到反应节点时,通常采用单反应节点传输模型或多反应节点传输模型。针对最近为提高系统容错能力而提出的一种新的多反应节点多传感节点模型,提出了传感节点发送数据到反应节点的基于组播的新算法。实验证明这种算法可以有效地降低数据传输能耗,从而在提高网络容错能力的同时,改善系统的能量有效性。
Wireless Sensor and Actor Networks is composed of sensors and actors. When sensors send the collected data to actors, Single-Actor model or Multi-Actor model is usually used. A fault-tolerant model named Multi-Actuator/Multi-Sensor is proposed recently, for which a new algrithm based on multicast for sensors sending data to actors is presented. Simulations show that the new algrithm can save energy effectively, which means it can improve the energy efficiency of the network while keeping its tolerence to fault.
