能量有效的无线传感器网络可信路由协议

如何更有效地利用节点有限的资源是无线传感器网络研究的热点之一。提出的能量有效的可信路由协议(energy efficient reliable routing protocol, EERRP),采用了一种能量均衡策略，使网络中的能量均衡消耗，将网络生命周期最大化。同时,EERRP引入了信誉评价机制，通过节点在数据传输过程中对其他节点行为的监测以及信誉传播，使数据在通信过程中能够尽可能地避开问题节点到达目的节点，达到可信数据传输的目的。通过在NS仿真平台对EERRP进行测试与验证，并将其与传统路由协议进行比较，证明EERRP在网络能量有效性和数据可信传输方面具有明显优势。

Energy efficient routing reliable protocols in WSNs

The recent interest in sensor networks has led to a number of routing schemes that use the limited resources available at sensor nodes more efficiently. A novel energy efficient wireless sensor network routing protocol called EERRP is proposed. This routing protocol uses a lightweight strategy, which makes the network consumption of energy balanced. And the routing protocol adopts an evaluation mechanism of credibility, by means of which the nodes monitor other nodes’ action and spread of the credibility in data transmission, as a result, the data can reach the destination nodes smoothly without the interference of malicious nodes. Through the NS simulation platform for testing and verification, EERRP, which is compared with traditional routing protocols, proves the obvious advantages on the effectiveness and reliability of data transmission and energy saving.
