Abstract:

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.
