Research on GEAR with Network Coding

In the traditional routing model of Wireless Sensor Networks (WSN), intermediate nodes can store and forward messages sent by other nodes. Existing research shows that using network coding in WSN can improve network throughput and communication performance, and reduce node energy consumption. Based on the above points, this paper mainly improves the stage of the spread of interest messages in the target area in the GEAR protocol, introduces network coding to improve the process, and proposes a new network coding-based wireless sensor network routing protocol NC-GEAR (Network Coding-GEAR). According to the simulation result, the NC-GEAR protocol has better performance than GEAR. Specifically, it improves the network throughput and the performance of communication, and cut down the sensor nodes energy consumption.
