Optimization of Spin Protocol Combined with Network Coding

For classic wireless sensor networks (WSN), the received data is only stored and forwarded by nodes [1]. Existing research has shown that network coding can make the nodes form a store-encode-forward mode, which is a great improvement on the performance of wireless sensor networks. According to the above analysis, this paper chooses the SPIN protocol as our research object and looks for opportunities to use the network coding in the SPIN protocol when the intermediate node broadcasts the ADV message [2]. On this basis, this paper proposes a new improved routing protocol NC-SPIN based on network coding. Through simulation experiments, it can be found that the NC-SPIN routing protocol has improved throughput and communication performance and decreased energy consumption at intermediate nodes compared to the SPIN protocol.
