Battlefield Reconnaissance and Monitoring WSN Transport Protocol based on Network Coding

In the battlefield reconnaissance and monitoring environment, the application of Wireless Sensor Network (WSN) requires high timeliness and reliability of data transmission. To meet the battlefield demand, a transmission protocol is designed in this paper. This protocol combines network coding technology to fully play the function of node collaboration in the transmission process and use the channel broadcast characteristics. The data is transmitted in real-time and reliably through the aggregation node to the command control center, providing a real-time update database for the battlefield commander. Through theoretical and simulation analysis, this protocol can meet the requirements of the battlefield reconnaissance and monitoring environmental log, and the system can still maintain better network performance in the condition of low probability of transmission of battlefield environment.
