提出了一种以能量为中心、基于事件驱动,适用于传感网的部分网络编码方案,满足部分节点参与网络编码情况下的高效率、低功耗信息传输.该方案根据传感网中节点的异构性和事件驱动方式的不同,将编码节点分成业务编码节点和能力编码节点,增加了网络编码的鲁棒性,提高了网络编码的效率.仿真结果表明,该方案在能耗、网络吞吐量以及传输延迟方面较传统网络编码方案更优越. An energy-centric event-driven partial network coding scheme for sensor networks is proposed to meet the high-efficiency and low-power consumption of information transmission when some nodes are involved in network coding. According to the scheme of nodes The heterogeneity and event-driven approach, the coding nodes are divided into service coding nodes and capacity coding nodes, which increases the robustness of network coding and improves the efficiency of network coding.The simulation results show that the proposed scheme has better performance in energy consumption, Throughput and transmission delay more superior than the traditional network coding scheme.
