| 摘 要： | 针对无线协作通信的中继选择问题和高可靠性的需求，提出了一种基于跳数限制的无线传感器网络数据传榆的自适应协作FEC差错控制机制．无线传感器网络中，在数据链路层根据FEC能效在不同数据帧长下随通信距离变化的规律，为每一个数据帧选择最佳协作跳数并建立多中继协作FEC机制；网络层根据IPv6数据包头中的跳数限制域值设定协作传输跳数并计算得到当前数据帧所经历的跳数，根据跳数自适应调整FEC参数N．数学分析表明，该机制能够自适应为每一个数据包添加较少的冗余数据同时自适应选择最佳协作传输跳数，与传统FEC相比提供了更优通信性能．

| Abstract: | The reliable delivery and relay selection of data transmission over wireless cooperative communicationi s a big challenge. This paper proposes an adaptive and cooperative forward error control mechanism, calledC FEC, based on IPv6 and hop constraint at the data link layer for wireless sensor networks. Firstly, in a WSN, ad ata transmission mechanism with multiple relays was established according to the characteristics of the energye fficiency of FEC with different communication distance. Secondly, the FEC p... |
