摘要

网络编码可以提高无线网络的传输性能。使用传统全网编码的网络节点必须等待其他数据包的到来进行编码，这增加了网络延迟。本文提出了ORPNC (Opportunistic Routing based on Partial Network Coding)协议，该协议将部分网络编码与机会路由相结合，以降低网络编码延迟，提高网络稳定性。同时，设计了一种新的转发策略——ETXEC，在设计转发候选集时，根据当前链路状态和节点剩余能量选择转发节点。仿真结果表明，该方法可使网络延迟降低约25%。采用ETXEC转发策略可以很好地平衡网络节点的能耗，进一步提高网络的稳定性。

A New Opportunistic Routing Mechanism Based on Partial Network Coding

The network coding could improve the wireless network transmission performance. The network nodes using the traditional full network coding have to wait the arrival of other data packets for coding, which increase the network delay. This paper proposed the ORPNC (Opportunistic Routing based on Partial Network Coding) protocol, which combining partial network coding with opportunistic routing to decrease the network coding delays and improve the network stability. Meanwhile, a new forwarding strategy -- ETXEC is designed, and the forwarding node is selected according to current link status and node residual energy during designing candidate set for forwarding. The simulation results show that network delay could be reduced by about 25%. The energy consumption of network node could be well balanced through using ETXEC forwarding strategy, and the network stability could be further improved.
