摘要： 考虑到无线网络中广播特性、丢包特性、节点移动等对网络性能的影响，提出一种针对大规模无线多跳网络的鱼眼机会路由协议。在机会路由的基础上加入鱼眼技术，减少链路状态更新信息。在鱼眼路由表中加入链路传输概率，得到转发列表，并且简化机会路由协议的报文头结构，从而实现高效的数据传输。NS2仿真结果表明，该协议能降低网络端到端延时，提高网络吞吐量。

Abstract: This paper proposes a fisheye opportunistic routing protocol for large-scale wireless multi-hop network, which takes the effect of broadcasting, packet loss and mobile node into account. The protocol brings in fisheye technology to decrease the number of link state update message. It adds in link transmission probability to get forwarder list and simplify the header of opportunistic routing protocol, achieves the data transmission efficiently, and makes full use of the respective advantage of opportunistic routing and fisheye state routing. The performance of network can be improved, and the protocol supports large-scale multi-hop wireless mobile network better. NS2 simulation result shows that the protocol can decrease the end-to-end network delay and enhance the throughput.
