摘　　要：在多跳蜂窝网络中,路由协议的任务是建立源节点和目的节点之间的最佳的基站、中继站路径,缓解小区的超载问题.本研究提出一种低阻塞路由协议,该协议以DCSP信道分配算法为基础,考虑了在各环节中所受到的干扰,在路由过程中同时分配无干扰信道,从而降低用户呼叫阻塞率,提高网络的吞吐量.实验结果表明,该协议相比传统蜂窝网能够缓解81%呼叫率,明显提升了系统性能.In Multi-hop Cellular Network （ MCN ）, the reliable routing which selects the shortest path between source nodes and desti- nation nodes via RSBSs, to divert the problem of an overload area. In this paper, we propose a low blocking routing protocol, which based on DCSP algorithm. Our works is to reduce call blocking rate while considers interferences of each hop and ensures quality of each link to increase network throughput. The experimental results show that, ours can reduce 81% call blocking rate, compared to traditional cellular network and obviously improve system performances.
