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 networks, the task of routing protocols is to establish the best base station and relay path between the source node and the destination node to alleviate the cell overloading problem.This paper proposes a low-blocking routing protocol, which uses DCSP channel Allocation algorithm, taking into account the interference received in each link and allocating no interference channel in the routing process at the same time, thus reducing the call blocking rate of users and increasing the throughput of the network.The experimental results show that compared with the traditional cellular network Can alleviate 81% call rate, obviously improved the system performance.
