摘要： 在移动自组网中，负载重的节点可能会因为拥塞或较大的延迟而成为网络的瓶颈，从而导致网络性能下降。针对该问题，提出一种负载均衡的分段式路由协议。引入局部负载中心点的概念，对中心点周围区域的负载进行计算并构造虚拟环路。利用虚拟环路进行路由选择，从而避开负载中心点，实现负载均衡。模拟结果表明，该协议能使网络的负载分布更均匀，相比以前的算法有更好的吞吐率。

Abstract: In Mobile Ad hoc Networks(MANETs), the heavy-load nodes may be the network bottlenecks due to the greater congestion or delay, leading to performance degradation. Aiming at the problem, this paper proposes a Segment-by-Segment Based Load Balancing Routing(SSB-LBR) protocol in MANETs. It introduces the concept of load center, calculates the load of the nodes in the region around the load center and constructs virtual loops. It uses the virtual loops to make choice of routings to avoid the load center, realizing load balancing. Simulation results show that the proposed protocol can enable the network load more evenly distributed and have better throughout compared with the previous protocols.
