摘要:
 动态源路由协议( DSR)是为移动自组织网络设计的路由协议，性能较优，但是DSR协议中存在路由不稳定、时延大以及能量不平衡等问题。针对DSR的这些不足，通过对DSR协议的研究分析，提出了一种基于权重、链路反馈和均衡能量的DSR改进型路由协议( DSR-I)。在满足权重的路径查找中选择能量高的节点充当中继，在数据包发送的过程中低能量的节点反馈能量状态，源端主动断开旧链路，从而变更路径，并采用NS2平台对DSR和DSR-I进行了仿真实验和性能分析。实验结果表明，改进后的DSR-I路由协议比较明显地改进了原DSR路由协议的性能。
Abstract:
 The DSR is a protocol designed for Ad hoc network,which possesses good performance. But it has problems including instable routing,long delay and unbalanced energy. Aimed at these shortages of DSR,through the research and analysis to DSR,an improved rou-ting protocol is proposed based on weight,link feedback and equilibrium energy. The main idea is that nodes with higher energy are se-lected to act as a repeater in the path of meeting the weight and nodes with lower energy are used to feed back energy state in the process of data packets transmission. The source disconnects actively with the old link,thus changing the path. The NS2 platform is used to make a simulation experiments and performance analysis between DSR-I and DSR. These simulation results show that the improved DSR-I protocol promotes the performance obviously compared with the original DSR.
