摘　　要：基于信息协商的传感器网络路由协议(SPIN)数据转发过于复杂、重复转发相同数据包的问题影响了SPIN协议转发时的网络吞吐量,增加了丢包率,缩短了网络的生命周期。针对以上问题,提出了一种动态路由信息协商传感器协议D-SPIN协议,其在SPIN协议基础上加入了动态路由表建立算法和验证下一跳id选择性转发策略,该方法可有效提高网络吞吐量,减少了丢包率,延长了网络时延。利用NS2仿真软件进行仿真,仿真结果表明,D-SPIN协议比SPIN协议在网络吞吐量、丢包率和网络时延等性能参数上有较大的提高。〔Abstract〕Problems of SPIN＇s （Sensor Protocol for Information via Negotiation） too complicated data forwarding and repeated forwarding of the same packet affect its performance on network throughput and increase the packet loss rate and reduce the network lifetime. To solve these problems, a SPIN protocol based on dynamic routing called D-SPIN protocol is proposed, which is based on SPIN but adds the strategies of dynamic routing table creation and algorithm and next hop id verification and selective forwarding. D-SPIN can effectively improve network throughput, decrease the packet loss rate and extend the network delay. NS 2 software is used to simulate and the results show that D-SPIN protocol has a more significant improvement in throughput, packet loss rate and the network delay than SPIN protocol.
