基于无线传感器网络的SPIN路由协议改进方法

Methods of improving SPIN routing protocols based on wireless sensor networks

重点讨论了SPIN协议,并提出了一种改进的SPIN协议——M—SPIN。该协议在SPIN基础上加入安全机制,以保证消息的完整性和正确性,主要采用的是消息认证码(MAC),但用户也可根据需要选择数字签名等其他安全机制。并将广播改为多播,在ADV消息中加入目标节点列表。并对M—SPIN协议在节点的能量消耗和网络安全性方面进行了分析,结果表明:M—SPIN协议不仅提高了安全性,还平衡了节点的能量消耗,延长了网络的生命周期。

The agreement focuses on the SPIN protocol and M-SPIN an improved SPIN protocol： on the basis of SPIN, the security mecbanisms is added to the protocol to ensure the integrity and accuracy of information. The message authentication code（MAC） is mainly used,but users may also need to select a digital signature and other security mechanisms. And broadcast is changed into multicast. A list of target nodes are added into ADV message. M-SPIN protocol in node＇ s energy consumption and networks security is analyzed. Results show that M-SPIN protocol not only can improve security, but also balance the node energy consumption, extend the life cycle of the networks.
