基于SRP算法的安全AODVjr协议

SRP Based Secured AODVjr Routing Protocol for Wireless Sensor Network

无限传感器网络由大量具有微处理能力的传感器节点组成,对物理环境参数进行各种监控。路由是无限传感网络中的一个重要问题,路由协议用于实现各种路由功能。AODVjr协议是应用最为广泛的无限传感器网络路由协议。作为AODV协议的简化,AODVjr协议省略了AODV协议中的各项优化措施,因此在节能性方面优于AODV协议。但是AODVjr协议没有在路由过程中采取安全措施,因此不能对路径信息和传送的数据提供安全保障。该文将SRP安全算法应用于AODVjr协议,提出了能够保障路径信息安全的SAODVjr协议,并给出了协议安全性的理论证明。

A wireless sensor network (WSN) is a group of spatially distributed sensor nodes that cooperatively monitor the physical or environmental conditions. Routing is an important issue in WSN and routing protocol is responsible for the routing function. AODVjr routing protocol, a simplified version of the widely used Ad hoc on-demand distance vector (AODV) routing protocol, removes the optimization strategies from the original AODV routing protocol such as HELLO message mechanism and route error message broadcasting mechanism; while inherits only the dynamic characteristic from AODV routing protocol. Due to this simplification, AODVjr outperforms AODV routing protocol in energy consumption and thereby is widely used in various WSNs.
