摘要:

针对传统入侵检测机制不能及时发现捕获节点的问题,提出一种基于捕获概率预测的安全路由协议.该协议将网络划分为多个虚拟网格,同时利用地理位置信息和入侵检测信息建立网格被捕获概率的预测模型,并计算网格和节点的被捕获概率,从而在分组路由过程中绕过未被发现的被捕获节点.理论分析和仿真结果表明,该协议能够有效避免选择被捕获的网格作为中继网格,减少网络中被捕获信息的数量,提高数据成功传输率.

关键词: 无线传感器网络, 安全, 路由协议, 捕获概率, 预测, 中继网格

Abstract:

In wireless sensor networks, the traditional intrusion detection can not detect the compromised nodes immediately. In this paper, we propose a secure routing protocol (Secure Relay Grid Routing Protocol) based on probability prediction to solve this problem. In the protocol, the network is divided into different small grids. Utilizing the geographic information and intrusion detection information, the proposed protocol is designed with a routing metric which is based on a mathematical prediction model. The routing metric could guarantee that the message detours those compromised grids that have not been detected by the intrusion detection. Theoretical analysis and OPNET simulation results show that the proposed protocol can provide a high delivery ratio and decrease the number of the compromised packets.

Key words: wireless sensor network, security, routing protocol, compromised probability, prediction, relay grid
