摘要
研究如何提高无线传感器节点系统的可生存性。在无线传感器网络节点系统TinyOS基础上,从外部攻击和内部错误2个方面考虑改进其生存性,设计一种简单实用的入侵检测与恢复机制,改进其调度机制为支持容错的实时调度策略。仿真实验表明,改进后的系统增强了可生存性,具有较高的能量效率。
This paper analyses how to strengthen the survivability of Wireless Sensor Network(WSN) operating system. Based on TinyOS, it considers improving their survivability in two aspect: external attack and internal fault. A simple and practical intrusion detection and recovery mechanisms is designed, which improves its schedule to support the fault-tolerant real-time schedule strategy. Simulation experiment shows that the improved system enhances its survivability, and has a high energy efficiency.
