Abstract:
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.
