| 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. |
