摘　　要：在温室、救灾等环境监测过程中,无线传感器网络会因频繁发生自然故障和遭受恶意攻击而引起网络可生存性问题,针对这一问题提出了一种可自维护的具有抗毁性的拓扑控制算法。仿真结果表明,该算法能够简单有效地构建并维护容错拓扑结构,在节点失效时保证网络拓扑容错抗毁,使得无线传感器网络具有可生存的能力。During environment monitoring such as greenhouse and disaster relief, the natural fault and the malicious attack occur frequently in the wireless sensor network. It is going to raise some problems of network survivability. To solve this problem, a self-maintainable topology control algorithm with invulnerability is proposed. The simulation resuhs show that the algorithm is simple, and can effectively construct and maintain the fault tolerant topology. When node failure appears, this algorithm ensures the fault tolerance and the invulnerability of network topology. It makes wireless sensor networks have the survivable ability.
