【Abstract】 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 results 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.更多还原
