基于节点信任度的三维覆盖算法
Three dimensional coverage algorithm based on node trust degree
摘要
Abstract
Aiming at the problem of security and coverage of nodes in wireless sensor network,this paper presented a three di-mensional coverage algorithm based on node trust degree(NTA3D).The algorithm based on the idea of virtual force,grid divi-sion and node trust,introduced the grid joint trust.The area was divided into grids,and the attractive source was placed at the center of each grid.The attractive source could compute the joint trust degree of the grid based on the active node in the grid. All nodes were scheduled based on joint trust.After the scheduling was finished,the work nodes were redeployed according to the size and direction of the virtual force.The simulation results confirm that the algorithm can improve the coverage efficiency and reduce the network energy consumption under the premise of ensuring the security.关键词
