一种新型的无线传感器网络覆盖算法
A New Type of Coverage Algorithm in Wireless Sensor Networks
摘要
Abstract
The sensor node distribution usually has randomness and intensity in the wireless sensor network, how to effectively control nodes coverage and save energy is an important issue of the wireless sensor network. Then,proposing a coverage algorithm for wireless sensor networks has been proposed based on the dyadic wavelet transform. Network coverage optimization was turned into a model of a discrete signal, using the wavelet modulus maxima theory to solve the extreme points of this signal. Simulated the experiment results through Matlab, and analyzed the impact of the each parameters on the experimental results,the redundant nodes in the completely covered network can be effectively removed under the condition of the proposed algorithm. The minimum number of nodes can be saved more than 66% , which reduces the wireless sensor network energy and cost,and verifies the algorithm has advantages.关键词
