SUN Ze-yu, GAO Chun-ling, CAO Yang-jie, et al. An Enhance Event-Driven Strategy Coverage Holes Compensation Algorithms[J]. 2016,(3):22-25. DOI: 10.13756/j.gtxyj.2016.03.008.
Coverage holes phenomena is appeared in the process of random deployment of wireless sensor network systems.This paper presents a probabilistic model by means of event-driven policy coverage holes compensation method(Coverage Holes Compensation Algorithms Based on Event-Driven Strategy
CHCAEDS).Firstly
the characteristics of random deployment are verified and the representation of random deployment is given.Then
based on the probabilistic method
the desired coverage and the number of nodes within the surveillance area are solved in order to achieve maximum coverage area using minimum number of nodes.Finally
the simulation result show that the CHCAEDS can improvethe network life cycle and the algorithm running time by 12.59% and 10.82% when comparing with other algorithms.
