An optimization coverage algorithm with controllable dynamic parameters

Abstract

The energy consumption and coverage is a fundamental problem in the field of wireless sensor networks,which is also a priority issue.Based on the isomorphism of the sensor nodes,an optimized coverage algorithm with controllable dynamic parameters（OCCDP）was presented.Firstly,it gave the solution of the largest seamless coverage probability under the joint coverage of three nodes.Secondly,it gave the solving method of the sensor nodes coverage quality expectation in monitoring area and compares to neighbor nodes coverage probability determination method.When there was a redundant coverage,it gave the process of calculation of coverage probability when any sensor node was in the condition of redundant nodes coverage.Finally,through the comparison of the simulation with other algorithms in terms of the coverage quality and the network lifetime,it can be concluded that the average performance can upgrad to 11.02% and 13.27%,which proves the effectiveness and feasibility of the algorithm.
