Wireless sensor network link reliability optimization algorithm based on artificial bee colony algorithm

Abstract

The invention discloses a wireless sensor network link reliability optimization algorithm based on an artificial bee colony algorithm. The method specifically comprises the following steps: dividing a monitored three-dimensional area into 1 * w * h pixel points to form a point set Ra, deploying |S| sensor nodes in a network in total so as to meet the coverage and communication requirements of the network, wherein S is an overall sensor node set, and is a set of a preset sensor node set Sp and a supplementary sensor node set Sa, namely S = SpUSa; and deploying the preset sensor node set Sp on the point set Ra in a network. The invention has the beneficial effects that compared with a previous process of seeking the link reliability through an artificial bee colony algorithm, the problem of the overall network link reliability under the three-dimensional angle of the wireless sensor network is solved, and the adaptive value of a food source is introduced to adjust the search process; and the global optimization and local optimization capabilities of the solution are stronger, so the coverage problem of the wireless sensor network is solved more effectively.
