An Evidential Approach for Area Coverage in Mobile Wireless Sensor Networks

The study of coverage problem in uncertain WSN environment requires the consideration this uncertainty by taking best possible decisions, since it is impossible to explicitly represent all combinatorics produce a conditional active/passive state nodes' planning area interest, and allow reasoning on various environmental states partially known physical world. This paper addresses based Dempster-Shafer theory. authors aim ensure full while using subset connected nodes, with minimal costs number dominant nodes regardless type used deployment (random or deterministic). ensured activating single node each geographic sub-area, thus extending lifetime wireless sensor network its maximum. comparison proposed model denoted evidential approach for (EAAC) two well-known protocols recent one showed better performance slight improvement covered area.
