Weeraddana, D. MWalgama, K. SKulasekere, E. C2022-02-022022-02-022013-07-27https://rda.sliit.lk/handle/123456789/910A framework to estimate the state of dynamically varying environment where data are generated from heterogeneous sources possessing partial knowledge about the environment is presented. This is entirely derived within Dempster-Shafer and Evidence Filtering frameworks. The belief about the current state is expressed as belief and plausibility functions. An addition to Single Input Single Output Evidence Filter, Multiple Input Single Output Evidence Filtering approach is introduced. Variety of applications such as situational estimation of an emergency environment can be developed within the framework successfully. Fire propagation scenario is used to justify the proposed framework, simulation results are presented.enDempster-Shafer Belief theoryEvidence FilteringEvidence FilteringEvidence FusionSensor ModalitiesWireless Sensor NetworksArticle
