Particle Swarm Optimization and Dempster Shafer Approach to Achieve Internet of Things Context Fusion Using Quality of Context

Abstract

Context fusion is a very important aspect in a system that has to adequately simplify a required task in achieving context awareness in the Internet of things (IoT

A Multisource Situation Information Fusion Method Based on Dynamic Evidence Combination

“…As an indeterminate reasoning theory [24], evidence theory was first proposed by Dempster and later improved by Shafer [12]. Evidence theory is an extension of probability theory.…”

“…As stipulated by evidence theory, m(ϕ) � 0; however, when the conflict is too large, the probability of the null set ϕ during the evidence combination process is not always equal to 0, which may lead to unreasonable results. is is the classic Zadeh paradox [24]. erefore, when evidence theory is used to solve the fusion problem with highly conflicting data sources, the accuracy of the fusion results may be poor.…”
