Study of node raliability in a participatory sensor network

Abstract

Participatory sensor network is a network where participants or nodes use mobile phones or social network and feed data to detect an event. Data is gathered and analyzed to an event. As data gathering is open to many participants, one of the major challenges is to identify if the reported observations are true or false. It becomes more challenging when node or participant's reliability is un- known or even the probability of event to be true is unknown. In our research, we study this challenge and observe that applying evolutionary method, event detection becomes more reliable. We call this approach Population Based Reli- ability Estimation (PBRE). In this research project we do simulation study and our experimental results show that PBRE performs better than other reliability estimation method in our de ned environment.
