Using Fuzzy Method for Event-Driven Top-k Query in Multi-microenvironments Sensor Networks

Fuzzy method provides tools to handle imprecise and uncertain data in relevant, robust and interpretable ways. In this paper, we highlight the multi-microenvironments in sensor network and propose a novel event-driven approximate top-k query solution based on fuzzy method. Firstly, membership function of fuzzy method is introduced to describe the global… (More)
