Network Processing of PT-TOPK Queries Using Necessary Set Based Algorithm in WSN’s
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2014, Vol 3, Issue 10
Abstract
A wireless sensor Network consists of spatially dispersed self-directed sensors to monitor the environment conditions. This work supports innetwork top-k query process over uncertain data in a distributed wireless sensor network. We develop the notion of necessary Set for efficient in-network pruning of uncertain data in a distributed setting. Based on the necessary sets, we propose, necessary set-based, algorithm for in-network processing of PT-Topk queries in a two-tier hierarchical sensor network. For providing privacy proposing locked Q protocol that that prevents attackers from gaining information from both sensor collected data and sink issued queries.
