Have You Also Seen That? Collaborative Alert Assessment in Ad Hoc Participatory Sensing

摘要

Due to their flexibility and immediacy, participatory sensing systems based on ad hoc networks have become a valuable source of proximity-based information about events and incidents in the city. However, easy contribution may result in the transmission of larges amount of data, some of them being duplicate or not relevant. We have proved that collaboratively filtering the information to be disseminated improves network efficiency while maintaining the system effectiveness.
