A Trust Application in Participatory Sensing: Elder Reintegration

摘要

Whatever traveling abroad or within their's own cities, everyone aims at optimizing their route in terms of time, distance or even sightseeing. But, finding the best path in a crowded city is very challenging in terms of continuous changing traffic conditions, road maintenance state and user needs. Most people axe busy with daily-basis activities, but elders tend to walk more and, therefore, they develop expertise on the traffic state and/or the presence of works going on the roads. Our driving ides is to take advantage of the knowledge that elderly can gather. For example, a tourist can go sightseeing in a new city by using an elder's advice. When decisions are based on information collected from other individual, trust management is a key problem. Also in our case, we must deal with the problem of the freshness of the elder's information and the trustworthiness of their knowledge. Our work presents a solution for this issue by proposing a new trust management in participatory sensing for path optimization using cloud based services.
