Collaborative Sensing Using Sensors of Uncoordinated Mobility

Abstract— Wireless sensor networks are useful for monitoring physical parameters and detecting objects or substances in an area. Most ongoing research consider the use of either fixedly deployed stationary sensors or sensors on mobile platforms traversing controlled paths, which incur substantial costs in either equipments or coordination efforts. In this paper, we consider a different sensing model using uncoordinated mobile nodes whose mobility is not directed for any specific sensing activity. Instead, a node independently observes a cross section of the field along its own path. The limited observation of a node can be greatly extended via information exchange among collaborating nodes coming across each other. In this model, the inherently noisy nature of mobile measurements, incomplete scope of individual node observations, different sensing objectives, and collaboration policies must be addressed. The paper proposes a design framework for uncoordinated mobile sensing and a ...
