—This paper addresses the problem of providing congestion-management for a shared wireless sensor networkbased target tracking system. In many large-scale wireless sensor network target tracking scenarios (e.g., a surveillance system for tracking vehicles in urban environments), multiple targets may converge within close proximity of each other. Such scenarios may cause network congestion as nearby sensors attempt to concurrently send updates to a data aggregation point (e.g., base station). We consider the case in which this problem is further complicated by two factors. First, such a large-scale sensor network may very well be deployed to serve multiple target tracking applications with different and dynamic priorities and interests in different (types of) targets. Second, each application will most likely place a different premium on the timeliness of the target information (principally defined by some quality metric) they receive. All the above challenges introduce formidable cha...
