Patients health data is very sensitive and the access to individuals health data should be strictly restricted. However, many data consumers need to use the aggregated health data. For example, the insurance companies needs to use this data to setup the premium A single-hop wireless sensor network for distributed detection has been considered in the majority of the existing literature. However, a wireless sensor network for an event detection application with cheap and short range sensors is likely to be a multihop network. Here we
