Broadcasting in Sensor Networks: The Role of Local Information
Abstract— Flooding based strategies are conventionally employed to perform querying and broadcasting in sensor networks. These schemes have low hop-delays of Θ( 1 M(n) ) to reac...

Anti-jam distributed MIMO decoding using wireless sensor networks
Consider a set of sensors that wish to consent on the message broadcasted by a multi-antenna transmitter in the presence of white-noise jamming. The jammer’s interference introd...
