SDJS: The Duck Hunter Problem in Wireless Sensor Networks

Synchronous Distributed Jam Signalling (SDJS) is a new transmission scheme targeted to highly mobile and ad hoc wireless systems. It is based on the synchronous, parallel and superimposing emission of jam signal on the physical layer. SDJS is intended to be implemented as a feature on top of existing standards. It enables those system with the ability to fast estimate statistical parameters. This paper presents how to use SDJS to estimate the parameter number of devices in a mobile wireless ad hoc network. This new approach can increase the speed of the estimation by a factor of 1000. The whole process is also independent of the number of nodes involved.
