Coverage control based effective jamming strategy for wireless networks

A group of mobile jammers is tasked with disrupting the overall communication of a static radio network. The jammers are assumed to have limited jamming capabilities, such that the jamming effect is constrained to a disk area around the jammer. Radios within the jamming zone will be disrupted and the jamming intensity depends on the relative distance between the radio and the jammer. To disrupt the communication network, a dynamic coverage control based jamming strategy is developed, where the jammers coordinate their motion and cooperatively guarantee that every radio in the network is accumulatively disrupted up to a desired jamming level over time. It is further assumed that each jammer has a limited communication capability. Two jammers can only share jamming information when they stay within a certain distance. To ensure consistent jamming coordination, motion control laws are developed for jammers to perform effective jamming while preserving network connectivity among jammers. An appealing feature of the current work is the use of mobile jammers to dynamically disrupt the overall communication network, which enables cooperative jamming over large scale networks by using a limited number of mobile jammers.
