Abstract
How to accurately locate and track mobile jammers in Multi-Hop Wireless Network (MHWN) is critical to restore network service and promote the quality of service of MHWN since its performance may severally be influenced by jamming attacks. Current research mainly focuses on object tracking in cooperative network configuration where the tracked object actively provides useful information to the tracking applications. However, this cooperative assumption will not hold for the jammer localization problem since jamming attacks can seriously affect network transmission. Moreover, the mobility property of the jammers makes current static jammer localization methods fail in this case. Therefore, in order to bridge this gap, a distributed mobile jammer tracking scheme is put forward in this paper which contains four steps, i.e., monitoring node selection, jamming signal measurement and result collection, jammer localization and monitoring node handover. In order to evaluate the effectiveness of the proposed scheme, a series of simulation experiments have been conducted. Experimental results have validated the effectiveness of the proposed scheme.
