An Effective Approach for Mitigating Reactive Jamming Attacks in Wireless Sensor Networks

Wireless Sensor Network (WSN) is an emerging technology for various applications public sector, private sector and military. It formed by a large number of networked sensing nodes. It contains of many sensor devices to cooperatively monitor selected target locations and communicate with base stations. Due to the different requirements of large-scale and realtime data processing in WSNs, provide high security is very critical in many sensor network regions and applications also against attacks especially jamming attacks. Moreover, to overcome the problems in existing methods against reactive jamming attacks, we propose an effective approach for identifying the trigger nodes and mitigating jamming attacks in WSN, whose transmission activate any active jammers. In this paper, we examine two main parts, identification or localization of trigger nodes and avoid active jammers in transmission. First, of all, to design better routing protocol to identification of triggers nodes, so it is easily identify the active jammers. Secondly, we propose an effective approach to avoid reactive jamming attacks. The theoretical analysis and experimental results show that our solution performs well in terms of time management and different complexities means messages, which in turn provides a good approach to defend reactive jamming attacks.
