Abstract

Multi-hop wireless networks (MHWN) have emerged to be a promising cost effective paradigm for the next-generation wireless technology. However, the unique characteristics of nowadays MHWN, such as distributed and dynamic network architecture, broadcast nature of wireless medium and stringent resource constraints of wireless devices, makes it extremely attractive and vulnerable to malicious attacks. So how to ensure continuous network service becomes a critical problem especially in jammed situations. Although some research has been conducted on countering jamming attacks, few works consider jamming dynamics. In this paper, interference avoidance mechanisms are well concerned and a proactive multi-path routing mechanism based on measuring jamming dynamic is presented. In our proposed solutions, the novel mechanism defines a new metric for routing known as the degree of interference activity (IA) to represent the jamming dynamic on a node. A comprehensive simulation study is conducted to evaluate the performance of the proposed scheme. Performance results show that our solution outperforms existing ad hoc routing protocols in terms of packet delivery and average end-to-end delay in the presence of jammers.
