Digital Filter Design For Jamming Mitigation In 802.15.4 Communication, Bruce Debruhl, Patrick Tague

Jamming attackers can dramatically increase attack efficiency and stealth by randomly or periodically cycling the jamming transmission on and off, attacks respectively known as random and periodic jamming. In this paper, we analyze the impact of such attacks on the IEEE 802.15.4 communication protocol, commonly used in wireless sensor networking applications, and show that the cycling behavior introduces a narrow spectral component into the received signal. We propose the inclusion of a digital filter at the receiver side to effectively eliminate this spectral component, and we discuss the benefits involved in this filter design. We evaluate the impacts of random …

Multiple-path source routing protocols allow a data source node to distribute the total traffic among available paths. In this article, we consider the problem of jamming-aware source routing in which the source node performs traffic allocation based on empirical jamming statistics at individual network nodes. We formulate this traffic allocation as a lossy network flow optimization problem using portfolio selection theory from financial statistics. We show that in multi-source networks, this centralized optimization problem can be solved using a distributed algorithm based on decomposition in network utility maximization (NUM). We demonstrate the network’s ability to estimate the impact of jamming …

The impact of a jamming attack on wireless communication depends on a number of physical characteristics and network protocol parameters. In particular, it depends on the relative geometries of the adversarial network of jammers and the network under attack. Hence, changes in network geometry achieved through node and jammer mobility can have significant influence on the impact of a jamming attack. In this work, we investigate the use of mobility as a tool to allow both the adversarial network and the network under attack to reconfigure their geometry in an attempt to improve attack impact and protocol performance, respectively. We …
