Resistance to extended IEMI by physical/correlated wireless random and non-random networks

Ad-hoc wireless networks are comprised of mobile communications nodes (users and supporting relays) that typically have just enough radiating power to reach adjacent nodes, and in particular must operate in non-planned electromagnetic environments where propagation and EMC conditions are precarious and inter-node communications capabilities are highly variable. Nodal locations evolve from necessity, convenience, and circumstance. In a previous paper, one of us made the case that these ad-hoc wireless networks could be classified as random networks. It was suggested that system level performance metrics based on the random aspects of inter-node communications (viz. percolation threshold and nodal connectivity distribution) be added to the traditional metrics of electromagnetic field strength and shielding to assess network performance. The effects of IEMI are then evaluated not only on a local interference basis but also on a network-wide basis. In this paper, we (1) derive the connectivity degree distribution of nodes for a particular model of an ad-hoc wireless network and assess its susceptibility to attack when IEMI is uniformly distributed throughout the network, and (2) examine the consequences of non-homogeneous IEMI by renormalizing the (statistical) wireless network to the scale imposed by the extended IEMI footprint
