Network-level HEMP effect evaluation on fully-connected wireless networks

Wireless communication networks are very crucial for any operations of all sectors of modern society such as commercial mobile communication or military communication. High-altitude electromagnetic pulse (HEMP) leads severe threats to the survivability and robustness of communication network. Due to the high complexity and hard proven properties of large-scale networks, network-level HEMP effect evaluation (NHEE) is a hard mission. Hence, based on a simplified and typical wireless network called fully-connected network (FCN), this paper proposes a network-level HEMP effect evaluation scheme. It firstly introduces the system survival probability and network topology as model input parameters into the evaluation procedure, and then defines performance metrics such as traffic capacity, normalized network connectivity degree, network throughput to accurately evaluate the network performance after HEMP attack. The model and simulation are based on the graph, probability theory and the OPNET software. It reveals that, FCN network performance will behave a different degree of performance reduction with different system-level survival probability caused by HEMP attack. The result indicates that the proposed scheme is capable of evaluating HEMP effects on wireless network.
