Novel extension of Binary Constraint method for automated frequency assignment: Application to military battlefield environment

Abstract

Wireless communication plays an important role in mission plan activities of various military and battlefield situations. In each of these situations, a frequency assignment problem arises with application specific characteristics. This paper presents a novel extension to binary constraint [1] method for automation of frequency assignment in battlefield scenarios. The proposed method calculates the cost function considering each node of the radio net in battlefield equally important. Two cases for calculation of cost function are considered; in the first case the average of the signal (from intra radio nodes) and interference (from inter radio nodes) is considered whereas in the second case the intra radio nodes causing minimum signal and inter radio nodes producing maximum interference are taken into consideration for cost calculation. A simulation exercise in lab environment has been done for validation of proposed methods by creating a battlefield scenario with three radio nets each consisting three-radio nodes. © Springer International Publishing Switzerland 2014.
