Group-Mobility-Aware Spectrum Management for Future Digital Battlefields

Efficient access to spectrum is critical to maintain reliable and robust communication in military networks, especially for ground vehicles on the move. High mobility and frequent topology variations make spectrum management in battlefields challenging. In this paper, we present a decentralized, hierarchical approach to assign spectrum channels among vehicles in a fair and efficient manner. Making use of group mobility, we propose a low-complexity allocation scheme with minimum communication and computation overhead. Experimental results demonstrate that the proposed algorithm can reduce the overhead by 10+ fold with maintaining reasonable spectrum utilization
