Distributed Dynamic Channel Assignment in Military Ad Hoc Networks within the MAENA Project: New Algorithm and High Fidelity Simulation Results

In this paper, we present results coming from the Multi bAnd Efficient Networks for Ad hoc communications (MAENA) project. We present a distributed dynamic channel assignment (DDCA) algorithm for military clustered ad hoc networks that has been designed during the project. To design the proposed algorithm, we start from an existing algorithm called greedy based dynamic channel assignment (GBDCA). We first identify the main drawbacks of this algorithm, and then we propose modifications to alleviate these drawbacks yielding the proposed GBDCA++ solution. We also explain how to implement the GBDCA++ algorithm in a military waveform developed in the MAENA project. Finally, we show the superiority of GBDCA++ over GBDCA by providing high fidelity simulation results obtained using the simulator developed within the framework of the MAENA project.
