Optimization problems are among the greatest challenges for emergent communication technologies, especially under conditions of multiple constraints and multicriteria optimization objectives. Metaheuristics are recognized as a powerful approach capable of optimizing the QoS of complex communication networks with challenging environments. Metaheuristic algorithms have been applied for this purpose in wireless networks, in ad-hoc and mobile networks, and in optical networks. We study specifically in this paper the AntHocNet metaheuristic dedicated to ad-hoc networks.
