摘要: In this paper, we propose a multi-band multi-channel adaptation algorithm to enhance the performance of single-hop mobile ad hoc networks (MANETs) running IEEE802.11 standard. The takes into consideration medium contention, coverage range and obstacle penetration in selecting both operating band channel within selected band. Applying algorithm, MANET with its usual highly-dynamic behavior, terms mobility number active stations, seeks better environment according real-time practiced surrounding environment. operates independently on each without any type coordination other competing networks. Simulations are performed demonstrate proposed algorithm. obtained results show feasibility enhancing over fixed allocation strategies
