چکیده

Data collection from seabed has recently attracted considerable attention. The need to sense the underwaterworld drives the development of underwater sensor networks (UWSNs). Autonomous underwater vehicles (AUVs) areincreasingly used as UWSNs in underwater missions. A convenient application of AUVs is underwater surveillance. Insuch operations, AUVs uniformly spread throughout a harbor entry or around a target object to detect any hostile orunexpected underwater intrusions. In this research, a completely decentralized three-dimensional deployment controlalgorithm for AUVs is proposed. The goal is to achieve the desired configuration and coverage to surveillance a targetobject on the seabed. The algorithm enables AUVs to autonomously decide on and adjust their speed and directionbased on the information collected from their neighbors. Each AUV selects the best movement at each step byindependently executing a genetic algorithm (GA). In the fitness function, the global average neighborhood degree isused as the upper limit of the number of neighbors of each AUV. Experimental results show that limiting number ofneighbors for each AUV can lead to a larger covered target area around object

اطلاعات بیشتر در مورد COI

COI مخفف عبارت CIVILICA Object Identifier به معنی شناسه سیویلیکا برای اسناد است. COI کدی است که مطابق محل انتشار، به مقالات کنفرانسها و ژورنالهای داخل کشور به هنگام نمایه سازی بر روی پایگاه استنادی سیویلیکا اختصاص می یابد.

کد COI به مفهوم کد ملی اسناد نمایه شده در سیویلیکا است و کدی یکتا و ثابت است و به همین دلیل همواره قابلیت استناد و پیگیری دارد.
