چکیده

Wireless Sensor Network is a specific kind of Wireless Networks that has been taken into consideration by various sciences in recent years. These Networks could be used inenvironmental monitoring, agricultural science, industry, medical science, etc. position of sink could be static or mobile.Communication between nodes could be multi-hop or in clustering-mode and sending data to sink could be done singlestep or multi-hop. A crucial issue of these networks is theirlimited lifetime due to using batteries with limited energy. As a consequence, various protocols have been proposed consideringenergy efficiency. In this paper, MDCA algorithm is proposed to integrate data using some mobile sinks. In proposed method,managing movement of sinks in network environment is done, led to load and energy regulation. We tried to improve network efficiency by determining an appropriate rout for sinksmovement. Duty cycling mechanism is used for decreasing energy consumption. In this way, a percent of sensor nodes are going tosleep mode (in the network's runtime). Routing algorithm is considered based on distance and remaining energy of sensornode, so more appropriate routs are selected during runtime. Simulation and evaluation results show that our proposed method performs better than other methods that have been mentioned here.

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.
