Abstract :
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 in environmental 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 single-step or multi-hop. A crucial issue of these networks is their limited lifetime due to using batteries with limited energy. As a consequence, various protocols have been proposed considering energy 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 sinks movement. Duty cycling mechanism is used for decreasing energy consumption. In this way, a percent of sensor nodes are going to sleep mode (in the network´s runtime). Routing algorithm is considered based on distance and remaining energy of sensor node, 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.
