A major challenge affecting the performance of Wireless Sensor Networks (WSNs) comes from the unbalanced traffic over different parts of networks. High delay in transmitting information from one node to another is the prime reason behind unbalanced energy consumption .delay has continuous nature; even if two nodes are placed in bounded area, there is an infinite number of possible values for delay between them. A natural solution to reduce the delay is to have the data collector that will collect the information from all the nodes but in large network single data collector would not work efficiently; so the authors propose solution to this problem is to have multiple mobile data collectors so that the load is distributed evenly among all nodes.
