The authors illustrate the effectiveness of using mobile sinks to obtain potential energy savings for the sensors during data dissemination in wireless sensor networks. The entire wireless sensor network is divided into two layers: the resource-constrained sensor nodes forming the bottom layer and a mobile ad hoc network of resource-rich sink nodes forming the top layer. Each sink node is assigned a particular cluster of sensors to monitor and collect data. A sink node moves to the vicinity of the sensor nodes (within a few hops) to collect data.
