Wireless sensor networks are the networks which can sense, analyze and then communicate the data. The data collection at sensor nodes consumes a lot of energy but sensor nodes are energy constraints. Most of the WSN architectures consist of stationary nodes which are heavily deployed over a sensing area. In recent times, several WSN architectures based on Mobile Elements (MEs) have been proposed. The usage of Mobile elements resulted in a newer mode in order to minimize and provide a energy consumption in Wireless Sensor Networks (WSN). Most of them develop mobility to deal with the problem of data collection in WSNs.
