Wireless Sensor Networks are made up of small sensor nodes with sensing capability. These sensor nodes have limited power supply, computational capability and storage. Due to constrained energy source in wireless sensor nodes, the design and implementation of energy efficient protocols is one of the most important challenge in Wireless Sensor Networks. Mobility of sink in wireless sensor networks brings new challenges in the form sink location maintenance, continuous data delivery, avoiding/reducing detour problem but reduces the hotspot problem. In this paper, the authors propose an Energy-Efficient strategy for Grid-based Data Dissemination supporting Mobile sinks (EEGDD) in wireless sensor networks which is more energy efficient in data dissemination to the mobile sink.
