Abstract: In this survey paper, various challenges to wireless sensor networks are considered and Clustering as a solution to one of them has been introduced. The wireless sensor network is divided into clusters in order to reduce energy consumption as well as to increase coverage area to larger extent. The various clustering schemes with different parameters and in different environments such as static and mobile are discussed. The fuzzy approach in cluster head selection has overcome uncertainty of wireless sensor network at different levels

Abstract: 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, we 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. This strategy is based upon permanent virtual grid structure and disseminates data from source to sink using optimal path with minimum path delay. This strategy sends query/data announcements across the certain axis only for
