Energy Efficient, Distributed Clustering Approach for Ad Hoc Wireless Sensor Network

With the increasing growth in assorted applications for resource-limited Wireless Sensor Networks (WSN), the requirement for reliability and efficiency in security mechanisms for them has increased a lot but its implementation is a non-trivial task. Limitations in processing speed, power of battery, bandwidth and memory consisting the applicability of existing cryptography algorithms for WSNs. Ad hoc sensor networks are ad hoc networks that are characterized by decentralized structures and ad hoc deployment. Sensor networks have all the basic parameters of ad hoc networks but to different degrees for example, much lower mobility and much more stringent energy requirements. In this paper the pragmatic analysis on the energy consumption and optimization issues are underlined. This work analyzes the existing state of research and evaluates the issues in development of techniques in wireless sensor networks related to energy harvesting and optimization.
