Wireless Sensor Networks (WSNs) are applied in environmental monitoring, military surveillance, etc., whereas these applications focuses on providing security for sensed data and the nodes are available for a long time. Hence, we propose DEAVD protocol for secure data exchange with limited usage of energy. The DEAVD protocol compresses data to reduces the energy consumption and implements an energy efficient encryption and decryption technique using voronoi diagram paradigm. Thus, there is an improvement in the proposed protocol with respect to security due to the concept adapted during data encryption and aggregation.

Wireless Personal Area Network is widely used in day to day life. It might be a static or dynamic environment. As the density of the nodes increases it becomes difficult to handle the situation. The need of multiple sensor node technology in a desired environment without congestion is required. The use of autonomic network provides one such solution. The autonomicity combines the local automate and address agnostic features that controls the congestion resulting in improved throughput, fault tolerance and also with unicast and multicast packets delivery. The algorithm LA based ANA in a Bluetooth based dynamic environment provide 20% increase in throughput compared with LACAS based Wireless Sensor Network. The LA based ANA leads with 10% lesser fault tolerance levels and extended unicast and multi-cast packet delivery.
