The Challenges for Context – Oriented Data Accumulation with Privacy Preserving in Wireless Sensor Networks

Wireless Sensor Networks (WSNs) plays a vital role in our everyday lives. In WSNs the data are to be sensed between one node to another set of nodes in the network for the purpose of achieving transmission. At the time of transmitting sensed data in the Wireless Networks it may utilize large amount of energy (like power consumption, payload, etc.) for any operation. Accumulating data plays vital role in conserving energy in the network framed using wireless sensors. Accumulation of the data is a procedure which was mainly designed to minimize the overhead in the communication as well as control energy utilization in sensor nodes during the process of data collection. A data aggregation protocol plays a firewall for protecting data among the elements of wireless transmission. Enhancing the lifetime of wireless networks is a challenging issue. In this paper we analyse the challenges for privacy preserving in protocols of data accumulation (aggregation). initially the accumulation protocol is based on various metrics like energy consumption, accuracy of data, authentication of data and confidentiality of data. Here we also identify various resolvable issues for enhancing quality of preserving privacy in aggregation protocols.
