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.
