Description: Abstract—In this paper, we consider distributed estimation of
a noise-corrupted deterministic parameter in energy-constrained
wireless sensor networks from energy-distortion perspective.
Given a total energy budget allowable to be used by all sensors,
there exists a tradeoff between the subset of active sensors and
the energy used by each active sensor in order to minimize the
estimation MSE. To determine the optimal quantization bit rate
and transmission energy of each sensor, a concept of equivalent
unit-energy MSE function is introduced. Based on this
concept, an optimal energy-constrained distributed estimation
algorithm for homogeneous sensor networks and a quasi-optimal
energy-constrained distributed estimation algorithm for heterogeneous
sensor networks are proposed. Moreover, the theoretical
energy-distortion performance bound for distributed estimation
is addressed and it is shown that the proposed algorithm is
quasi-optimal within a factor 2 of the theoretical lower bound.

Description: Wireless Sensor Networks (WSN) is an emerging technology
and day by day it is attracting the attention of researchers
with its challenging characteristics and diversified application domain. The more researchers try to develop further
cost and energy efficient computing devices and algorithms
for WSN, the more challenging it becomes to fit the security
of WSN into that constrained environment. However, security is crucial to the success of applying WSN. So, familiarity
with the security aspects of WSN is essential before designing WSN system. This paper studies the security problems of
WSN based on its resource restricted design and deployment
characteristics and the security requirements for designing
a secure WSN. Also, this study documents the well known
attacks at the different layers of WSN and some counter measures against those attacks. Finally, this paper discusses on
some defensive measures of WSN giving focus on the key
management, link layer and routing security Platform: |
