Abstract
The exponentially demand of Quality of Service
(QoS) communication has made wireless
communication as an inevitable technologies.
Amongst major at hand technologies, Wireless
Sensor Network (WSN) has been found a potential
solution to meet major real-world requirements,
including monitoring and control, surveillance,
healthcare, traffic surveillance and defence systems.
Facilitating QoS demands, energy-efficiency and
secure communication has always been an open
research area for academia-industries. The lack of
security not only forces network to undergo
compromised situation but also makes it energy
exhaustive. On the other hand, providing delay
resilient, energy-efficient, higher throughout and
secure communication makes WSN robust and
efficient. Recently, the use of cryptographic
techniques has played vital role towards energy
efficient and secure communication. However,
enabling robust solution with optimal security
techniques in conjunction with improved routin
