Secure and Energy Efficient Routing Protocol in Wireless Sensor Network: A Survey

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 an 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 routing model is an open research area. With this motivation, in this paper some of the key literatures discussing cryptographic techniques and routing approaches for energy efficient and secure communication for WSN. This study revealed that the use of a time and computation efficient cryptography system in conjunction with enhanced routing protocol can ensure secure and energy-efficient communication over WSNs.
