Energy Efficient Routing and Secure Data Communication in Wireless Sensor Networks

About 70% of the total energy is dissipated for data transmission in most of the Wireless Sensor Network (WSN) applications. Hence, energy aware routing protocols are required to find efficient route in order to prolong the network lifetime in WSNs. Security is another critical issue in WSNs and a number of security schemes are developed to provide security services. However, these algorithms have their own weaknesses, such as vulnerable to chosen-plaintext attack, brute force attack and computational complexity. In this study, we propose an energy aware heuristic-based routing protocol and a lightweight cryptographic scheme to provide energy efficiency and security in WSNs. Our further aim is to design secure multi-path routing and DNA-based cryptographic schemes for WSNs.
