NLM-MAC: Lightweight Secure Data Communication Framework Using Authenticated Encryption in Wireless Sensor Networks

Wireless sensor networks (WSNs) are widely used intelligent technology in the century that provides user-oriented better solutions for real-time environment. WSNs have wide range of applications, such as, habitat monitoring, surveillance, location tracking, agriculture monitoring, structural monitoring, wild-life monitoring and water monitoring, are few examples (Akyildiz et al., 2002). Furthermore, numerous other applications require the finegrain monitoring of physical environments which are subjected to critical conditions, such as, fires, toxic gas leaks and explosions. Sensors’ sense the environmental data and transmit to the sink node using wireless communication, as shown in figure 1. Thus the novelty of WSNs is providing inexpensive yet effective solutions for monitoring unattended physical environments. In addition, the ubiquitous nature of WSNs makes environmental data access possible anytime, anywhere in an ad-hoc manner.
