Analysis of routing protocol for Low Power and Lossy Networks (RPL) using Cooja simulator

Recently, Low Power and Lossy Networks (LLNs) have become a subject of interest for different real time applications. It has become one of the most interesting research areas. These networks are often optimized to save energy and better utilization of limited resources available. Energy conservation while maintaining the performance of network is a major concern in such network. Internet Engineering Task Force (IETF) RoLL has developed a routing protocol for sensors networks, RPL (Routing Protocol For Low Power and Lossy Networks). It's a flexible protocol which allows large scale communicating objects with limited memory, energy and power constraints in Wireless Sensor Networks (WSN). RPL specifications are complex and existing implementation is still under study for better performance. It is important to note that RPL works in networks with lossy links and has ability to adapt various topologies. The aim of this paper is to study the working of RPL using Cooja simulator and performance analysis using different parameters. It will help researchers to contribute more towards RPL.
