Low Power and Lossy Networks (LLN) are characterized by stringent energy constraints and frequent communication errors. Recent research in the area of LLNs has focused in solving many issues like security, energy efficiency, and routing. RPL is a new routing protocol proposed for LLNs by IETF ROLL group. RPL provides opportunities for improving overall performance of LLN by providing mechanisms for efficient and secured routing. In this regard, the paper focuses on two objectives. First objective is to analyze the performance of existing link quality and trust based calculations of RPL using J-Sim Simulator. Second objective is to propose some improved methods for calculating trust such that the new variant of RPL will be able to detect and resolve the On-Off attacks which the RPL is unable to do so far. Results and analysis provided in the later part of this paper shows that enhanced RPL variant is able to detect and resolve on-off security attack without introducing any extra performance overhead, thus making the RPL more secured. Paper will be concluded with mentioning future directions for research.
