Abstract: 
The routing protocol for low-power and lossy networks (RPL), designed by the Internet Engineering Task Force (IETF), is specially standardized for use in low-power and lossy networks (LLNs) with complex and harsh communication conditions. To improve the network performance of LLNs, in this paper we propose a novel context aware RPL algorithm based on a triangle module operator (CAR-TMO). CAR-TMO designs a novel composite context aware routing metric (CA-RM) which synchronously evaluates the residual energy index and buffer occupancy ratio of a node, expected transmission count (ETX), delay, and hop count from a candidate parent to the root. CA-RM considers the residual energy index and buffer occupancy ratio of the candidate parent and its preferred parent in a recursive manner to reduce the effect of upstream parents, since farther paths are considered. CA-RM comprehensively uses the sum, mean and standard deviation values of ETX and the delay of links in a path to ensure better performance. Moreover, CAR-TMO designs the membership function of each of the above routing metrics. Then, CAR-TMO constructs a comprehensive membership function based on a triangle module operator and the membership function of each routing metric, and a comprehensive context aware objective function (CA-OF). A novel mechanism for calculating the rank of nodes, and mechanisms for preferred parent selection are proposed. Finally, theoretical analysis and simulation results show that CAR-TMO outperforms several recent representative RPL algorithms in terms of packet delivery ratio and energy efficiency.
