摘要：Routing Protocol for Low Power and Lossy Networks (RPL) is one of the most utilized routingprotocols. It designed to adapt with thousands of nodes in energy-constrained networks. It is aproactive distance vector protocol which has two major components objective function andtrickle algorithm. Our work focus on the trickle timer algorithm, it is used to control, maintainand follow the control messages over the network. Short listen problem is the main blot intrickle algorithm. Several studies focused on enlarging the listen period. However, as it wassuffering from node starvation when the period is short, it suffers from time and energy wastingwhen the period is enlarged. Notice that the time and power consumption are sensitive factorsin Low Power and Lossy Networks. In this paper, we propose a randomized dynamic tricklealgorithm, it contributes in the improvement of trickle and solving the above-mentionedproblems by controlling the t variable in a dynamic randomly way, where t is the border linebetween listening and transmitting period. The performance of the proposed algorithm isvalidated through extensive simulation experiments under different scenarios and operationconditions using Cooja 2.7 simulator. Simulation results compared with the standard trickletimer algorithm based on convergence time, packet delivery ratio (PDR) and powerconsumption performance metrics. The results of the simulations denote a high improvement interm of convergence time, power consumption and packet delivery ratio
