Routing Protocol for Low Power and Lossy Networks (RPL) is one of the most utilized routing protocols. It designed to adapt with thousands of nodes in energy-constrained networks. It is a proactive distance vector protocol which has two major components objective function and trickle algorithm. Our work focus on the trickle timer algorithm, it is used to control, maintain and follow the control messages over the network. Short listen problem is the main blot in trickle algorithm. Several studies focused on enlarging the listen period. However, as it was suffering from node starvation when the period is short, it suffers from time and energy wasting when the period is enlarged. Notice that the time and power consumption are sensitive factors in Low Power and Lossy Networks. In this paper, we propose a randomized dynamic trickle algorithm, it contributes in the improvement of trickle and solving the above-mentioned problems by controlling the t variable in a dynamic randomly way, where t is the border line between listening and transmitting period. The performance of the proposed algorithm is validated through extensive simulation experiments under different scenarios and operation conditions using Cooja 2.7 simulator. Simulation results compared with the standard trickle timer algorithm based on convergence time, packet delivery ratio (PDR) and power consumption performance metrics. The results of the simulations denote a high improvement in term of convergence time, power consumption and packet delivery ratio
