Performance Evaluation of "Dynamic Double Trickle Timer Algorithm" in RPL for Internet of Things (IoT)

Internet of Things (IoT) is a modern technology which used to support a variety of domains and applications in life. It is based on connecting various devices which can communicate with each other without the need for human intervention. Low Power and Lossy Networks (LLN), which already used IOT techniques, suffer from limited energy and resources. Special protocols have been designed for LLN, like RPL which uses the Trickle Timer algorithm, it turns to the act as a router and organizer for transmission of messages in the network. However, the trickle algorithm suffers from performance deficiency problems such as prolonged time and high power consumption. Therefore, there are such efforts to develop Trickle Timer algorithm to solve performance shortcomings in the algorithm. This work is an attempt to enhance the trickle timer algorithm to overcome delay and energy consumption problems, using dynamic doubling technique. Researchers used Cooja 2.7 simulator to evaluate the performance of the proposed algorithm by using several metrics: packet delivery ratio, convergence time and power consumption. The simulation examined under different scenarios. It also showed better results in performance and lower energy consumption of the proposed algorithm.
