E-RPL: A Routing Protocol for IoT Networks
Abdelhak Zier, Abdelhafid Abouaïssa, Pascal Lorenz · 2018
Internet of things is the new era of networking and smart communication. Recent researches treat some issues and challenges of IoT. QoS routing protocols for IoT have been a rising research topic for years. In this paper we present a new approach called E-RPL; it is an enhancement of the Routing Protocol for Low power and lossy networks (RPL). Comparing to RPL, E-RPL decreases the number of control messages. The new protocol proposes also a new flexible multi-constrained objective function (OF) that can integrate several metrics including energy, delay and bandwidth to define the end-to-end path between the sink and a given node. The simulation results show a remarkable improvement of energy consumption, routing overhead, and end-to-end delay.
