MmRPL: QoS Aware Routing for Internet of Multimedia Things

This paper provides an improved version of the routing protocol for low power and lossy networks (RPL), calledmultimedia RPL (MmRPL). This protocol is proposed as a solution for some restrictions in the RPL storing mode. RPL consumes much energy when the network size increases which may degrade its performance and cause a degradation of the network performance, resulting in an inconsistency in the use of the RPL protocol in constrained internet of multimedia things (IoMT) networks. IoMT applications can be very demanding in terms of quality of service (QoS) requirements such as minimum delay, reduced rate of control overhead and low-energy consumption. The proposed extension overcomes the memory overload challenge and improves the QoS requirements in IoMT networks. The obtained simulation results proved that the proposed algorithm outperforms the standard RPL and another extension of RPL, in terms of control-plane overhead, end-to-end delay and energy consumption.
