EMA-RPL: Energy and mobility aware routing for the Internet of Mobile Things (2019)
Belghith, Abdelfettah . 2019
Internet of Mobile Things (IoMT) is a new paradigm of the Internet of Things (IoT) where devices
are inherently mobile. While mobility enables innovative applications and allows new services, it
remains a challenging issue as it causes disconnection of nodes and intermittent connectivity, which
negatively impacts the network operation and performance. In addition, energy saving presents a real
challenge for networks with limited resources. In this context, a new energy efficient and mobility
aware routing protocol called EMA-RPL is proposed based on the well-known Routing Protocol for Low
power and Lossy Networks (the RPL standard). Unlike the RPL which is basically designed for static
devices, EMA-RPL enables better sustaining of connectivity of mobile nodes and conserving energy. The
proposed protocol integrates an enhanced mobility detection method through a continuous control of
the distance between the mobile node and its attachment, a novel point of attachment prediction
based on the new location of the mobile node, and an efficient replacement strategy preserving the
mobile node energy. EMA-RPL overcomes and mitigates problems caused by the mobility of nodes.
Simulations using Cooja/Contiki show that EMA-RPL outperforms both the RPL and its mobility aware
variant (MRPL) in terms of handover delay, data loss rate, signaling cost and energy consumption.
