<strong></strong>An Energy and Load Aware Multipath Routing Protocol in the Internet of Things

Abstract

Internet of things (IoT) is a network of smart things. This indicates the ability of these physical things to transfer information with other physical things. The characteristics of these networks, such as topology dynamicity and energy constraint, challenges the routing problem in these networks. Previous routing methods could not achieve the required performance in this type of network. Therefore, developers of this network designed and developed specific methods in order to satisfy the requirements of these networks. One of the routing methods is utilization of multipath protocols which send data to its destination using routes with separate links. One of such protocols is RPL routing protocol. In this paper, this method is improved using composite metrics which chooses the best paths used for separate routes to send packets. We propose Energy and Load aware RPL (ELaM-IoT) protocol, which is an enhancement of RPL protocol. It uses a composite metric, calculated based on remaining energy, hop count, Link Expiration Time (LET), load and battery depletion index (BDI) for the route selection. In order to evaluate and report the results, the proposed ELaM-IoT method is compared to the ERGID and ADRM-IoT approaches with regard to average remaining energy, and network lifetime. The results demonstrate the superior performance of the proposed ELaM-IoT compared to the ERGID and ADRM-IoT approaches.

Fluid-Flow Approximation in the Analysis of Vast Energy-Aware Networks

“…Following the development of edge computing, cloud computing, and 5G networks, the most recent focus includes migration methods and scheduling certain tasks from local devices to remote cloud processing [38,39], energy management systems focused on security [40], task allocation algorithms in multi-cloud networks [41], and energy-aware video streaming for mobile devices [42,43]. Increasingly more works are also related to energy saving in the context of Internet of Things networks, e.g., [44][45][46].…”
