Divya Sharma, Sanjay Jain · Webology · 2022
With the dawn of Internet of Things (IoT), interconnected things and smart applications have significantly reduced human intervention in accomplishing tasks. Yet, due to its openness, heterogeneity, limited resources and extensiveness, it suffers from several issues such as lesser capacity links, energy consumption, resource optimization etc. Routing of packets in such constrained environment is yet challenging. Lightweight On-demand Ad hoc Distance-vector Routing Protocol—Next Generation (LOADng) protocol is an extended version of AODV protocol. Unlike AODV, LOADng is lighter version which forbids the intermediate nodes on the route to send a route reply (RREP) for the route request (RREQ) which is originated from the source. A resource constrained IoT network demands minimal routing control overhead with no packet loss. The optimal selection of routing protocol parameters can improve quality of service (QoS) of such constrained environments. So, in this paper we present optimization of the parameters of LOAD grouting protocol using black widow optimization (BWO) algorithm for IoT. Simulation results depict that the LOADng-BWO outperforms the conventional LOADng protocol in terms of delay, overhead and delivery ratio.
