A BSTRACT Addressing in IPv6 networks is a complex task, that involves multiple decision criterion that include base addressing, subnet addressing, location & energy aware addressing, and temporal performance aware addressing constraints. To incorporate these constraints a wide variety of models are proposed by researchers, and most them utilize location-aware addressing and do not consider multimodal parameters. Schemes that consider these parameters are either highly complex, or cannot be scaled for heterogeneous network scenarios. To overcome these limitations, this text proposes design of a novel hybrid bioinspired model that assists in improving addressing capabilities of IPv6 networks. The proposed model bee colony optimization (BCO), genetic algorithm (GA), and particle swarm optimization (PSO) in order to improve addressing quality for diferent network types. Initially, GA is used to stochastically assign location-specifc addresses to a simulated network, which is incrementally tuned by PSO via a cognitive & social learning process. The fne-tuned addresses are further optimized via integration of BCO model, which assists in integrating energy awareness. Final addresses are initially simulated with exhaustive communication test, and then deployed to real-time networks for optimized operations. Due to which, the assigned addresses are observed to be delay & energy efcient, thereby assisting in deploying them for real-time use cases. The proposed addressing model was tested under diferent scaled networks, and an energy efciency of 8.3%, with delay reduction of 6.5% was achieved when compared with various state-of-the-art methods, which assists in deploying the model for multiple scaled network scenarios.

ORIGINAL RESEARCH SAMRIDDHI Volume 14, Issue 4, 2022 Print ISSN: 2229-7111 Online ISSN: 2454-5767 I NTRODUCTION I Pv6 network address assignment is a multi-domain task that includes the development of location-aware address evaluation, as well as ongoing network monitoring and performance optimization. In this process, routing prefx- based addresses are first assigned to core routers for subnetting, and then region-based router nodes extend those addresses to include client nodes’ interface identifers (IDs). This 3-step addressing scheme makes it easier for routers to identify nearby nodes for low-power and high-speed routing performance. Routing prefxes must be assigned to nodes that are closer in proximity in order to design such addressing schemes. Similarly, subnet addresses must be assigned in order to facilitate the identifcation of nearby access nodes during the routing process. [1] Some researchers use these operations as a foundation for various addressing models that have varying degrees of computational latency, energy efciency and applicability. IPv6 addressing has multiple applications, for instance, it can be applied on the internet control message protocol (ICMP), which uses communication between a PC node and a router via switching devices. IPv6 header and ICMPv6 header are frst defned by a PC in the model, which is then passed through a switching device for communication checks. IPv6 subnet address identifcation, routing address extraction, and network ID evaluation are all part of these checks. The router uses these IDs to verify packets, which allows it to allow or deny diferent communi- cation requests. Next section discusses similar models, [2-4] as well as their network specifc nuances; application-specifc advantages; functional limitations; and contextual future
