# An Optimized Framework for WSN Routing in the Context of Industry 4.0
###### Abstract  
The advancements in Industry 4.0 have opened up new ways for the structural deployment of Smart Grids (SGs) to face the endlessly rising challenges of the 21 st century. SGs for Industry 4.0 can be better managed by optimized routing techniques. In Mobile Ad hoc Networks (MANETs), the topology is not fixed and can be encountered by interference, mobility of nodes, propagation of multi-paths, and path loss. To extenuate these concerns for SGs, in this paper, we have presented a new version of the standard Optimized Link State Routing (OLSR) protocol for SGs to improve the management of control intervals that enhance the efficiency of the standard OLSR protocol without affecting its reliability. The adapted fault tolerant approach makes the proposed protocol more reliable for industrial applications. The process of grouping of nodes supports managing the total network cost by reducing severe flooding and evaluating an optimized head of clusters. The head of the unit is nominated according to the first defined expectation factor. With a sequence of rigorous performance evaluations under simulation parameters, the simulation results show that the proposed version of OLSR has proliferated Quality of Service (QoS) metrics when it is compared against the state-of-the-art-based conventional protocols, namely, standard OLSR, DSDV, AOMDV and hybrid routing technique.

networking for heterogeneous systems are very challenging due to the diversified requirement of QoS for smart industry applications [3]. Therefore, it is very crucial to understand the need for QoS suite/metrics in industrial processes for deploying the communication framework of Industry 4.0 [4]. The Quality-of-Service (QoS) attentive cooperative communication in IoT applications such as Smart Grids (SGs) is reliant on various performance measures/metrics such as time, stability, network lifetime, and complexity. In SGs, a broad range of Mobile Ad hoc Network (MANET) mechanisms have been presented in the literature so far. However, intelligent SGs Industry networks cannot be facilitated by traditional protocols of MANET. They make data communication a challenging task for SGs applications. Under hostile environments, quality-aware metrics such as latency, network lifetime, reliability, and complexity are the major issues of SGs. Hence, the process of optimization is required in traditional communication protocols of MANET for SGs Industry 4.0. The connectivity between nodes in MANET is processed directly without any interference of fixed equipment in the particular mobility administration of MANET. Optimized Link State Routing (OLSR) is considered as an effective MANET protocol, which is used for ensuring a destination track in a routing list [5]. We examined two protocols, Ad hoc On-Demand Distance Vector (AODV) [6] as a responsive show and OLSR as a proactive show for Industry networks. To deal with above-mentioned challenges, this paper proposes an improved OLSR protocol for SGs in MANET to improve the management of control intervals that enhances the efficiency of the standard OLSR protocol without affecting its reliability. The adopted process of grouping reduces the total energy costs by reducing severe flooding in evaluating a head of clusters and has improved the communication services in SGs. Problem Definition and MotivationThe prime motive of the SG Industry 4.0 is to offer a smart electricity paradigm by use of innovative IoT technologies to provide various benefits in the emerging fields: industry economy, constrained sources of energy, reliability, network stability, security, etc. [7]. In SG Industry 4.0, the subsystems and components of the framework will be inter-operable and collaborate strictly. This focuses on the optimizations in the existing frameworks of MANET. One of the famous and existing approaches forms a MANET among the sensor nodes, which is based on the controlling of messages in wireless communication is OLSR that is suitable only for SGs traditional paradigms.
