Integration of WSAN Into SCADA Systems for Managing Critical Infrastructure Hammed Babatunde Rasak Faculty of Science and Technology Bournemouth University Dorset, United Kingdom e-mail: s5305025@bournemouth.ac.uk Abstract—Integration of wireless sensors and ac- tuator networks (WSANs) into a supervisory control and data acquisition (SCADA) network to effectively oversee the critical infrastructure (CI) involves tech- nical challenges requiring a solution. The Integration of WSAN into SCADA frame- works establishes a novel way of broadening SCADA's reach and cost-effectively mitigating the real-time data transmission issues faced with SCADA systems as WSAN incorporates emerging technology, applica- tions, and features. An integration solution that adopts both a gateway, web, and mobile applications service approach that makes the incorporated platforms available online via the cloud services (Internet) is presented in this paper. And a contextual investigation, where WSAN and SCADA integration successfully monitored the power distribution grid, is also presented.

INTRODUCTION Supervisory control and data acquisition net- works are deployed extensively to manage dispersed equipment in telecommunication, transportation, and power grid networks [1]. They work within the critical national assets where safety, standards, and security are crucial elements. Because of this, con- forming to strict administrative principles is a must [2]. Customarily, the SCADA framework is deploy- able in a concrete way together with the focal data center (DC) and excessive wiring to associate diverse equipment with the DC [3]. Because of the limited access to this wired element, conventional security arrangement centers around physical measurements for safety [4]. Recently, recognition of WSAN technology as promising for the CI monitoring field came up [5]. flexibility of WSAN deployment can turn into a vital piece of CIM [6]. In contrast to wired frameworks, their auto organization and distributed nature make them impervious to assaults and failures [7]. In any case, to exploit WSAN, the conventional SCADA networking measures need to change to oblige this technology. For instance, actualizing se- cure data communication methods from the sensors to the unified SCADA should be accomplished. The integration issues of WSAN into a SCADA frame- work were inclusive in the European project (WSAN4CIP) aims [8] and is the setting origin that we use for demonstrating a solution to the Integra- tion of WSAN into SACADA challenges. We demonstrate a solution produced for WSAN into SCADA integration. The framework utilizes web-based-SCADA named Mango, open-source web services, and Internet Protocol (IP) [9]. WSAN4CIP deploy two authentication ideas for de- monstrators to monitor drinking water distribution and the power grid system [10]. This paper centers around the methodology fol- lowed to incorporate WSAN into the SCADA framework and how it applies to the demonstrator. Hence assign the Energias de Portugal (EDP) demon- strator of the electricity distribution organization. This report paper mainly centers on the method adopted for WSAN into SCADA integration and the process applied afterward. Demonstrator designates the Energias de Portugal (EDP) de- monstrator, which shows the electricity distri- bution company's name (EDP). Information about the WSAN4CIP and its overall mechanism is in [11]. A. Related Work Past works identified with SCADA into WSAN are [12] and [13]. The majority of these new propo- sitions follows the specific line listed below: • Specific recommendation introduced in this pa- per where the sensor network also supports a subsystem • Replacement of existing SCADA network with a WSAN IP enabled in the majority of the sug- gestions. Table 1 below displays the new WSAN method and a new proposal introduced with the conventional SCADA framework.
