   HOME             UNIT 1       UNIT 2   COMPaaS Middleware COMPaaS (Cooperative Middleware Platform as a Service) is an IoT middleware system [3] that has been tailored to support the 5G technology integration. Basically, the goals of the COMPaaS can be summarized as follow: ∙ Abstraction of the integration and interoperation between applications and physical devices through the provision of hierarchical system services according to device profiles (i.e., a set of functional characteristics describing each physical device). ∙ Abstraction of the collection and management of data provided by physical devices through the provision of application-level services. ∙ Provision of high-level services to facilitate the development and integration of IoT applications. ∙ Provision of a software architecture based on IoT/M2M and WoT (Web of Things) standards.   Fig. 5 COMPaaS architecture COMPaaS architecture is based on SOA approach [4] and is composed of two main systems according to F

   HOME             UNIT 1       UNIT 2   Perspectives and a Middleware Approach Toward 5G According to [62], novel middleware architecture approaches toward 5G will not suffer major changes compared to what we have today in terms of SOA-based IoT middleware systems, and hence, the core of the architecture shown in Fig. 3 probably will be maintained. However, as mentioned in Sect. 3, IoT middleware systems will have to support the requirements imposed by 5G which will result in specific changes to allow the applications requirements demanded by 5G. Figure 4 illustrates a possible system architecture for 5G-based IoT Middleware with two application examples: (a) a “Healthcare Monitoring application” oriented to mission-critical services in a hospital (i.e., a group of medical devices and sensors for patients monitoring that continuously route data through redundant networks to guar- antee delivery of priority data), and (b) a non-critical example focused on “Social Networks” as WhatsApp

   HOME             UNIT 1       UNIT 2   Challenges Introduced by 5G in IoT Middleware   Technological Requirements of 5G Systems   5G is a promising technology that has been considered the next step for a long- term worldwide evolution of mobile communication. 5G is intended to be the major component of the networked or IoT/M2M-oriented society, and will help to real- ize the IoT vision toward unlimited access to information and sharing of pervasive data (anywhere and anytime) for anyone (human-centric approach) and anything (device/things-oriented approach) [ 27 ]. The aim of 5G is not only about mobile connectivity for people, but also mobile and ubiquitous connectivity for any kind of computing device and application that may benefit from being connected to the Internet (IoT) and also to the Web (WoT—Web of Things). In order to enable massive connectivity for a very wide range of heterogeneous IoT applications and devices, the capabilities of 5G m

   HOME             UNIT 1       UNIT 2   Middleware Technology for IoT Systems:             Middleware for IoT is the software technology that has been used as the basis for the development, management, and integration of both heterogeneous devices and applications in IoT environments. Despite the intended definition of a horizontal architecture approach (i.e., a common system approach to manage different application domains or verticals) for IoT middleware has been one of the main requirements by global IoT projects during the last years, the imminent arrival of 5G technology is revealing that current middleware approaches possibly will face some challenges due to new application requirements imposed by 5G (e.g., big data bandwidth and infinity, reliable, and efficient capability of networking, joining massive user experiences on mobile communications with multimedia sharing). In this way, this chapter not only pres
