An InfoStation-Based Multi-Agent System Supporting Intelligent Mobile Services Across a University Campus

This paper presents an InfoStation-based multi-agent system, which provides mobile services (mServices) across a University Campus. A description of some of the mServices along with sample interactions among entities is provided. Technologies for delivering of these services are discussed and approaches for the system implementation and structuring are considered.

Network Simulator NS2: Shortcomings, Potential Development and Enhancement Strategies

The basic concept and evolution of the network simulator (NS) is discussed MPLS Network Simulator (MNS) and Wireless Mobile Networking are described with emphasis on conceptual model and architecture. Current NS compatibility issues and shortcomings are considered and a potential development plan is proposed. NS enhancement strategies in terms of enriching various modules with MPLS and HMIPv6 functionalities are proposed and novel schematic embedding algorithms are shown.

An Approach for the Development of a Context-Aware and Adaptive eLearning Middleware

This chapter describes a generic, service-oriented and agent-based approach for the development of eLearning intelligent system architectures providing wireless access to electronic services (eServices) and electronic content (eContent) for users equipped with mobile devices, via a set of InfoStations deployed in key points around a University Campus. The approach adopts the ideas suggested by the Model Driven Architecture (MDA) specification of the Object Management Group (OMG). The architectural levels and iterations of the approach are discussed in detail and the resultant context-aware, adaptive middleware architecture is presented. The classification and models of the supporting agents are presented as well.

A Hybrid Service Recommendation Prototype Adapted for the UCWW: A Smart-City Orientation

With the development of ubiquitous computing, recommendation systems have become essential tools in assisting users in discovering services they would find interesting. This process is highly dynamic with an increasing number of services, distributed over networks, bringing the problems of cold start and sparsity for service recommendation to a new level. To alleviate these problems, this paper proposes a hybrid service recommendation prototype utilizing user and item side information, which naturally constitute a heterogeneous information network (HIN) for use in the emerging ubiquitous consumer wireless world (UCWW) wireless communication environment that offers a consumer-centric and network-independent service operation model and allows the accomplishment of a broad range of smart-city scenarios, aiming at providing consumers with the “best” service instances that match their dynamic, contextualized, and personalized requirements and expectations. A layered architecture for the proposed prototype is described. Two recommendation models defined at both global and personalized level are proposed, with model learning based on the Bayesian Personalized Ranking (BPR). A subset of the Yelp dataset is utilized to simulate UCWW data and evaluate the proposed models. Empirical studies show that the proposed recommendation models outperform several widely deployed recommendation approaches.

Services, Optimization, and Economic Aspects

Future broadband wireless services will involve a range of different technologies, all with varying characteristics.These differences can influence significantly how a service is defined and deployed as well as how it is commercially offered to customers. Key technologies and services that will influence and shape the future broadband telecommunication marketbroadband telecommunication market include WiFi services WiFi services based on IEEE 802.11 standards, enhanced Universal Mobile Telecommunication System (UMTS) services, mobile grid services mobile grid services , incoming call handling services, and finally alternative approaches to broadband access such as high aerial platforms high aerial platforms. Each of these technologies and services has unique requirements in terms of deployment and management.

A New Techno-Business Model Based on a Personal IPv6 Address for Wireless Networks of Moving Objects

A new techno-business model, based on a personal IPv6 (PIPv6) address embedded in an X.509v3 digital certificate, is described in this chapter. The new globally significant, network-independent PIPv6 address class will enable real number ownership and full anytime-anywhere-anyhow portability for future generations of wireless networks of moving objects, such as those in vehicular ad hoc networks (VANETs), mobile ad hoc networks (MANETs), and other types of ad hoc networks. The unique PIPv6 address of the network node (object) could serve as its long-term identity, and enable its advanced secure mobility and participation in the variety of evolving dynamic, fluid wireless mobile network scenarios. It can also serve enhanced authentication, authorization and accounting (AAA) functionality, through which commercially viable ad-hoc networking and open mesh-networking solutions are realizable. In these latter, a mobile node (object) acting as a gateway (or a relay) may offer (or facilitate) wireless Internet access services casually or persistently to other mobile nodes or objects and receive credits for this service. This solution is exactly the kind of incentivised one that is required for cooperative relaying over multiple hops, i.e., that available idle mobile nodes and objects are incentivised to operate and offer service as relay nodes for other objects which are trying to reach a gateway for access to specific or general telecommunications services, such as the Internet. The idle nodes may provide this access directly if that is possible or in a dynamic collaboration via a multi-hop link.

An Intelligent Application for the WBC Application Enabler Sub-layer: Design and Implementation

This paper describes the design and implementation of a new intelligent application, which runs at the application enabler sub-layer of a wireless billboard channel service provider’s (WBC-SP) node. The application is implemented with three tiers: a service discovery and maintenance tier acting as a client-server distributed system for data collection and organization; an intelligent application tier holding all business logic and common application programming interfaces (APIs); and a multi-agent systems (MAS) tier maintaining the advertisement, discovery and association (ADA) agents’ lifecycle.

Service Advertisements’ Formatting for Wireless Billboard Channels

This paper addresses the formal description of services for advertisement on wireless billboard channels (WBCs). As using as little bandwidth as possible is one of the WBC’s desired properties, the basic data structure -the service description (SD)- is formatted with the abstract syntax notation (ASN.1) and encoded/decoded with packed encoding rules (PER). A SD’s template division and an efficient software encoding/decoding architecture are proposed.

Building a WBC Software Testbed for the Ubiquitous Consumer Wireless World

The wireless billboard channels (WBCs) are used by the service providers (xSPs) for broadcasting advertisements of their services to the mobile terminals (MTs) in the ubiquitous consumer wireless world (UCWW). In this paper, a 3-layer model and a software testbed for WBCs based on the digital video broadcasting - handheld standard (DVB-H) are set out.
