SharedSpace Based Service Discovery Mechanism and Its Implementation for Ubiquitous Environments
نویسندگان
چکیده
We propose a new service discovery method based on SharedSpace concept. SharedSpace is a virtual community space for service registration and sharing, which is similar to a chat room in a chat system. Any user can freely create a SharedSpace and register his/her services. Others can join the created SharedSpace as members and register their services. All registered services can be shared by the SharedSpace members as if they are in a single network. Detailed mechanism is designed and implemented with Obje middleware in order to validate our scheme.

JCSP Agents-Based Service Discovery for Pervasive Computing
Device and service discovery is a very important topic when considering pervasive environments. The discovery mechanism is required to work in networks with dynamic topology and on limited software, and be able to accept different device descriptions. This paper presents a service and device discovery mechanism using JCSP agents and the JCSP network package jcsp.net2.
متن کاملSupporting QoS-aware Service Discovery in Ubiquitous Computing Environments. (Découverte de services sensible à la qualité de service dans les environnements de l'informatique diffuse)
With the advent of portable devices (e.g., smartphones) and the advances in wireless networking technologies (e.g., WLAN, GPRS, UMTS), the vision of ubiquitous computing is becoming a reality. It aims to facilitate user tasks through the seamless utilization of heterogeneous computing and communication capabilities (represented as services) available in the environment. Service discovery, which...
متن کاملAccess to Local Resources in a Nomadic Environment
We propose a standard level of support for nomadic computing in which a mobile client can move into unfamiliar environments and obtain services for which it has no corresponding client RPC stub. We call this activity service discovery and motivate its importance for mobile computing. This paper describes the general components of service discovery and points out where traditional paradigms of d...
متن کاملContext gathering in Ubiquitous Environments: Enhanced Service Discovery
Delivering individualized services that conform to the user’s current situation will form the focus of ubiquitous environments. A description of the networked environment at a semantic level will necessitate contextually oriented knowledge acquisition methods. This then engenders unique challenges for the crucial step of resource discovery. A number of service discovery protocols exist to perfo...
متن کاملActivity-Based Service Discovery – An Approach for Service Composition, Orchestration and Context-Aware Service Discovery
Service Discovery is a core enabling technology for users in mobile and ubiquitous computing. However, most of the existing protocols for service discovery works on a low level and do not provide support for higher-level service abstraction, composition, and orchestration. Nor do they support service discovery tailored to the mobile user’s context. This paper presents the principles of Acitvity...
