Suitability of existing service discovery protocols for mobile users in an ambient intelligence environment

摘要

Service discovery enables users to access information, resources and services anytime, anywhere. This involves a client, a service provider and an infrastructure for service registration and lookup. Clients use service discovery protocols (SDPs) to issue a service request to a service registry or an individual service provider. In this paper we investigate the suitability of existing SDPs for mobile users in an ambient intelligence context After reviewing the most well-known SDPs, common problems in the domain of user mobility and solutions that are currently available are discussed.
