Service-Oriented Network Sockets
This paper presents the design and implementation of service-oriented network sockets (SoNS) for accessing services in a dynamically changing networked environment. A service-oriented network socket takes a high-level description of a service and opportunistically connects to the best provider of that service in the changing characteristics of a mobile system. An application states its high-level service requirements as a set of constraints on the properties required in a suitable resource and SoNS continuously monitors, evaluates and compares the available resources and (re-)connects to the resource that best satisfies the specified constraints.
Unlike content-based routing systems, SoNS is an end-host system, interposed at the session-binding layer, and offers connection-oriented semantics. SoNSÕ interface allows an application to tailor the planning policy used to establish and rebind a network session. SoNS is based on an extensible architecture to leverage the wide-range of emerging technologies for discovering and locating resources in a mobile system.
SoNS integrates a service-oriented abstraction with the traditional operating system interface for accessing network services, making it simpler to develop pervasive, mobile applications. We present an implementation for a mobile handheld device, analyze the performance of our system and describe an application to demonstrate the utility of our system.
