TLDR
The concept of context attribute is introduced as an effective, flexible means to exploit relevant context information during the service discovery process to express context information including service-specific selection logic, client, and network condition.Abstract:
The service discovery problem has attracted a lot of attention from researchers and practitioners. Jini, SLP, and UPnP are among the few emerging service discovery protocols. Although they seem to provide a good solution to the problem, there is an unaddressed need of more sophisticated location and context-aware service selection support. In this paper, we introduce the concept of context attribute as an effective, flexible means to exploit relevant context information during the service discovery process. Context attributes can express context information including service-specific selection logic, client, and network condition. We describe our approach and implementation, and present experimental results of our context-aware service discovery implementation.read more

Context-Aware Migratory Services in Ad Hoc Networks
TL;DR: This work proposes a novel model of service provisioning in ad hoc networks based on the concept of context- aware migratory services, and built TJam, a proof-of-concept migratory service that predicts traffic jams in a given region of a highway by using only car-to-car short-range wireless communication.

Service Location Protocol, Version 2
TL;DR: The Service Location Protocol provides a scalable framework for the discovery and selection of network services for network based applications and is especially important as computers become more portable, and users less tolerant or able to fulfill the demands of network system administration.
Service Location Protocol
TL;DR: Using this protocol, computers using the Internet no longer need so much static configuration of network services for network based applications, which is especially important as computers become more portable, and users less tolerant or able to fulfill the demands of network system administration.
Host Anycasting Service
TL;DR: This RFC describes an internet anycasting service for IP and tries to be agnostic about how the service is actually provided by the internetwork.
