Appear Research Labs Presents at the SNCNW ’09 & Adhoc ’09 Conference at Uppsala University
6:th Swedish National Computer Networking Workshop (SNCNW’09)
9th Scandinavian Workshop on Wireless Adhoc Networks (Adhoc’09)
Date & Place: May 4-5, Uppsala University, Sweden
Abstract:
SIP/SIMPLE event notifications leverage a centralized architecture where a SIP presence server handles publications, subscriptions, and communicates the notifications to the subscribers. Although this
centralized architecture can easily scale up by adding new servers, there are open issues regarding the redundancy and fault resiliency of that design. In order to mitigate these effects we propose a P2PSIP
event notification architecture that distributes the SIP/SIMPLE notification process within a peer overlay. Utilizing a peer overlay yields a solution with enhanced scalability, redundancy, as well as failure and recovery features. At the same time SIP user agents continue to transparently access the overlay as they would in a centralized SIP notification architecture.
About the conference:
SNCNW, the Swedish National Computer Networking Workshop, is a creative and informal forum for researchers and practitioners in computer communication and networking. The main objective of SNCNW is to give all research and development groups an opportunity to present their work. The workshop also provides an excellent opportunity to discuss ideas among colleagues and establish contact between computer network researchers, practitioners and industry, and thus to help strengthen this field in Sweden.
The Scandinavian Workshop on Wireless Adhoc Networks waims at bringing researchers in the field of wireless ad-hoc networking and wireless sensor networks together for discussions in an informal setting. The focus of the workshop is on theoretical and experimental studies on self-organization and/or multihop wireless networks.
The 6:th Swedish National Computer Networking Workshop SNCNW will be held together with the 9th Scandinavian Workshop on Wireless Adhoc Networks (Adhoc’09) at Uppsala University in May 2009.
