Abstract:
Nowadays, we are witnessing a growing interest for collaborative
working environments (CWEs). The proliferation
of portable devices along with the widespread availability
of wireless network connectivity is converting mobile adhoc
networks (MANETs) into a basic scenario where impromptu
collaborations take place. Recently, several collaborative
middlewares have recently emerged for developing
new collaboration tools. However, it is not easy to
find a middleware for MANETs that enables building applications
from scratch, rapidly and easily, while providing
enough reliability. To cope with this, we present SCOMET,
a middleware that permits the provisioning of collaborative
services over MANETs. It provides efficient group communication
and membership services, which are known to
be critical for collaborative environments. To address oneto-
many communication, SCOMET proposes a new Application
Layer Multicast protocol (ALM) called OMCAST.
Designed to deal with the specific requirements of CWEs,
OMCAST benefits from the broadcast nature of the wireless
medium to minimize communication delays and congestion.
Evaluation results show that OMCAST achieves better network
performance than existing approaches
