Abstract(s)
Users of wireless devices increasingly demand access to multimedia
content with speci c quality of service requirements. Users might
tolerate di erent levels of service, or could be satis ed with di erent
quality combinations choices. However, multimedia processing introduces
heavy resource requirements on the client side.
Our work tries to address the growing demand on resources and performance
requirements, by allowing wireless nodes to cooperate with
each other to meet resource allocation requests and handle stringent
constraints, opportunistically taking advantage of the local ad-hoc network
that is created spontaneously, as nodes move in range of each
other, forming a temporary coalition for service execution. Coalition
formation is necessary when a single node cannot execute a speci c service,
but it may also be bene cial when groups perform more e ciently
when compared to a single s node performance.
