Users of wireless devices increasingly demand access to multimedia content with specific quality of service requirements. However, different users might tolerate different levels of service, or could be satisfied with different quality combinations choices. We provide semantically rich QoS specification interface for multidimensional QoS provisioning, allowing the user, and applications, to define finegrained service requests. Traditionally, multimedia processing introduces heavy resource requirements on the client side. Our work tries to address this growing demand on resources and performance requirements, by allowing wireless nodes to cooperate with each other, or with wired neighbor nodes, to meet resource allocation requests and handle stringent constraints, opportunistically taking advantage of local network resources and processing power, as nodes move in range of each other, forming a temporary coalition for service execution. We argue that coalition formation is necessary when a single node cannot execute a specific service, and it may also be beneficial when groups perform more efficiently when compared to a single’s node performance.
