Users of wireless devices increasingly demand access to multimedia content with specic quality of service requirements. Users might tolerate dierent levels of service, or could be satisfied with different 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 specific service, but it may also be bene cial when groups perform more efficiently when compared to a single's node performance.
