A New Object Oriented Paradigm for Ad Hoc Collaborative Systems

Many-to-Many Invocation (M2MI) is a new paradigm for building collaborative systems that run in wire-less proximal ad hoc networks of xed and mobile computing devices. M2MI is useful for building a broad range of systems, including multiuser applica-tions (conversations, groupware, multiplayer games); systems involving networked devices (printers, cam-eras, sensors); and collaborative middleware systems. M2MI provides an object oriented method call ab-straction based on broadcasting. An M2MI invoca-tion means \Every object out there that implements this interface, call this method. " An M2MI-based application is built by dening one or more inter-faces, creating objects that implement those inter
