A New Framework for Building Secure Collaborative Systems in Ad Hoc Network

Free registration required

Executive Summary

Many-to-Many Invocation (M2MI) is a new paradigm for building secure collaborative systems that run in true ad hoc networks of fixed and mobile computing devices. M2MI is useful for building a broad range of systems, including service discovery frameworks; groupware for mobile ad hoc collaboration; systems involving networked devices (Printers, Cameras, Sensors); and collaborative middleware systems. M2MI provides an object oriented method call abstraction based on broadcasting. An M2MI invocation means ''Every Object Out There That Implements This Interface, Call This Method.'' M2MI is layered on top of a new messaging protocol, the Many-to-Many Protocol (M2MP), which broadcasts messages to all nearby devices using the wireless network's inherent broadcast nature instead of routing messages from device to device.
