NODE AND SYSTEM FOR MULTI-HOP MULTI-RADIO MOBILE AD HOC NETWORK, AND NETWORK FORMATION METHOD THEREFOR

摘要

A method for forming an energy-efficient multi-hop multi-radio mobile ad hoc network based on application demands is provided to increase the energy efficiency of mobile devices by activating and using only a radio interface for satisfying a demand for an application. A network is divided into a control plane for transmitting a control message and a data plane for transmitting data. In this case, there are provided a part allowing exchanging of the control message when data transmission is required in a state that a low-power radio interface that every node has commonly is always activated, and a part for configuring the data plane by activating a required network interface according to a request of an application. A state for forming a network is established by performing a soft-state multi-hop signaling protocol through the control plane. In detail, a transmitter establishes a state for forming a network for devices on a path from the transmitter to a receiver by using a request of an application. The state established in each device is updated by repeatedly transmitting a request periodically to the transmitter. When a desired operation is finished in the application or if it is not necessary to maintain the established state any longer, the established state is released.
