Abstract:
In an ad-hoc, peer-to-peer radio system comprising a series of terminals where each said terminal is capable of making at least one of an outgoing call or receiving an incoming call, each said terminal comprising transceiver means for transmitting and receiving signals from other like terminals of said series of terminals, computer means and memory means for storing program software means therein, the improvement comprising:said memory means comprising software means for creating connectivity messaging and data transfer plan messaging information for transmission to other said terminals, and for receiving similar said information from other said terminals from which said terminal can receive; said software means comprising means for delivering said connectivity and data transfer plan information messaging to a configuration channel for transmission to said other terminals belonging to the same service group (SG); said connectivity messaging comprising a utilization map, the power used for transmitting the messaging, and the level of the environmental noise at the transmission site of the transmitting terminal; said data transfer plan information messaging comprising messaging for use in changing the transmit power level and for determining routing paths; and said utilization map comprising information messaging on the availability of time slots of a previous time frame based on whether time slots were used in said previous time frame or were unavailable for use due to high-level noise; said software means further comprising means for generating at least one optimal connection path of a call based on said messaging received from other said terminals in said service group (SG), whereby said call is routed to its destination by routing said call along a route utilizing at least one of some of said terminals of said series of terminals based on least-energy routing, so that the least amount of energy over a selected route is chosen for completing a call.
