Patent ID: 8817630

Claim:
A device, comprising: a receiver; a transmitter having a transmission perimeter; processing electronics coupled to the receiver and the transmitter, wherein the processing electronics are configured to recognize a message received from each of a plurality of transmitting nodes; and wherein the processing electronics are configured to determine whether to retransmit the message by determining whether any portion of the transmission perimeter expands beyond a combined transmission area formed by the each of the plurality of the transmitting nodes, wherein perimeter arc segments are used to determine whether a portion of the transmission perimeter expands beyond the combined transmission area, wherein the processing electronics suppresses retransmission of the message by the transmitter when the transmission perimeter is completely within the combined transmission area within a predetermined time from when the receiver first receives the message and wherein the transmitters retransmits the message when the transmission perimeter is not determined to be completely within the combined transmission area within the predetermined time from when the transmitter first receives the message.
