摘要: A new approach for collision avoidance and detection in ad-hoc networks of nodes with half-duplex radios is introduced. Rather than using a single busy tone indicating that receiver busy, three types carrier tones sent by receivers or passive listeners indicate an intended receiving acknowledging data packet, listener has detected collision. All are over control channel, the channel used only request-to-send (RTS) packets. The Carrier-Tone Multiple Access Collision Avoidance Detection (CTMA/CAD) described its performance compared DBTMA hidden-terminal scenario. results analysis show CTMA/CAD more efficient channel-access method hidden terminals.
