Abstract
A wireless communication system, a method for enhancing network efficiency, and a computer program product therefor are provided. The wireless communication system includes a transmitting apparatus and a receiving apparatus. The method and the computer program product therefor perform the following steps. The transmitting apparatus transmits a request-to-send packet to the receiving apparatus. After receiving the request-to-send packet, the receiving apparatus measures a request-to-send power of the received request-to-send packet to calculate a clear-to-send power. The receiving apparatus then uses the clear-to-send power to broadcast a clear-to-send packet. All neighboring transmitting apparatuses that can hear this clear-to-send packet should prohibit themselves from sending packets during the period specified in the clear-to-send packet to avoid colliding with a data packet that will soon be sent from the transmitting apparatus to the receiving apparatus.
