Abstract :
In this paper, we consider a variant of the 802.11 protocol augmented with an automatic repeat request (ARQ) mechanism for data transmission. An innovative analysis method that provides the joint distribution of energy and delay via their joint generating function is proposed. The generating function is used to evaluate the average energy and delay of a successful data packet transmission. Our analysis takes into account the effect of channel noise on the transmission of the RTS, CTS, data, and ACK packets. Our analysis indicates that the proposed 802.11 variant performs almost identically to the original protocol and that both are sensitive to the knowledge of channel conditions.
