Abstract:

In this work, we investigate the tradeoff between energy and delay for wireless networks utilizing the IEEE 802.11 standard for medium access control. The proposed analysis provides the joint distribution of the energy and delay of a transmitted data packet, which is then used to evaluate the corresponding average values. Our analysis takes into account the effect of the channel noise on the transmission of the RTS, CTS, data, and ACK packets. Furthermore, channel coding is incorporated in the analysis by estimating the packet error probability using error-exponent-based bounds under a memoryless channel. Using these analysis tools, the code rate and the signal-to-noise ratio per dimension are optimized to achieve minimum average delay per information bit.
