Energy-Delay Analysis of MAC Protocols in Wireless Networks
In this paper the tradeoff between energy and delay for wireless networks is studied. A network using a request-to-send (RTS) and clear-to-send (CTS) type medium access control (MAC) protocol is considered. We first determine the average delay incurred and the average energy consumed when the effects of an imperfect channel are incorporated in the model. In order to incorporate the relation between packet error probability, energy, and delay, we use the reliability function bounds on the error probability of a coded system. Further, we present a generic framework that allows us to obtain the joint statistics of energy and delay through their joint generating function. Several important design tradeoffs are studied from the joint generating function, such as the average energy with an outage delay constraint. This framework allows us to optimize over the system parameters for various objective functions, such as average delay. An approximation method is also proposed to calculate the a...
