ABSTRACT: Energy efficiency plays vital roles in
wireless communication system due to the “energy limited battery service” of a
mobile station (MS). To ensure longer battery life in WiMAX, a new protocol has
been introduced in its IEEE802.16m version. This new sleep mode has extended
listening window and adjustable sleep cycle length. In this paper, we analyze
the probability of attaining at three states: serving state, state of timer
inactivity and silent state in a simplified statistical model using traffic parameters
of arrival rate, pdf (probability density function) of interarrival time and
its threshold value. Finally we developed a new state transition chain of the
above three states of a MS of IEEE802.16m and solved the chain in closed form.
