The IEEE 802.11 standard requires that a beacon station has to stay in awake after generating a beacon frame to serve probe request. This requirement make a reason to consume valuable power of beacon station even though there are no frame exchanges between stations or there exists only one station in the ad hoc network. This paper proposes an ePSM(Enhanced(More)
To exploit multi-rate capability as well as improve performance in wireless local area networks (WLANs), many mechanisms were proposed on IEEE 802.11 media access control (MAC) layer. However, no effort has been invested to exploit the multi-rate capability for power saving mechanism in MAC layer. In this paper, we propose a Voluntary Relaying MAC Protocol,(More)
