The IEEE 802.11 family of specifications is by far the most prominent and successful technique for accessing WLANs. Because the channel used by wireless devices is a time-varying broadcast medium, these devices need to have multi-rate and rate-adaptive capability to adapt to the changing channel so that better performance can be achieved. In this paper, we(More)
Power management is one of the most important issues in mobile communications. Much research has been done in reducing wireless station's power consumptions. IEEE 802.11 addresses this issue by adopting a MAC layer active-doze Power Saving Mechanism. In an 802.11 ad hoc network, this Power Saving Mechanism works as follows. Any wireless station with data to(More)
The mobile ad hoc networks (MANETs) have received a lot of attention for its flexible network architecture. While many routing protocols have been proposed for MANETs based on different criteria, few have considered the impact of multi-rate communication capability that is supported by many current WLAN products. Given a routing path, this paper provides an(More)
