ABSTRACT
The power consumption of the network interface plays a major role in determining the total operating lifetime of wireless networked embedded systems. In case of on-demand paging, a low power secondary radio is used to wake up the higher power radio, allowing the latter to sleep for longer periods of time. In this paper we present use of Bluetooth radios to serve as a paging channel for the 802.11b wireless LAN. We have implemented an on-demand paging scheme on an infrastructure based WLAN consisting of iPAQ PDAs equipped with Bluetooth radios and Cisco Aironet wireless networking cards. Our results show power saving ranging from 23% to 48% over the present 802.11b standard operating modes with negligible impact on performance.

Design and performance analysis of a dynamic-paging AAA mobility management scheme for PMIPv6-based wireless networks
Proxy mobile IPv6 (PMIPv6) is a network-based mobility management protocol. It does not require the involvement of the mobile node (MN) in mobility management. However, MN between the mobile access gateway (MAG) and the local mobility anchor (LMA) in a ...
Dynamic multi-step paging scheme in PMIPv6-based wireless networks
In Proxy Mobile IP (PMIPv6) networks, proxy-registrations are performed even for idle MNs, resulting in unnecessary signaling traffic. Although there have been many IP paging techniques aimed at reducing the unnecessary location update, they focus only ...
