Wireless access to Internet services will become typical, rather than as it is today, the exception. Such a vision presents great demands on mobile networks. Mobile IP represents a simple and scalable global mobility solution but lacks support for fast handoo control and paging found in cellular telephony networks. In contrast, second and third generation(More)
We present a performance comparison of a number of key micro-mobility protocols that have been discussed in the IETF Mobile IP Working Group over the past several years. IP micro-mobility protocols complement Mobile IP by offering fast and seamless handoff control in limited geographical areas and IP paging in support of scalability and power conservation.(More)
This paper introduces PARO, a power-aware routing optimization that helps to minimize the transmission power needed to forward packets between wireless devices in ad hoc networks. Using PARO, one or more intermediate nodes called " redirectors " elects to forward packets on behalf of source-destination pairs thus reducing the aggregate transmission power(More)
This paper introduces PARO, a dynamic power controlled routing scheme that helps to minimize the transmission power needed to forward packets between wireless devices in ad hoc networks. Using PARO, one or more intermediate nodes called " redirectors " elects to forward packets on behalf of source–destination pairs thus reducing the aggregate transmission(More)
In this paper, we investigate the impact of variable-range transmission power control on the physical and network connectivity, on network capacity, and on power savings in wireless multihop networks. First, using previous work by Steele (1988), we show that, for a path attenuation factor a = 2, the average range of links in a planar random network of A(More)
For wireless channels, interference mitigation techniques are typically applied at the packet transmission level. In this paper, we present the Havana Framework for supporting integrated adaptive-QOS that also responds to impairments over multiple time scales that are present at the flow/session level. Our framework is based on three different mechanisms(More)
BACKGROUND OVA-301 is a large randomized trial that showed superiority of trabectedin plus pegylated liposomal doxorubicin (PLD) over PLD alone in relapsed ovarian cancer. The optimal management of patients with partially platinum-sensitive relapse [6-12 months platinum-free interval (PFI)] is unclear. PATIENTS AND METHODS within OVA-301, we therefore now(More)
As the number of Mobile IP users grows, so will the signaling overhead associated with Internet mobility management in the core IP network. This presents a significant challenge to Mobile IP as the number of mobile devices scale-up. In cellular networks, registration and paging techniques are used to minimize the signaling overhead and optimize the mobility(More)
