Mobile ad hoc networking allows nodes to form temporary networks and communicate beyond transmitter range by supporting multihop communication through IP routing. Routing in such networks is often reactive, i.e., performed on-demand, as opposed to Internet routing that is proactive. As ad hoc networks are formed on a temporary basis, any IP address should(More)
We present the design, implementation, and evaluation of Mobile*IP, a set of IP-based protocols and mechanisms to support host mobility throughout the Internet. The design requires changes only in the mobile hosts and their special routers; leaves transport and higher protocols unaffected, and requires no changes in the device drivers for individual(More)
This paper presents the implementation strategy and current status of a new Portable LISP System, PSL, based upon STANDARD LISP. PSL is written entirely in itself and is compiled with an efficient LISP compiler with machine-oriented optimizations. A full PSL is currently running on a DECSystem-20 and a VAX, and a preliminary version runs on a Motorola(More)
BACKGROUND It is difficult to assess the orientation of the acetabular component on routine radiographs. We present a method for determining the spatial orientation of the acetabular component after total hip arthroplasty (THA) using computed tomography. PATIENTS AND METHODS Two CT-scans, 10 min apart, were obtained from each of 10 patients after THA.(More)
To enhance the information provided by computed tomography (CT) and single photon emission computed tomography (SPECT) performed with radiolabeled, anti-carcinoembryonic antigen monoclonal antibody (MoAb), the authors performed fusion of these types of images from eight subjects with suspected colorectal adenocarcinoma. Section thickness and pixel size of(More)
This report describes a novel predictive mobility management algorithm for supporting global mobile data accessing. Traditionally, mobility management includes functions to passively keep track of the location of the users/terminals and to maintain connections to the terminals belonging to the system. To make intelligent mobile-aware applications, it is(More)
