RFID Technology and Applications

Abstract: Radio frequency identification is a wireless communication technology that lets computers read the identity of inexpensive electronic tags from a distance without requiring a battery in the tags. As RFID technology matures, it will likely unleash a new wave of applications that will exploit inexpensive and highly available automatic identification.

System and method for service quality management for wireless devices

Abstract: A system and method for detecting and recording events related to the quality of service experienced by a wireless device in a wireless network. In one example, these events may be detected and recorded by the wireless device, without support from the network. Performance monitoring tests may be initiated by the wireless device at the direction of a management server, independent of the network in which the device may be operating. The wireless device may store the results of these tests and report the results to the management server.

System and method for monitoring and measuring end-to-end performance using wireless devices

Abstract: A system and method by which a mobile wireless device dynamically decides the other end host to initiate a session to automatically conduct a performance test. Results of the performance test are then transferred to a monitoring server under appropriate conditions. A method for conducting a performance test on a wireless device comprises receiving information indicating how and when a performance test is to be conducted by the wireless device, determining whether the conditions for the performance test to be started are met, conducting the specified performance test, and storing results of the performance test.

System and method for automatically altering device functionality

Abstract: A system and method for automatically altering device functionality based on the occurrence of certain predetermined conditions. A link may be established between a device and a trusted server to provide an association between various conditions that may be detected at the device and actions that are to be taken on the device. In particular, software traps can be set up and linked to device functionality such that execution of the trap may automatically disable or enable certain device capabilities. Some aspects of the invention are directed to a system and method for remotely setting software traps for detecting software viruses and, upon execution of the traps, several methods for establishing a quarantine on infected devices.

System and method for trap management and monitoring on wireless terminals

Abstract: A wireless device and a method for providing remote trap management of the wireless device by which a management server remotely sets a trap whose trigger needs to be monitored. A method for providing remote trap management of a wireless device comprises receiving from a remote device a request to install a trap on the wireless device, installing the trap on the wireless device, generating trap status information upon occurrence of a trap and transmitting the trap status information to the remote device in response to the occurrence of the trap.

Analysis of Resource Increase and Decrease Algorithm in Wireless Sensor Networks

Abstract: In this paper, we first attempt to formally define the resource control framework that adjusts the resource provisioning at the hotspot during congestion. In an effort to find the optimal resource control under the fidelity and energy constraints, we present a resource increase and decrease algorithm called Early Increase/Early Decrease (EIED) that tries to adjust the effective channel capacity quickly to the incoming traffic volume in an energy-efficient manner, thereby increasing the fidelity (or accuracy) level observed by the application during congestion. Under the framework of energy-constrained optimization, we prove this algorithm incurs the lowest overhead of energy consumption for the given fidelity level that is required by the application.
