We offer an analytical solution for the optimal frame size of the non-muting version of the Basic Frame Slotted ALOHA collision resolution protocol for RFID networks. Previous investigations of RFID frame size have been empirical and have not yielded a general result. Our theoretical analysis provides a generalized result. Our solution can be used to(More)
We investigate methods of using CRC32 for compressing Web URL strings and sharing of URL lists between servers, caches, and URL switches. Using trace-based evaluation, we compare our new CRC32 digesting method against existing Bloom filter and incremental CRC19 methods. Our CRC32 method requires less CPU resources, generates equal or smaller size digests,(More)
Radio Frequency Identification (RFID) networks use radio signal broadcast to automatically identify items with attached RFID tags. A tag consists of a microchip that stores a unique identifier and an antenna. The tag’s antenna is attached to the chip and can transmit a unique tag identifier to a reader (also called interrogator). The reader is capable of(More)
URL, or layer-5, switches can be used to implement locally and globally distributed web sites. URL switches must be able to exploit knowledge of server load and content (e.g., of reverse caches). Implementing globally distributed web sites offers difficulties not present in local server clusters due to bandwidth and delay constraints in the Internet. With(More)
Our study evaluates user (Web browser) accesses to a Web server. We examine a Web server log that was collected for the span of several months at the College of Design, Construction, and Planning in the University of Florida in Gainesville, Florida. We have produced statistics that give us an insight into user access behavior. We were able to isolate cases(More)
Mobile health applications have been found to facilitate earlier and more effective intervention of both physical and mental illness. The applications offer unique opportunities for monitoring progress, providing education materials, receiving personalized prompts and support, collecting ecologically valid data, and using self-management interventions when(More)
