While each AFH algorithm proposed previously is shown to be efficient, a detailed performance analysis of various AFH mechanisms under realistic resource constraints is yet to be done. In particular, based on our performance study on Bluetooth systems presented in this paper, we have found that the AFH mechanism adopted by IEEE 802.15 task group 2 (TG2) is very sensitive to memory and power limitations. We then propose an interference source oriented adaptive frequency hopping (ISOAFH) approach based on a cross-layer design, in which the baseband layer of Bluetooth considers not only the instantaneous channels condition but also the physical layer transmission characteristics of potential interference sources in determining the hop sequence. In our simulations using detailed MATLAB Simulink modeling, we find that our proposed method is much more robust in that it is insensitive to memory and energy constraints. Indeed, our approach generally achieves a lower collision rate and higher ISM spectrum utilization.","PeriodicalId":198404,"journal":{"name":"7th International Symposium on Parallel Architectures, Algorithms and Networks, 2004.

The amino acid-coupling sequence patterns are defined as any two types of amino acids separated apart by one or more amino acids. We found that there exists significantly different distributions of amino acid-coupling sequence patterns between thermophilic and mesophilic proteomes. For example, patterns favored to form local salt bridges (such as KX/sub n/E) are usually preferred by thermophiles; patterns containing glutamate and valine are usually favored by thermophiles, but only some of them are statistically significant; most patterns containing cysteine appear to occur more in mesophiles, but most of them are statistically insignificant except patterns like CX/sub n/P or CX/sub n/C, which is favored by thermophiles. Though previous studies based on global amino acid compositions indicate that glutamate is one of the most favored amino acids by thermophiles, we found that EX/sub n/T, EX/sub n/H and EX/sub n/Q are statistically significant patterns favored by mesophiles. We also identified sequence patterns that can effectively distinguish between thermophilic and mesophilic genomes. By combining the statistically significant amino acid-coupling sequence patterns (of lowest p-values), we find a good linear relationship between these sequence patterns and the optimal growth temperatures of the genomes.","PeriodicalId":198404,"journal":{"name":"7th International Symposium on Parallel Architectures, Algorithms and Networks, 2004.

Caching is a key technique for improving data retrieval performance of mobile clients, regardless of the data delivery mechanism. The emergence of robust peer-to-peer technologies now brings to reality what we call \"cooperative caching\" in which mobile clients can access data items from the cache in their neighboring peers, thereby adding a new dimension for data caching. This paper studies the system performance of a cooperative caching scheme, called COCA, in a hybrid data delivery environment, and proposes a cooperative cache replacement scheme, called CORE, for mobile systems. The performance of COCA and CORE schemes is evaluated through a number of simulated experiments. The experiment results show that COCA effectively improves the system performance in push-based and hybrid-data delivery environments, especially in a heavily-loaded environment. The results also indicate that CORE can further improve on the access latency and reduce the number of expensive server requests, which consume scarce pull-based bandwidth.","PeriodicalId":198404,"journal":{"name":"7th International Symposium on Parallel Architectures, Algorithms and Networks, 2004.
