A mobile wireless sensor network owes its name to the presence of mobile sink or sensor nodes within the network. The advantages of mobile WSN over static WSN are better energy efficiency, improved coverage, enhanced target tracking and superior channel capacity. In this paper we present and discuss hierarchical multi-tiered architecture for mobile wireless(More)
In this paper, we present a model for fuzzy logic based congestion estimation within a proposed QoS architecture. The architecture comprises of a QoS management and control module which is implemented both at node level and at the sink for a system level QoS administration. The QoS module implemented at sensor node forms a subset of the larger QoS(More)
An actinomycete, designated MS426T, the culture broth of which showed potent antimicrobial activity, was isolated from a deep-sea sediment sample of the South China Sea. An almost-complete sequence of the 16S rRNA gene of strain MS426T was determined and aligned with those of representatives of the family Micromonosporaceae available in public databases.(More)
In the course of a screening program for bioactive compounds from a marine natural product library, a newly isolated Actinomycetes strain, designated as MS100061, exhibited strong anti-Mycobacterium bovis Bacillus Calmette–Guérin (BCG) activity. The strain belongs to the genus Streptomyces according to its morphological and 16S rDNA phylogenetic analysis.(More)
Candida albicans, one of the pathogenic Candida species, causes high mortality rate in immunocompromised and high-risk surgical patients. In the last decade, only one new class of antifungal drug echinocandin was applied. The increased therapy failures, such as the one caused by multi-drug resistance, demand innovative strategies for new effective(More)
A Gram-positive, aerobic, non-motile actinobacterium, designated strain Ms392A(T), was isolated from an ocean-sediment sample collected from the South China Sea. The isolate contained chemical markers that supported chemotaxonomic assignment to the genus Amycolatopsis. On the basis of an analysis of 16S rRNA gene sequence similarities, strain Ms392A(T)(More)
An Aspergillus versicolor isolated from sediment collected from the Bohai Sea, China, yielded the new dimeric diketopiperazine brevianamide S (1), together with three new monomeric cometabolites, brevianamides T (2), U (3), and V (4). Structures were determined by detailed spectroscopic analysis. Brevianamide S exhibited selective antibacterial activity(More)
The present study demonstrates the production and properties of a biosurfactant isolated from marine Streptomyces species B3. The production of the biosurfactant was found to be higher in medium containing sucrose and lower in the medium containing glycerol. Yeast extract was the best nitrogen source for the production of the biosurfactant. The isolated(More)
