Sensor nodes are typically battery-powered. As a result, maximizing the network lifetime is an important optimization objective in the design of a WSN (Wireless Sensor Network). In time-critical WSNs, it is important to minimize the maximum latency in data collection. We investigate the problem of lifetime and latency aware data collection in WSNs with one(More)
WSN (Wireless Sensor Network) has a wide range of applications. As a result, security problems become increasingly important. We investigate the problem of minimising the failure rate of packet delivery in the presence of the modification attacks and the selective forwarding attacks in a static WSN with one base station without using expensive(More)
FK506 binding proteins (FKBPs) are intracellular receptors of the immunosuppressant FK506 and play important roles in the correct folding of new proteins and the self-assembly of biological macromolecules. FKBP12 is a member of the FKBP family that is widely expressed and highly conserved in many species. In this study, we identified the complete cDNA(More)
Wireless Sensor Networks need to be organized for efficient data collection and lifetime maximization. In this paper, we propose a novel routing structure, namely k-DAG, to balance the load of the base station's neighbours while providing the worst-case latency guarantee for data collection, and a distributed algorithm for construction a k-DAG based on a(More)
Channel-dependent scheduling of transmission of data packets in a wireless system is based on measurement and feedback of the channel quality. To alleviate the performance degradation due to simultaneous multiple imperfect channel quality information (CQI), a simple and efficient packet scheduling (PS) algorithm is developed in downlink LTE system for real(More)
