Designing wireless sensor networks should meet appropriate parameters such as quality of service (QoS) defined by different users. The variable physical conditions of the environment, processing and transmission power limitations and limited communication capabilities are the most important obstacles that influence QoS parameters such as throughput, delay, reliability and network lifetime. The ...
In networked control systems, the varying transmission time delay of the transmitting signal is unavoidable. If the varying transmission time delay exceeds the fixed sampling time, the system will be unstable. To solve this problem, in this paper, the logicbased fuzzy neural networks are applied to the prediction of transmission time delay. The predicted time delay is used as a sampling period ...
VANETs, as a subset of the MANETs, have progressed remarkably in recent years. These networks have an important role in improving traffic, road safety and driver service. In vehicle Networks, vehicle can Communication by vehicle-to-vehicle communication. Since there are fewer vehicles in the environment, there is no vehicle-to-vehicle connection in some areas. Therefore, they use Road Side Unit...
Also, the power-handling capacity of a transmission line is maximum when it is "flat", i.e., operating at low SWR. Lastly, it is important to be able to interconnect a number of different components into a system, and the only way that can be done reliably and predictably is by constraining the reflection coefficients of the various interfaces through impedance matching. Multiple reflections ca...
For wireless data traffic, energy efficiency can be improved by adapting the transmission power and rate over time based on the offered traffic as well as any channel state information. In this context, a variety of transmission scheduling approaches have been studied including [1, 2, 3]. These approaches attempt to manage the fundamental trade-off between packet delay and transmission power or...
Since the packet is transmitted to a set of relaying nodes in opportunistic routing strategy, so the transmission delay and the duplication transmission are serious. For reducing the transmission delay and the duplicate transmission, in this paper, we propose the delay based duplication transmission avoid (DDA) coordination scheme for opportunistic routing. In this coordination scheme, the cand...
introduction: pulmonary tuberculosis is major problem worldwide and it is estimated one third the world population are already infected and each year 9 million people develop full blown tuberculosis of these 3 million die of the disease, annually. delay in diagnosis and treatment are major problems that play a significant role in all aspect of the disease from patient treatment to transmission ...
