The proper adjustment of sleep time in idle mode (a.k.a. DRX-Discontinuous Reception in 3GPP specifications) is critical for mobile device (MD) operation in cellular wireless systems. The dynamic radio environment due to transmission impairments and mobility renders this requirement a nontrivial challenge. Moreover, this issue is aggravated in heterogeneous(More)
A distributed system which comprises independent sensors and a fusion center is considered. Optimum quantization of sensor observations by Chernoff Information (CI) and deflection criterion (DC) for detection purpose is studied. Chernoff information of overall system is derived, and locally optimum quantization of sensor observations is proved to achieve(More)
In large scale distributed sensing systems such as wireless sensor networks (WSNs), Distributed Source Coding Methods can be difficult to apply, due to lack of signal statistics. Distributed Compressive Sensing (DCS) emerges as a cure to this problem. Moreover, the size of the sensor reports on distributed sensing is limited due to bandwidth and battery(More)
LTE technology is considered as the next enabler of the public safety networks with regard of its performance and reliability. The mission critical communication in public safety network requires non-stop connectivity, especially in natural disaster scenarios. To provide further reliability, the eNode-Bs should ensure connectivity when the backhaul(More)
