Reliability analysis in a wireless ISP
(2023-03-14)
Research report
Open AccessThis brief report investigates different quality parameters to assess the reliability in Wireless Internet Service Providers, WISPs. In our analysis we use a Markov chain approach. We investigate the time to failure, failure ... -
Demonstration of a library prototype to build LoRa mesh networks for the IoT
(2022-02)
Research report
Open AccessLoRa has become popular in the Internet of Things (IoT) domain as a Low Power, Wide Area Network (LPWAN) radio technology providing low-power and long-range communi- cation. In a typical IoT application, the LoRaWAN ... -

(2019-07-26)
Research report
Open AccessResponse of emergency units after natural disasters, such as earthquakes, has to be coordinated, fast and efficient in order to rescue and care for the victims, keeping all the population –and the units themselves– safe ... -
Traffic burstiness influence on ATM switching behaviour
(1989)
Research report
Open AccessTraffic studies is an important subject to evaluate the performance of the switching elements in an ATM environment. The main reason is that ATM cell stream have a variable birate where the maximum peak birate can be several ... -
Bursty cell stream characterization
(1989-01)
Research report
Open AccessTraffic cell stream generated by a single source (or a single connection traffic cell stream) may be characterized by its mean traffic intensity (or normalized mean cell rate) Ai, but also by its burstiness. "Burstiness ... -
