—In distributed computing systems (DCSs) where server nodes can fail permanently with nonzero probability, the system performance can be assessed by means of the service reliabil...
We present the results of a performance evaluation of link layer error recovery over wireless links. Our analysis is based upon a case study of the circuit-switched data service i...
Abstract. Recent experimental studies have shown that radio links between low-power devices are extremely unreliable. In particular, the instability and unpredictability of low-pow...
