TL;DR: A novel approximate analytical model is described that allows cloud operators to determine the relationship between the number of servers and input buffer size and the performance indicators such as mean number of tasks in the system, blocking probability, and probability that a task will obtain immediate service.

TL;DR: The analysis of Stability of the network queues shows that the stability of the downlink queue at the coordinator is the most critical for network operation, and shows that certain features prescribed by the standard actually limit the performance of 802.15.4 networks.

TL;DR: A blockchain-assisted lightweight anonymous authentication (BLA) mechanism for distributed VFS, which is provisioned to driving vehicles, and achieves anonymity, and granting vehicle users the responsibility of preserving their privacy by effectively combining modern cryptographical technology and blockchain technology.

TL;DR: The results indicate that, in general, TDD has a small positive effect on quality but little to no discernible effect on productivity.

TL;DR: The operation of a personal area network, operating under the IEEE Standard 802.15.4 in the beacon enabled mode, is analyzed using the theory of discrete time Markov chains and M/G/1/K queues to derive several important performance parameters such as probability of access, probability that medium is idle, queue length distribution in the device, and probability distribution of the packet service time.
