“…Therefore, the system based on SAND can work in the same way as conventional monitoring systems or in general, conventional live transmission system. However, it still retains the adaptation feature offered by HAS systems [5].…”

The article presents simulation studies of multipath video transmission implemented as a live monitoring system based on adaptive streaming mechanisms. The transmission network consists of the Wi-Fi infrastructure and a single LTE cell. Both wireless networks are used during the operation of the video monitoring system. The analysis of the obtained results allows us to compare the features of two currently used multipath transmission protocols, MultiPath Quick UDP Internet Connections (MPQUIC) and MultiPath TCP (MPTCP) in the context of their use in adaptive video streaming systems. Also, the article contains a summary of the perceived advantages and disadvantages of using several transmission networks simultaneously for the implementation of video surveillance and monitoring systems.

Stochastic dynamic programming (SDP) is an optimization technique used in the operation of reservoirs for many years. However, being an iterative method requiring considerable computational time, it is important to establish adequate convergence criterion for its most effective use. Based on two previous studies for the optimization of operations in one of the most important multi-reservoir systems in Mexico, this work uses SDP, centred on the interest in the convergence criterion used in the optimization process. In the first trial, following the recommendations in the literature consulted, the difference in the absolute value of two consecutive iterations was taken and compared against a set tolerance value and a discount factor. In the second trial, it was decided to take the squared difference of the two consecutive iterations. In each of the trials, the computational time taken to obtain the optimal operating policy was quantified, along with whether the optimal operating policy was obtained by meeting the convergence criterion or by reaching the maximum number of iterations. With each optimization policy, the operation of the system under study was simulated and four variables were taken as evaluators of the system behaviour. The results showed few differences in the two operation policies but notable differences in the computation time used in the optimization process, as well as in the fulfilment of the convergence criterion.
