“…. PINK [15,16] is another method that acts on gateways by changing the value of W r of ACK segments. To operate, the method requires the number of active flows, the RTT of each one, and the transmission channel bandwidth.…”

“…e use of these techniques has the following advantages: it does not require any modification in the TCP implementation at the sides and does not have to be present in routers in the end-to-end path, and its installation in the gateway is sufficient. e use of network-return techniques has been shown to be promising in the control of congestion, as verified in several papers [12][13][14][15][16][26][27][28]. However, a large part of the published studies was limited to a few experiments.…”

“…Problems occur because of the constant dispute over gateway resources, which leads to degradation of throughput, fairness, and delays. In this context, to improve TCP performance, several proposals have been developed that can be grouped into active queue management (AQM) [2][3][4], TCP side changes [5][6][7], AQM + TCP [8][9][10][11], and network-return techniques [12][13][14][15][16]. e use of active queue management is intended to avoid the occurrence of congestion through drop/mark (explicit congestion notification (ECN)) of segments before filling the gateway queue.…”

In the absence of losses, TCP constantly increases the amount of data sent per instant of time. This behavior leads to problems that affect its performance, especially when multiple devices share the same gateway. Several studies have been done to mitigate such problems, but many of them require TCP side changes or a meticulous configuration. Some studies have shown promise, such as the use of gateway techniques to change the receiver’s advertised window of ACK segments based on the amount of memory in the gateway; in this work, we use the term “network-return” to refer to these techniques. In this paper, we present a new network-return technique called early window tailoring (EWT). For its use, it does not require any modification in the TCP implementations at the sides and does not require that all routers in the path use the same congestion control mechanism, and the use in the gateway is sufficient. With the use of the simulator ns-3 and following the recommendations of RFC 7928, the new approach was tested in multiple scenarios. The EWT was compared to drop-tail, RED, ARED, and the two network-return techniques—explicit window adaptation (EWA) and active window management (AWM). In the results, it was observed that EWT was shown to be efficient in congestion control. Its use avoided losses of segments, bringing expressive gains in the transfer latency and goodput and maintaining fairness between the flows. However, unlike other approaches, the most prominent feature of EWT is its ability to maintain a very high number of active flows at a given level of segment loss rate. The EWT allowed the existence of a number of flows, which is on average 49.3% better than its best competitor and 75.8% better when no AQM scheme was used.

A Seismic Alert System (SAS), also called Earthquake Warning System (EWS) or Earthquake Early Warning System (EEW or EEWS), represents one of the most important measures that can be taken to prevent and minimize earthquake damage. These systems are mainly used to detect P-waves and the faster seismic waves and to subsequently trigger an alarm about the incoming S-waves, the slower and most dangerous seismic waves. In some cases, distributed systems are also able to alert some locations before the impending P-waves strike them. This paper presents Earthcloud, a cloud-based SAS that aims to provide all the former capabilities while retaining financial accessibility. Earthcloud first results, generated from four months of data acquisition, are compared with those coming from other systems. In particular, the paper focuses on processing and communication delays, showing how the Earthcloud new detection strategy may minimize delays. Although a thorough test campaign with more sensor nodes is needed to assess performance reliably, especially for highly dense urban scenarios, initial results are promising, with total latencies for Earthcloud always kept under the 1-second mark, despite being at the expense of solid magnitude estimation.
