It is a major challenge for a detection algorithm to maintain high detection probability and low false alarms simultaneously. In this paper, we propose an adaptive CUSUM algorithm (ACS) to robustly detect an anomaly, which is defined as system behavior that deviates from its expected values. By embedding a sliding model control (SMC) controller into a CUSUM detector, ACS effectively prevents un...

Concerns over the scalability of TCP’s end-to-end approach to congestion control and its AIMD congestion adaptation have led to proposals for router-based congestion control, specifically, active queue management (AQM). In this paper we present an end-to-end alternative to AQM—a new congestion detection and reaction mechanism for TCP based on measurements of one-way transit times of TCP segment...

Many prominent smart contract applications such as payment channels, auctions, and voting systems often involve a mechanism in which some party must respond to challenge or appeal action within fixed time limit. This pattern of challenge-response mechanisms poses great risks if, during periods high transaction volume, the network becomes congested. In this case, fee market competition can preve...

One of the important problems that urban residents suffer from is Traffic Congestion. It makes their life more stressful, it impacts several sides including economy: by wasting time, fuel and productivity. Moreover, psychological physical health. That road authorities required to find solutions for reducing traffic congestion guaranteeing security safety on roads. To this end, detecting users i...

Due to the bufferless nature, TCP over Optical Burst Switched (OBS) networks suffer from false congestion detection, where a packet loss event due to random burst contention in a lightly-loaded OBS network may trigger TCP congestion control mechanisms, thereby degrading the performance of TCP. This phenomenon is particularly serious for the TCP flows with very high bandwidth, where returning to...
