They differ from standard network flows by defining edge capacities to be the total amount of flow that can enter an edge in one...

Wireless Sensor Networks (WSNs) are increasingly used in Intelligent Transportation System (ITS) applications, especially in dynamic management of signalized intersections. This paper proposes a Bluetooth network architecture in order to monitor vehicular traffic flows near to a traffic light. The proposed architecture is characterized by a novel algorithm in order to determine green times and ...

The multi-agent-based supply chain network is a dynamic system consisting of multiple subchains connected by information flows, material flows and capital flow, etc. consensus multi-agent systems often applied to the cooperation between inventory management in networks. Considering ubiquitous external disturbances, this paper mainly considers fixed-time stochastic three-echelon system. A nonlin...

Several network flows heuristics have been suggested in the past for the solution of the complementary suppression problem. However, a limited computational experience using them is reported in the literature, and, moreover, they were only appropriate for two-dimensional tables. The purpose of this paper is twofold. First, we perform an empirical comparison of two network flows heuristics. They...

In this paper, we describe a dynamic programming approach to find optimal trees to the singlesource minimum cost network flow problem with general nonlinear costs. This class of problems is known to be NP-Hard and there is a scarcity of methods to address them. The algorithms previously developed have considered only two particular types of cost functions: “staircase” and “sawtooth”. Here, a dy...

We propose STRIDE, a new Internet architecture that provides strong DDoS defense mechanisms for both public services and private end-to-end communication. This new architecture presents several novel concepts including long-term static paths, bandwidth allocation through a top-down topology discovery protocol, dynamic bandwidth allocation via network capabilities, and differentiated packet prio...

Current active queue management (AQM) and TCP protocol are designed and tuned to work well on wired networks where packet loss is mainly due to network congestion. In wireless networks, however, communication links suffer from significant transmission bit errors and handoff failures. As a result, the performance of TCP flows is significantly degraded. To mitigate this problem, we analyze existi...
