Subband adaptive filter algorithms are able to improve the convergence behavior by performing the prewhitening procedure on the input signals. In this paper, we propose a new variable step size improved multiband-structured subband adaptive filter algorithm which dynamically selects subband filters (VSS-IMASF) in order to improve the steadystate performance. The step size is controlled by the estimated...
Accurate and efficient network-wide traffic measurement is crucial for network management. Recently, Software-defined networking (SDN) has opened up new opportunities in network measurement and inference. In this work, we demonstrate an efficient flow measurement and inference framework which performs adaptive measurement with online learning. Using the reprogrammability of SDN, we assist network...
Network flow monitoring is a crucial procedure for optimizing the network infrastructure for better application performance or security issue. In this paper, we address the problem of Flow Edge-Monitoring (denoted as FEM), for which we need to find k (k > 0) edges in an undirected graph G = (V, E), so that if we place k flow monitors on these edges to measure the flow along them, we can maximize...
In order to implement the emergency rescue operations effectively, this paper purposes an intelligent maritime search and rescue route decision method which is based on the novel intelligent water drops(NIWD) algorithm. The neighborhood expansion mechanism and the optimal solution emphasizing mechanism are introduced into the original intelligent water drops (IWD) algorithm to avoid premature convergence...
A 3-D dynamic path-planning algorithm based on interfered fluid flow (DA) is proposed for unmanned aerial vehicle (UAV) in dynamic environment. This paper first describes the mathematical modeling of convex obstacles. Then the static algorithm based on interfered fluid flow (SA) is introduced and improved, whose planning path conforms to the general characteristic of phenomenon that running water...
The goal of service composition is to create value-added services which automatically composed of exiting services based on dynamic user requirements. Most research on service composition is based on logical reasoning, and do not consider dynamic services requirements and network status. In this paper we present a novel resource-oriented algorithm. The resource-oriented algorithm integrates service...
The construction of computer Chinese chess game platform creates favorable conditions for the development of discrete event dynamic system theory and provides a good research platform for solving dynamic countermeasure problems in discrete system. This paper analyses the existing problems of computer Chinese chess game, the structure and performance of computer Chinese chess game platform and the...
In this paper, we investigate the utility-based resource allocation problem in OFDMA relay networks with service differentiation, where Rate Constraint (RC) and Best Effort (BE) services are supported. Our objective of resource allocation is to maximize the sum utility of BE service users, while guaranteeing that the utility of each RC service user is equal to one. A joint optimization problem for...
In order to maximize the lifetime of wireless sensor networks, while ensuring the monitoring quality for specific applications, we develop the sleep-wakeup algorithms for the sensor networks. Firstly, for the three-dimensional wireless sensor networks, we formulate the virtual barrier coverage problems. Secondly, the design and implementation of the nodes sleep-wakeup scheduling algorithm, FWP, to...
