Advanced motion vector prediction (AMVP) is one of the most important inter prediction coding tools adopted in the state-of-the-art HEVC coding standard, which does great effect on the coding efficiency. However, the current AMVP design is highly sequential and thus restricts the throughput both on the encoder and the decoder sides. To facilitate the parallel processing and enlarge the throughput,...
Data replication is a well-known strategy to achieve the availability, scalability and performance improvement goals in the data management world. However, the cost of maintaining several database replicas always strongly consistent is very high. The CAP theorem shows that a shared-data system can choose at most two out of three properties: consistency, availability, and tolerance to partitions....
In the Long Term Evolution (LTE) network, buffer overflows often occur in the evolved Node B (eNB) when dealing with the traffic bursts from the wired part due to restricted bandwidth or environmental interferences in the wireless part. In this paper, a novel approach is proposed to protect the buffer from overflow by appropriately controlling the advertisement window to enhance the Transmission Control...
Many research initiatives have started looking into Future Internet solutions in order to satisfy the ever increasing requirements on the Internet and also to cope with the challenges existing in the current one. Some are proposing further enhancements while others are proposing completely new approaches. Network Virtualization is one solution that is able to combine these approaches and therefore,...
The paper analyzes the necessary to partition urban traffic signals into different sub-areas firstly. Then a new optimal model is built and an optimal control algorithm based on sub-area partition is proposed for urban traffic signals. In order to gain minimal delay time of vehicles, HCM2000 is used and famous Robertson model is embedded in the optimization process, which can guarantee the proposed...
Wireless Mesh Network (WMN) has been considered as a key emerging technology to construct next generation wireless communication networks. It combines the advantages of both mobile ad-hoc network (MANET) and traditional fixed network, attracting significant industrial and academic attentions. In WMN, the load balancing becomes a hot topic in enhancing the QoS provision as a load balanced WMN exhibits...
Given a graph and an integer L ?? 0, the beacon placement problem (BPP) asks to find a minimum set B of nodes such that for all edges e, at least one of the two endpoints of e can be reached from some node (called an L-beacon) in B using at most L edges. In particular, it reduces to the vertex cover problem if L = 0. This problem arises from link-monitoring in computer networks. Generalizing the works...
In recently years, Web service composition becomes a new approach to overcome many difficult problems confronted by B2B e-commerce, inter-organization workflow management, enterprise application integration etc. Due to the uncertainty of the Internet and various Web services, the performance of the composed Web service can not be ensured. How to model and predict the performance of the composed Web...
The active beacon based network monitoring tries to estimate the transfer delay of a link e by the difference of round-trip times from a beacon host to the two endpoints of e. For efficiency, we consider the problem of placing a minimum set of beacons to monitor all links of a given TCP/IP network e.g., the Internet. We propose an idea called L-beacon, i.e., a beacon can monitor only links within...
