In a multiuser multiple-input multiple-output (MUMIMO) system where users are equipped with multiple transmit antennas, user pairing and resource allocation can enormously improve cell throughput by means of spatial multiplexing and multiuser diversity. In this paper, we first establish the optimization problem of user pairing and resource allocation in the uplink of Long Term Evolution Advanced (LTE-A)...
The lack of suitable way to get high-performance router testbed negatively affects the researches of new generation network in the campus laboratory. In this paper, we propose a novel and practical method to achieve high-performance router testbed based on Openflow and Click. This method only needs personal computers and hubs. Then we can get a load-balancing high-performance router testbed, and the...
A kind of management model in the mobile transmission resource management system (short for TRMS) is presented . With this model, the efficiency, expansibility of managing the transmission resource can be improved and the complexity can be reduced.
A dynamic policy based network management scheme is presented for the problem that traditional policies can??t preferably adapt to change of network state. It defined dynamic policy form and appended new module PMA to IETF policy frame to improves the adaptability of policie. Then the application of dynamic policy to allocate resource is presented. By experiment and analysis, it is shown that this...
For the problem of multimedia applications not obtain assuring service immediately after mobile IP handoff we propose dynamic policy and design the dynamic policy scheme of resource management in mobile IP. Based on the prediction information of the mobile node, the mechanism automatically produces dynamic policies to do admission control and to prepare resources before handoff occurs. And then it...
The key issue of peer data management systems (PDMSs) is how to efficiently organize and manage distributed resources in P2P networks to accurately route queries from the peer initiating the query to appropriate peers to avoid network flooding. This paper proposes a semantic-based PDMS model, called R-Chord, by deploying the resource space model above the Chord overlay for uniformly, normally and...
This paper describes the architecture and programming model of a semantic-service-oriented sensor information system platform. We argue that the key to enabling scalable sensor information access is to define an ontology and associated sensor information hierarchy for interpretation of raw data streams. The ontological abstraction allows a sensing system to optimize its resource utilization in collecting,...
