As a new networking topology, Wireless Mesh Networks (WMNs) have advantageous properties in terms of robustness, range extension and density, but also have significant potential disadvantages, which determines some classical load-balancing algorithms are not very suitable for WMNs. In this paper, we propose a novel load-balancing algorithm to improve the networks performance. The new scheme, which...
For MAC (Media Access Control) protocol not providing QoS(Quality of Service) guarantees. With the increase of multimedia sevices in wireless networks(for example:voice, video, etc), when the networks get crowded, real-time applications will decrease its performance. We proposed a wireless network algorithm for 802.11e, witch supports fixed nodes and mobile nodes, and also swiches and new connections...
For real-time multimedia communication has strict QoS (Quality of Service) requirements for network, especially it is very sensitive to packet loss rate and delay jitter. When the communication network becomes seriously congested, a Bi-directional Resource Reservation model solution is proposed. This scheme supports the QoS priority and Bi-directional Reservation. The results show that the internal...
As a new networking topology, Wireless Mesh Networks (WMNs) have advantageous properties in terms of robustness, range extension and density, but also have significant potential disadvantages, which determines some classical routing algorithms are not very suitable for WMNs. In this paper, we propose a novel routing algorithm based on the WMNs access scheme design to improve the networks performance...
In order to solve the problems that the process of the evolution is only in one step and the investment in network is so costly when the network in nowadays evolutes to NGN(Next Generation Networking), this paper has get a deep research about the soft switch, media gateway control protocol, access gateway and media server and such kind of technology and then submit a kind of design methodology, through...
An estimation suited for network VBR (Variable bit rate) service parameters in the ATM(asynchronous transfer mode) network In order to guarantee the quality of service in the ATM network effectively satisfied userpsilas request, this paper proposed a new kind of method to estimate the service parameters in the VBR ON/OFF source model. According to different service parameters, this method could satisfy...
In view of bandwidth requirements in ATM (asynchronous transfer mode) network, a kind of dynamic bandwidth allocation scheme has been proposed. It solves the problem of low bandwidth utilization ratio caused in VBR (variable bit rate) MPEG (Moving Picture Experts Group) video transmission, the simulation experiment curve indicates that with the increase of already bandwidth value, the average cell...
For MPLS VPN (Multi-Protocol Label Switching Virtual Private Network) not suitable for the complex business logic and application with high security requirements because of its lack of providing encryption and certification, a scheme of enhancing MPLS VPN QoS is proposed. It uses the method based on "Log-infinitely Divisible Cascades", realizes fine-grained security service strategy by integrating...
