Improving QoS Performance of Multi-radio Multi- channel WMNs by Adopting a Novel Channel Assignment Scheme

The CSMA/CA based random channel access mechanisms in Wireless Mesh Networks(WMNs), IEEE 802.11 DCF and EDCA, are inefficient to eliminate effectively hidden terminal and exposed terminal problems in multi-hop scenarios. In this paper, we propose efficient channel assignment and routing protocols for multi-radio multi-channel (MRMC) wireless mesh networks. These set of protocols are based on La...

Boundary Shear Stress in a Trapezoidal Channel

This paper focuses on a hydraulic radius separation approach used to calculate the boundary shear stress in terms of bed and wall shear stress proposed in a trapezoidal channel. The average bed and sidewall shear stress in smooth trapezoidal open channels are derived after using Guo & Julien (2005) early equations taking a part of an investigation to cover both rectangular and trapezoidal chann...

A Novel Multicast Tree Construction Algorithm for Multi-Radio Multi-Channel Wireless Mesh Networks

Many appealing multicast services such as on-demand TV, teleconference, online games and etc. can benefit from high available bandwidth in multi-radio multi-channel wireless mesh networks. When multiple simultaneous transmissions use a similar channel to transmit data packets, network performance degrades to a large extant. Designing a good multicast tree to route data packets could enhance the...

Improving Streaming Capacity in Multi-Channel P2P VoD Systems via Intra-Channel and Cross-Channel Resource Allocation

Multi-channel Peer-to-Peer (P2P) Video-on-Demand (VoD) systems can be categorized into independent-channel P2P VoD systems and correlated-channel P2P VoD systems. Streaming capacity for a channel is defined as the maximal streaming rate that can be received by every user of the channel. In this paper, we study the streaming capacity problem in multi-channel P2P VoD systems. In an independent-ch...
