Today's Internet uses the IP protocol suite that was primarily designed for the transport of data and provides best-effort data delivery. Thus, it does not guarantee the quality of voice transmission that is highly sensitive to error and delay. The situation is even more severe in wireless networks which experience even more distortion and attenuation. Therefore, enhancing the voice traffic quality...
Overlay routing has emerged as a promising approach to improving performance and reliability of Internet paths. To fully realize the potential of overlay routing under the constraints of deployment costs in terms of hardware, network connectivity and human effort, it is critical to carefully place infrastructure overlay nodes to balance the tradeoff between performance and resource constraints. In...
Our goal is to propose a unified/generalized model for the Wireless Mesh Networks (WMNs) design problem taking into account all the parameters that have a significant impact on WMNs. In the WMNs design literature, different studies take into account traffic demand, interference, multi-channel, transmission power, potential locations of wireless routers/gateways and node's characteristics (number of...
This paper reviews the key requirements for the high-capacity optical transmission that supports the exponential growth of global IP traffic. The requirements include total data rate, transmission distance, flexibility, reliability, and cost.
