In this paper, we address the end-to-end rate optimization problem in a wired-cum-wireless network, where CSMA/CA based wireless LANs extend a wired backbone and provide access to mobile users. The objective is to achieve proportional fairness amongst the end-to-end sessions in the network. Since the network contains wireless links whose attainable throughput is a (non-convex and non-separable)...

Data transmission is the process of transmitting digital information from one device to another over a network. With increasing demand for high-speed data and proliferation connected devices, development advanced technologies networks has become crucial. This paper reviews most commonly used networks, including wired wireless technologies, highlights their advantages limitations.

Multiple sensor-based context inference systems can perceive users’ tasks in detail while it requires complicated recognition models with larger resources. Such limitations make the systems difficult to be used for the mobile environment where the context-awareness would be most needed. In order to design and operate the complex models efficiently, this paper proposes an evolutionary process fo...

Reliable multicast is a powerful communication primitive for structuring distributed programs in which multiple processes must closely cooperate together. In this paper we propose a protocol for supporting reliable multicast in a distributed system that includes mobile hosts and evaluate the performance of our proposal through simulation. We consider a scenario in which mobile hosts communicate...

Multicast communication is a powerful paradigm for structuring distributed programs in which multiple processes must closely cooperate together. In this paper we propose a multicast protocol for a distributed system that includes mobile hosts. Mobile hosts communicate with a wired infrastructure by means of wireless technology. Our solution is flexible and provides several novel features. The s...

In industrial applications, it is necessary to select different types of networks according communication requirements. To meet this requirement, a converged network wired and wireless frequently employed. Notably, fulfilling the end-to-end transmission requirements challenging. As solution, converged-network scheduling methods have proved valuable. paper, method for convergence time-sensitive ...

Multicast is an efficient technique to deliver video content over a network. In this paper, we consider such a multicast system to serve both wireless and wireline users when there is error over the wired network and wireless hop. Since packets are likely to be dropped in the wired networks while bit errors are more likely over the wireless hop, a combination of both packet-level and byte-level...

This paper addresses Quality-of-Service (QoS) improvement in wireless mesh networks (WMNs) with multi-radio multi-channel by applying a novel network coding technique. It is known that network coding over wired networks enables connections at rates that cannot be achieved by traditional routings. However, the properties of wireless networks (e.g., omnidirectional transmissions, destructive inte...
