We daily add more devices and services into existing intelligent home networks. Consequently, various networking standards evolutions being experienced world over have not left home networks behind. These evolutions results in competition and depletion of the available limited resources. Consumers therefore, experience unavailable, unreliable and poor performing network both locally and remotely....
We present the framework for a heterogeneous internetworking service architecture to provide probabilistic quality of service guarantees to short critical messages prior to transmission. The TCP/IP Internet is not suited to bear mission-critical data across administrative domain boundaries with stringent delivery requirements because Border Gateway Protocol obscures network state information. Critical...
IEEE 802.11aa amendment introduces several protocols to increase the robustness of multimedia traffic delivery for multicast destinations. According to the recent investigations Block ACK protocol is the most efficient among them. However, it requires polling to each of the multicast group member which may cause significant overhead in the scenarios with large group size. Compared to the polling based...
The data transmission is not controllable within the networked test system, which would result in poor real-time performance and low data transmission reliability. Those problems would lead to the poor test efficiency and even chaos states in the test procedure because of the loss of critical data. This paper proposed a congestion management method named "PQ+WRR", which can effectively alleviate...
Next-Generation Networks (NGNs) will support Quality of Service (QoS) over a mixed wired and wireless IP-based infrastructure. A relative model of service differentiation in Differentiated Services architecture is a scalable solution for delivering multimedia traffic. However, considering the dynamic nature of radio channels specifically, it is difficult to achieve the target quality provisioning...
The Quality of Service (QoS) in smart grid communications especially in monitoring smart grid assets is becoming significantly important for emerging smart grid applications. Wireless Sensor Networks (WSNs) are expected to be widely utilized in a broad range of smart grid applications due to their numerous advantages along with their successful adoption in various critical areas including military...
Wireless multimedia sensor networks consist of thousands of sensor nodes and one or more sink nodes which are distributed in a geographical area to gather information about physical phenomenon of interest. Nowadays modern motes have many sensors running in them and they sense different physical quantities such as temperature, pressure, light etc. When these sensor nodes are used for monitoring mission...
Future application areas of wireless sensor networks (WSNs) may include industrial process automation, aircraft control systems or patient monitoring in hospitals. Such applications require predictable quality of service in terms of message transfer delay and reliability. Performance of WSN data transport is to a large extent defined by the employed medium access control (MAC) protocol. Currently,...
