For more than three decades, the Virtual Local Area Network (VLAN) has been one of most popular systems virtualization groups users on both local and corporate networks. Because advantages that VLAN provides, network managers operators have continued to use it in creation their networks even extended its include cloud computing networking. Previous research studies established a lot issues asso...

Many recent studies on network traffic demonstrate that Longrange Dependence (LRD) is a ubiquitous property of traffic both in a local area network (LAN) and a wide area network (WAN). So the performance of network should be dominated by this property. Packet Round-trip Delay is an important measurement of network performance. In this paper, we present evidence that LRD exists in packet round-t...

In this paper we propose the ATOM (Adaptive Transport over Multipaths) architecture to enable real-time communications in Wireless Mesh Networks (WMNs). WMNs provide robust communication facilities which are even available when certain other systems fail. On the other hand, real-time applications (e.g., IP telephony, video conferencing) in WMNs suffer from transmission errors, high delays, etc....

Researchers and vendors are expressing a growing interest in 4G wireless networks that support global roaming across multiple wireless and mobile networks—for example, from a cellular network to a satellite-based network to a high-bandwidth wireless LAN. The 4G mobile system is an all IP-based network and provides the user access to different radio access technologies. In this environment, roam...

Providing reliable and efficient communication under fading channels is one of the major technical challenges in wireless sensor networks (WSNs), especially in industrial WSNs (IWSNs) with dynamic and harsh environments. Reliable Reactive Routing Enhancement (R3E) to increase the resilience to link dynamics for WSNs/IWSNs. R3E is designed to enhance existing reactive routing protocols to provid...

Recently, people have begun to use OS virtualization as a tool for improving LAN security. While virtualization is very useful in optimizing hardware utilization, we show that its security benefits come at a price.

In Local Area Networks (LAN) connected together by bridges, flow control and smooth traffic in the network is very important. However, congestion at bridges can cause intensive loss of received frames. In addition, the received frames are thrown away and have to be retransmitted by the source station, which causes more congestion and massive reduction in the overall network throughput. The netw...

Wireless mesh networks (WMNs) promise to increase high-speed wireless property on the far side what's attainable with the present WiFi-based infrastructure. However, their distinctive field options leave them notably prone to security threats. During this article, we tend to describe numerous varieties of refined attacks launched from adversaries with internal access to the WMN. We tend to any ...

Ethernet today is the dominant technology in local area networks. The IEEE 802.3 working group is finalizing an amendment to the Ethernet standard called 802.3ah that will bring Ethernet to the access network. This paper introduces the new features introduced by 802.3ah as well as discusses the potential role of Ethernet in the access network.
