A study on the performance of TCP Vegas versus different TCP variants in homogeneous and heterogeneous wired networks are performed via simulation experiment using network simulator (ns-2). This performance evaluation prepared a comparison medium for the performance evaluation of enhanced-TCP Vegas in wired network and for wireless network. In homogeneous network, the performance of TCP Tahoe, ...

Hybrid fieldbus network integrating wireless networks with existing wired fieldbuses has become new a research direction in industrial automation systems. In comparison to wired fieldbuses, the hybrid wired/wireless fieldbus network has a different system architecture, data transmission mechanism, communication protocol, etc. This leads to different challenges that need to be addressed. This pa...

The widespread usage of internet application through wireless medium along with the wired medium has made the internet server to be one for combined wired and wireless network. The criteria for adapting intrusion detection in wireless scenario are different from the traditional wired intrusion detection. The wired network routing and data transmission lies in the standard physical routing. Howe...

Problem statement: Wireless LAN IEEE 802.11 protocols are growing rapidly and security has always been a concern with the security of wired network. Wireless networks encountered threats from unauthorized access to network resources, installation of access points and illegal sniffing (refer as classical intrusion threats). In its current hybrid wired and wireless network attacks on the generall...

Attacks on wireless networks can be classified into two categories: external wireless and internal wired. In external wireless attacks, an attacker uses a wireless device to target the access point (AP), other wireless nodes or the communications on the network. In internal wired attacks, an attacker or authorized insider inserts an unauthorized (or rogue) AP into the wired backbone for malicio...

Computer networks can be built using either wired or wireless technology. Although wired network has been the traditional choice, wireless technologies are becoming more popular. One of the most challenges is to have an existing wired network to which a wireless network extension could be added. Specifically the challenge is to connect a group of wireless networks through a wired backbone. The ...

–Very large scale integration of complex circuits on to a smaller chip demands for the evolution of high speed computer networks. The traditional wired network constraints like mobility and expensive cabling. But wireless communication is a flexible data communication system implemented as an extension to or as an alternative for wired communication. The bandwidth and the services provided by t...

We consider a heterogeneous (also called “hybrid”) ad-hoc network with wired and wireless links. This type of network was previously considered by Kulkarni and Viswanath in [9] where achievable transport capacity growth rates were demonstrated for a structured wired infrastructure. The present paper improves on this work by demonstrating that efficiency can be increased significantly if the wir...

Sensor and actor networks are used to monitor and control pipeline infrastructures. This paper discusses and compares different sensor and actor network architectures for water, gas, and oil pipeline infrastructures monitoring. These architectures are wired networks, wireless networks, separated wired and wireless networks, and integrated wired and wireless networks. The paper also discusses th...
