This paper discusses the enhancement of security in general purpose operating systems, especially related to threats caused by internetworking, using extensions to operating systems. Such mechanisms have a significantly larger basis for reaching security policy decisions than older host-level security mechanisms and firewalls. By layering defensive mechanisms yet enforcing a consistent security...

Adaptive applications are a key concept to take into account when dealing with multimedia internetworking in wireless and mobile environments, in which network conditions may change abruptly and not always due to congestion –as it happens in fixed networksbut also to interference, mobility and so on. This paper presents an adaptation architecture which allows applications to minimize the impact...

In this paper, we investigate high-capacity fiber-optic networks for real-time telemetry applications. The network topologies and related network components are analyzed for telemetry fiber-optic Local Area Network (LAN) and Metropolitan Area Network (MAN) as well as MAN internetworking with LANs. Two types of multiplexing techniques, namely, Wavelength Division Multiplexing and Time Division M...

This article describes an approach to the design of control planes for optical crossconnects which leverages existing control plane techniques developed for MPLS traffic engineering. The proposed approach combines recent advances in MPLS traffic engineering control plane constructs with OXC technology to provide a framework for real-time provisioning of optical channels, foster development and ...

Scalability in reliable multicast communications is a primal requirement, since there is a large growth of distributed applications based on internetworking with global dimensions. This paper proposes a priority scheme applied to three reliable multicast protocols, resulting in diierent generic models and performance evaluation for these models is established. The results show that the priority...

The G-Lab project aims to investigate new networking paradigms and algorithms for a future internetworking architecture in an experimental manner. Thus the G-Lab project consists of a spiral process of two major fields of activities: research studies of future network components and their experimental design within an experimental facility. Both activities are controlled by the same community t...

This Fourth-generation wireless networks may require an integration of mobile ad hoc networks (MANET) into external network to enhance the flexibility of the communication and roaming. This phenomenon is well-suited for commercial and military applications which yield additional benefit of roaming. However, integration of MANET with external network poses a serious security challenge for commun...

We present the design, implementation, and evaluation of Mobile*IP, a set of IP-based protocols and mechanisms to support host mobility throughout the Internet. The design requires changes only in the mobile hosts and their special routers; leaves transport and higher protocols unaffected, and requires no changes in the device drivers for individual interfaces. No modifications whatsoever are n...

Mobile Ad-Hoc networks(MANET) using Bluetooth technology has gained immense popularity among the networking community. Nowadays electronic devices like cell phones come equipped with Bluetooth. Whereas Bluetooth technology has certain obvious advantages like low power consumption and reliable connection but it suffers some inherent problems including low area of operation, limit of 7 slave devi...
