In order to ensure proper quality of service for real-time communication in a mobile wireless Internet environment, it is essential to minimize the transient packet loss when the mobile host (MH) is moving between different cells (subnets) within a ...

This poster describes a new approach to host mobility, where the responsibility of maintaining an end-to-end pipe that survives changes to the host network attachment point is moved to the transport layer.

The existing DCF mode of lEEE 802.11 MAC protocol does not suitable for multimedia and QoS-sensitive applications. In this paper, we proposed a novel mechanism based on Deficit Round Robin to calculate various lengths of IFS to support QoS in Wireless ...

Since the approval of the IEEE 802.11b by the IEEE in 1999, the demand for WLAN equipment and networks has been growing quickly. We present a queuing model of wireless LAN (WLAN) access points (APs) for IEEE 802.11b. We use experimentation to obtain the ...

Mobile Internet protocol version 6 (MIPv6) [1] is a proposal for handling routing of IPv6 packets to mobile nodes that have moved away from their home network. We have studied the impact of the basic functionalities of MIPv6 on the performance of TCP ...

Development of customized services by discovering, integrating and executing existing ones (refered to as service composition) has received a lot of attention in the last few years with respect to wired, infrastrutcure based web-services. With the ...

After the vulnerabilities found in the WEP protocol, providing secure wireless network access has been shown to be a complicated task. This paper describes the specification of a two-protocol architecture that provides secure, flexible, and convenient ...

The ELAN-Project is an ongoing research focusing on an awareness based E-Learning infrastructure supporting collaborative work by the technical means of multi-hop ad-hoc networks.

We define "Secure Space" as an enclosed area within which wireless devices can participate in secure group communication. A device is able to join a secure space group by the virtue of its location within the enclosure. The devices communicate with each ...

The IP paging architecture in globally-connected mobile ad-hoc network is presented. Motivated by the energy-efficient design requirement in global-connected mobile ad-hoc network context, we design IP paging support in ad-hoc networks that is ...

Traditionally, voice communication over the local loop has been provided by wired systems. In particular, twisted pair has been the standard means of connection for homes and offices for several years. However in the recent past there has been an ...

In this paper, we propose a hierarchical design methodology for grid access from handheld devices. After determining all user interactions required and technologies available, they are arranged in layers. All functions in a layer are also supported by ...
