This paper presents a new neural network based approach to the prediction of mobile locations using signal strength measurements in a simulated metropolitan area. The prediction of a mobile location using propagation path loss (signal strength) is a very difficult and complex task. Several techniques have been proposed recently mostly based on linearized, geometrical and maximum likelihood meth...

This paper discusses the possibility of, and provides the conceptual schema for, a wide area network of hospital information systems in the Delhi metropolitan area. Based on an empirical investigation of the pressures on the health care system in the Delhi metropolitan area, we feel that given the existing resources, a well designed and coordinated information system will enable the health care...

The conventional Mobile Ad hoc Network (MANET) is composed of mobile nodes without any infrastructure supporting. But, emergent traffic such as real-time positioning by using wireless infrastructure is indeed required. Therefore, a deployment for mobile ad hoc network would associate WiMax with WiFi which is called 802.16e MANET Environment in this paper. Based on the 802.16e MANET environment,...

All-optical networks that employ wavelength division multiplexing (WDM) are an attractive architecture for future high-speed networks. Through WDM, multiple channels are created on a single fiber, and an aggregate network bandwidth far greater than the peak electronic processing speed can be realized. This paper provides a review and an extensive bibliography of proposed media access control (M...

The overall goal of this study is to forecast both toll revenues and operational impacts associated with congestion pricing strategies, alone or in conjunction with other operational measures. This project showcases the integration of an Activity-Based Model (ABM) and Dynamic Traffic Assignment (DTA) tool in one coherent modeling framework for implementation and evaluation of congestion pricing...

This paper proposes a Carrier Sense Multiple Access with Carrier Preemption (CSMA/CP) MAC protocol for the DWDM Metropolitan Area Network (MAN) Access ring networks. In the network, each node is equipped with one tunable transmitter and multiple fixed receivers. This protocol provides variable size IP packets directly over all-Optical DWDM MAN ring networks and gives the more efficient bandwidt...

WiMAX is an effective metropolitan area broadband access technology, supplying wireless coverage over an area of several kilometers with high data rates. WiMAX technology has introduced WiMAX broadband to provide an alternative to the high cost of broadband connection through cable or DSL. In this paper, simulative investigations have been done for the WiMAX network using different path loss mo...

Wireless mesh networks (WMNs) consist of mesh routers and mesh clients, where mesh routers have minimal mobility and form the backbone of WMNs. They provide network access for both mesh and conventional clients. The integration of WMNs with other networks such as the Internet, cellular, IEEE 802.11, IEEE 802.15, IEEE 802.16, sensor networks, etc., can be accomplished through the gateway and bri...
