The aim of this study is to investigate the problems caused by discharge of polluted air from tunnels into the environment with a specific focus on residential areas. In city tunnels, portal or stacks, pollutant management is a big challenge. Nowadays, air quality management, particularly in urban tunnels, is considered as a part of the ventilation system design. The goal is to see the environm...

In the recent computing network environment based on reliability and data availability data availability plays a vital role in Network environment. Traffic Management(TM) is widely used in distributed network environment to reduce access cost and improve data availability [5],[6]. It also focuses in maintaining the effective availability of data and maintaining the reliability of data. This pap...

We address the problem of integrating real-time fault-tolerance mechanisms into peer-to-peer systems, with specific architecture and deployment constraints. For this purpose we implemented a prototype hierarchical peer-to-peer framework in which the leaf peers are sensors that generate different kinds of traffic such as mesh management, events, video and audio. We evaluate the framework by meas...

This paper describes a prototype capability for Flow Contingency Management, a component of strategic Traffic Flow Management decision making in the Next Generation Air Transportation System. The Flow Contingency Management concept and associated capabilities described in this paper aim to address current shortfalls in today’s strategic planning process, namely the lack of integrated informatio...
