A Propose Architecture of MANET for Disaster Area Architecture

Abstract

 Abstract—Wireless ad hoc networks have become an important area of research in wire-less communications systems. Unlike some existing networking technologies such as Internet Protocol (IP) networks or cellular systems, wireless ad hoc networks have the advantage that deployment of networks does not require preexisting infrastructures. Ad hoc networks have neither fixed topology nor centralized servers; it is assumed that, once deployed, the network nodes would self-configure to provide connectivity and form a communications network. Communications are vital for effective management and execution of disaster response and recovery efforts emergency response personnel must be able to exchange information with each other from anywhere, at any time, to successfully fulfill their missions. The National Communications System (NCS) has initiated an effort to improve communication capabilities by first identifying the full range of communication requirements within the disaster area. The NCS has interviewed disaster response managers with experience in the most recent occurrences, to learn specific communication and information system requirements are most critical. A Disaster Area Architecture was designed to meet these requirements. The so-called emergency communications at the time of catastrophic disaster etc. is considered to use ad hoc network effectively. Therefore, it is important to configure emergency communications networks that offer required sufficient QOS in disaster conditions using ad hoc networks. We arrange information and communication required after a disaster from the viewpoint of time elapsed since the disaster. We propose a possible practical communication model for developing ad hoc network configuration technologies.
