PERFORMANCE INVESTIGATION AND ANALYSIS OF MANET ROUTING PROTOCOLS IN EMERGENCY SITUATION

Abstract

Mobile Ad-Hoc Network (MANET) is categorized by mobile hosts, vibrant topology, multi-hop wireless connectivity and substructure less ad hoc situation. Wireless networking is an emerging technology that will allow users to access information and services regardless of their geographic position. In contrast to infrastructure based networks, in wireless ad hoc networks, all nodes are mobile and can be connected dynamically in an arbitrary manner. All nodes of these networks behave as routers and take part in discovery and maintenance of routes to other nodes in the network. This feature presents a great challenge to the design of a routing scheme since link bandwidth is very limited and the network topology changes as users roam. This thesis investigates the behavior of existing traditional routing algorithms and proposes and rigging a new routing approach for ad hoc wireless networks: Fisheye Routing. Fisheye Routing is similar to Link State routing, but uses a fisheye technique to reduce the consumption of bandwidth by control overhead. When all kind of network and all of the equipment will be destroyed, in this situation we can use Mobile Ad-Hoc network (MANET). MANET has a dynamic topology also there is not any center point for control the network. There has different type of routing protocol in MANET like as AODV, DSDV, DSR, TORA routing protocol.
