Design and Implementation of Disaster Aware Routing Protocol to Large Scale Disaster Network

Abstract

Disaster resilient Network is an open issue in routing research as it occurs due to data loss and communication link disturbance in the Mobile Adhoc Network during natural disaster. The Disaster management scheme can be supported with advancement in information and communication technology (ICT) as it gains high popularity and significant research has been devoted to support loss less communication. To achieve the disaster recovery, the solution should be reliable and fast. In this paper, we propose a Disaster aware routing protocol (DRP) which can be achieved through placement of the service node repositories and replica node generation, with movable and deployable units (MDRU) to enhance the lifetime of the network. The Service node repository is modelled with different configuration of MDRU in clusters to make it as reserved nodes for disaster region. It is used to establish the node in the node failure region from the MDRU clusters to inherit invalid reservation and race condition problems. The disaster region is estimated based on the node density difference, within the bounded space. This constraint is handled by hierarchical clustering mechanism based on QOS theory by monitoring the node's transmission range, network traffic and node weight in order to reduce the node discovery and node deployment time by managing the nodes in terms of power level and bandwidth utilization. It also includes the flexible deployment protocol in order to effectively drive decision making process which capable of adapting self deployment according to different situations in the large scale disaster network. Experimental results prove that system is capable of tolerating the fault, during the natural disaster against the state art of approaches.
