Abstract

 Crises management is a challenging problem for homeland security. The challenging aspect in crisis management is the early assessment of needs and damages. The existing approaches are quite unstructured in nature which results in poor resource management and hence inefficient. In this paper, the architecture for reliable and real time approach by using sensor clusters has been proposed for storage management. Instead of storing information in an individual cluster head as suggested in some approaches, storing of information of all clusters, inside the cell is recommended within the corresponding base station. It is assumed that the sensor nodes are aware of their locations in their deployment area, and they are time synchronized. For data dissemination and action in the wireless sensor network the usage of Action and Relay Stations (ARS) has been proposed. In the designed model sensor nodes are deployed prior to a crisis and the sensed information is stored. In case of emergency stored information is queried to get the report of humans trapped under rubble. It is also used to set the objectives and policies for emergency assistance.
