Approaches for Disaster Communication Backbone Network in Operator Independent Scenario

摘要

Communication system performance is very crucial during disaster relief operations. The wireless communication systems are expected to perform at their best in hostile conditions with limited resources since thousands of lives are at stake. Need of communication in disaster, deals with many challenges like Energy/power efficiency, reliable connectivity, availability, throughput, QoS and interoperability, so considering all these aspects, we propose an approach for the disaster communication network through existing Base Station (BS) by optimal selection of BS under the constraint of cell coverage and capacity. Those selected BS can be from any operator and where we install emergency system (ES). Which design to work in operator independent mode on some pre-defined spectrum shared by all the operator and has the flexibility to increase the height according to need through helium balloon as considered by the BLUE-COM+ project. Those ES provides the necessary communication network to the victim and helps the rescue team with effective service at the time of disaster. Simulation result shows that the increment in height of BS through ES can be beneficial in respect to cover the user of blackout area and demonstrate how coverage is related with the number of user and user data rate in a considered band of spectrum.
