D2D Communication On LTE For Disaster Management And Emergency Rescue Operations

Many people around the world are adversely affected by various unforeseen disasters such as earthquakes, floods, tsunami, volcanic eruptions etc. Disasters and emergency crisis are usually unpredicted events that cause panic condition in the civilian and affect existing resources. Further to minimize damage caused to civilians and property, efficient rescue operations need to be carried out which needs establishment of reliable communication link. However, during disaster, the existing communication infrastructure may be damaged due to which services may not be available or may be heavily congested. Hence in this paper, novel algorithms have been proposed to extend coverage for partial coverage areas and out of coverage areas (coverage holes) through interworking Long Term Evolution (LTE) system with ad-hoc networks, to enhance Quality of Service (QoS) requirements of disaster area User Equipments (UEs) within cell by deploying micro eNodeB (eNB) near the disaster site which is enabled with Geo-Tagging (GT)-based Connection Admission Control (CAC) mechanism for serving disaster area UEs.
