Abstract:
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.
