D2D Communication and Energy Efficiency on LTE for Public Safety Networks

摘要

Communication between rescue teams and people affected by the disaster is of vital importance. However, in the event of a disaster, infrastructures such as roads, bridges, buildings and communication sections can be damaged. Device-to-device communication technology, which allows direct communication between two devices without the need for any infrastructure, such as a base station, is an important solution to overcome the disaster communication problem. In this study, device-to-device communication technology on Long Term Evolution (LTE) for communication after disaster has been presented based on bandwidth and capacity values from point to point on a sample scenario.
