Multi-level Cluster Based Device-to-Device (D2D) Communication Protocol for the Base Station Failure Situation

摘要

With the massive increase of wireless devices and the challenges associated, device-to-device (D2D) communication becomes a vital solution. Employing D2D communication achieves higher throughput, better cell coverage, increases the spectrum efficiency and other valuable benefits for the cellular networks. In this paper, D2D communication is used to overcome the problems occurred in the situation of Base station (BS) failure and maintain the communication inside the cell without BS. An energy efficient multi-level cluster based D2D communication protocol is introduced to maintain the cell operation even if the Base station is out of use. The protocol employs D2D communication and multi-level clustering to provide communication paths through the neighbouring cells and BSs. The proposed work also efficient if there is a catastrophic situation.
