Location-Aware QoE-Driven Wireless Relay Deployment for Energy Efficient Multimedia Communications

In order to support the future quickly deployable wireless multimedia services around mmWave frequency band, a location-aware multimedia relay node deployment (MRND) scheme is proposed in this paper. The self-organized MRND is capable of deploying the multimedia relay Base Station (BS) at the optimal locations in the network and apply optimal resource allocation strategy, to bridge the connections between the multimedia users and the internet gateway. The main contribution of this paper includes two folds. First, a Quality of Experience (QoE)-driven location-aware optimization algorithm of autonomous relay BS deployment scheme is proposed to achieve maximized system level QoE under energy constraints. Second, an adaptive resource allocation strategy is applied to adjust transmission data rate in conjunction to deployment optimization algorithm. Extensive simulation results in terms of the energy utilization and system QoE performance reveal the potential of the proposed self-positioning and rate allocation strategy in the MRNDs as a candidate for future multimedia communications in mmWave band.
