Video streaming data acquired by Unmanned Aerial Vehicles is an innovative service that will be leveraged by several applications ranging from entertainment and surveillance to disaster recovery. 360 cameras provide unprecedented visual information and enable services to a novel level of immersive experience. However, 360 video sources are not still fully characterized, and this holds especially true for drone mounted 360 video sources.

We investigate the problem of providing a video streaming service to mobile users in an heterogeneous cellular network composed of micro e-NodeBs (eNBs) and macro e-NodeBs (MeNBs). More in detail, we target a cross-layer dynamic allocation of the bandwidth resources available over a set of eNBs and one MeNB, with the goal of reducing the delay per chunk experienced by users. After optimally formulating the problem of minimizing the chunk delay, we detail the Cross LayEr Video stReaming (CLEVER) algorithm, to practically tackle it.

In this paper, we apply the recent MPEG-DASH SAND standard for streaming-aware networking elements to develop and investigate an integrated mobile network bandwidth management and resource allocation mechanism. It is used to achieve high quality of experience of the mobile streaming users while jointly assuring high revenue operations by the network operator and by the system's video service providers.
