RESUMO:
Título: Energy Efficient Video dissemination in Software Defined Unmanned Aerial Networks
Resumo: Collaboration among multiple Unmanned Aerial Vehicles (UAVs) to set up a Flying Ad-Hoc Network (FANET) is a growing trend due to its capacity to support a wide range of application. Applications that work with video transmission in FANETs should always deliver a satisfactory video quality to the users even under influence of network topology changes caused by the energy consumption of UAVs. However, one of the main challenges in FANET is how the impact of limited energy resources of UAVs can be mitigated on the FANET operation in order to monitor the environment for a long period of time. In this sense, it is required UAV replacement in order to avoid the premature death of nodes, network disconnections, route failures, void areas, and low-quality video transmissions. This work proposes a cooperative UAV scheme for enhancing video transmission and global energy efficiency, called VOEI. Based on a Software Defined Network (SDN) paradigm, the VOEI assumes the existence of a centralized controller node to compute reliable and energy-efficient routes, as well as detects the appropriate moment for UAV replacement by considering global FANET context information to provide energy-efficient operations. Based on simulation results, we conclude that VOEI can effectively mitigate the energy challenges of FANET, since it provides energy-efficiency operations, avoiding network death, route failure, and void area, as well as network partitioning compared to state of the art algorithm.
