UAV Energy-Efficient Communication
Research Guide
What is UAV Energy-Efficient Communication?
UAV Energy-Efficient Communication optimizes UAV trajectories, hovering times, and transmission schedules to maximize data throughput under propulsion energy and battery constraints.
Researchers model UAV propulsion power alongside communication power to extend mission durations. Techniques include trajectory optimization, solar recharging integration, and multi-UAV coordination for coverage. Over 20 papers since 2016 address these constraints in civil applications (Shakhatreh et al., 2019; Otto et al., 2018).
Why It Matters
Energy-efficient designs extend UAV mission times for precision agriculture monitoring, reducing battery swaps and enabling continuous remote sensing (Valente et al., 2011). In disaster response, optimized paths minimize propulsion costs while relaying data from ground sensors (Pang et al., 2014). Multi-UAV coordination cuts total energy use by 30-50% in coverage tasks, supporting scalable IoT platforms (Jeong et al., 2017; Hossein Motlagh et al., 2017).
Key Research Challenges
Propulsion-Communication Tradeoff
UAV speed and altitude affect both propulsion energy and link quality, requiring joint optimization. Jeong et al. (2017) formulate bit allocation with path planning under energy budgets. Balancing hovering for transmission against transit costs limits throughput (Shakhatreh et al., 2019).
Battery and Recharging Models
Nonlinear battery discharge and solar recharge complicate scheduling. Pang et al. (2014) use UAVs for wireless charging in harsh terrains, extending sensor life. Real-world variability demands accurate models beyond linear approximations (Otto et al., 2018).
Multi-UAV Coordination Overhead
Scheduling inter-UAV relays increases communication overhead under shared energy limits. Chandrasekharan et al. (2016) design aerial networks with trajectory planning for coverage. Scalability suffers from collision risks and synchronization needs (Cabreira et al., 2019).
