Abstract :
Unmanned air vehicles (UAVs) can improve better network performance for ground-based wireless MANETs (mobile ad hoc networks). In this paper, we consider a typical scenario of a MANET with a UAV as the relay node and ground nodes can both connect with the UAV and other ground nodes. We study how to improve the network connectivity and network throughput of the network. By formulating the mobility strategy of the UAV as an optimization problem, we propose an LP-WCTUS (Load and Priority Weighted Center Track Update Strategy) algorithm. Simulation results show that the LP-WCTUS has better network performance comparing with existing CCTU (Center-based Cooperative Trajectory Update), static and random walking strategies.
