Recently, it has been well discussed and proposed that unmanned aerial vehicles (UAVs) are operated as an adhoc wireless mesh network infrastructure that connects isolated areas to a communication infrastructure. However, the prior researches did not consider the following assumptions. First, wireless access points (APs) can be separable from UAVs and carried by UAVs. UAVs do not need to keep flying, once APs are placed at right positions for connectivity. Second, UAVs' and APs' batteries can be replaceable and carried by UAVs. They do not need to wait at the energy-supplying station until their batteries are fully charged. The recent development of mechanical automation for UAVs has been making these assumptions realistic. In this paper, therefore, we propose a new design of wireless multihop networks formed by UAVs on the assumption that batteries and APs are replaceable and separable from UAVs and both are carried and placed to the right positions by the mechanical automation of UAVs. This paper also shows possible design options of the UAV-formed multihop networks and the comparison between them. The simulation results validate the feasibility of each design model.
