Research on Multi-UAV Networks in Disaster Emergency Communication

Abstract

Abstract Unmanned Aerial Vehicles (UAVs) are an emerging technology that can be used in military, public, and civilian applications. Military use of UAVs is more than 25 years old, mainly for border surveillance, reconnaissance and so on. UAVs can do the job more efficiently and cost-effectively than with a single UAV system. In disaster emergency communications system, UAVs system can be deployed rapidly and its coverage can be dynamically adjusted. It provides network support for disaster site rescue in a timely and efficient manner, and real-time information of disaster scene can be returned to the Rescue center to better rescue the affected people. This dissertation proposed SDN-based disaster emergency UAVs networks to realize the flexible deployment and management of high dynamic dis-aster area networks. Meanwhile, it has a significantly improvement in network lifetime and node switching time comparing with Optimized Link State Routing protocol (OLSR) and Ad hoc On-demand Distance Vector Routing protocol (AODV).
