Study Of MANET For Military UAVs

The role of reconnaissance and attack UAV has been increasingly significant in conflicts and wars the US force involved in recent years. In addition to reconnaissance, the US UAV also gradually enforces other operational functions such as attack, command, warning and EW. The US force plans a developing path from single combat to manned/unmanned coordinated operation to UAVs swarming network operation, which implies that the network communication capability of military UAVs will be critical. As a crucial part of the space-air-ground integrated communication in network centric warfare, UAV will exert a significant influence on the future war mode with its incredible networking capability and network performance.A Mobile Ad Hoc Network is a temporary multi-hop network formed automatically by a number of mobile nodes. The decentralizing and self-organizing feature is especially suitable for the coordinated operation of UAVs.With the development of the military UAV technology and the wide deployment of the UAVs, the traditional Ad Hoc routing protocols can no longer meets the requirement of forming a large network which could fits the highly dynamic topological variation and keeps an excellent communication capability. Therefore there is a need to develop a brand-new routing protocol which meets the requirements of the UAV tactical application modeThis paper focuses on the Ad Hoc routing protocol which satisfies large scale,vary speed and heavy traffic load, strives to reduce the routing overhead and make sure the data delay and package delivery rate satisfactory in different application environment. For the above mentioned objectives, the following work has been done by the author:1. The development of military UAV technology and application demands together with the features of UAV networks are analyzed, and the requirements of routing protocols for setting up a military UAV network are proposed.2. We search into the characteristics of different types of typical Ad Hoc routing protocols, analyze the routing overhead and data transmission capability in different application environments, and conclude that the ZRP protocol has great potential for development.3. The improved ZRPBL protocol based on ZRP is proposed. The ZRPBL protocol fulfills zone communication routing based on the location-based concept, which significantly reduces the routing overhead and meanwhile guarantees good ZRP protocol performance. Qualnet network simulation software is applied to implement the ZRPBL protocol algorithm. Simulation results are obtained for different demands such as scale adaptability, node moving speed, large data load, and flexible task grouping. The results proves that the ZRPBL protocol improves further the data transmission capability while guarantees the adaptability and flexibility of the ZRP protocol.4. A remote location service scheme based on Beidou navigation positioning system is proposed.The scheme doesn’t rely on UAV network and realizes node location enquiry without increasing the network load.
