Recently, designing an effective routing protocol is challenging for flying ad-hoc networks (FANETs) due to the versatile nature of unmanned aerial vehicles (UAVs). Position-based routing schemes are seen to be a remarkable preference for routing in FANETs due to the fact that the geographical information of UAVs is readily available. In this paper, we are interested in the modification of the location-aided routing (LAR) that we call 3D cone shaped location-aided routing (3DC-LAR) a position-based routing (PBR) protocol. In the existing LAR scheme, a route discovery process done through the concept of request zone, in which only nodes presents in the request zone will forward the route request for transmitting the data. The proposed 3DC-LAR scheme modified the definition of request zone using 3D cone shape by intermediate UAVs in FANETs environment. The simulation results reveal that the proposed 3DC-LAR scheme has contributed to lead to an improvement in the terms of routing overhead.

最近，由于无人飞行器（UAV）的通用性，设计有效的路由协议对于飞行自组织网络（FANET）具有挑战性。基于位置的路由方案被认为是FANET中路由的一个显着优先选择，这是因为无人机的地理信息很容易获得。在本文中，我们对位置辅助路由（LAR）的修改感兴趣，我们将3D锥形位置辅助路由（3DC-LAR）称为基于位置的路由（PBR）协议。在现有的LAR方案中，路由发现过程是通过请求区域的概念完成的，其中仅请求区域中存在的节点将转发路由请求以传输数据。提出的3DC-LAR方案通过FANETs环境中的中间UAV使用3D圆锥形修改了请求区域的定义。仿真结果表明，提出的3DC-LAR方案有助于提高路由开销。
