Abstract: The conventional border patrol systems suffer from intensive human involvement. Recently, unmanned border patrol systems employ high-tech devices, such as unmanned aerial vehicles (UAVs), unattended ground sensors, and surveillance towers equipped with camera sensors. These nodes rebroadcast the received beacon until it reaches all UAVs in the network. During their propagation, when passing by the UAVs, the beacons carry the identification of the UAVs that relay them. Like this, when a UAVs receives a beacon, it is able to update the list of its neighbors and the distance, in number of hops, to the tail node. The proposed algorithm FANET is used to improve the packet delivery and reduce delay time between sources to destination for UAVs network. In this approach, a node maintains the topology information involving its one-hop neighbors. During a reconfiguration process following a path break, improve FANET protocol has the unique property to limit the control packets to a small region of network. The implementation of FANET routing protocols in UAVs networks serves to fulfil the purpose of reservation of sufficient resources along a route so as to meet the QoS requirements of a flow. The FANET can efficiently calculate the communication delay of a packet across an UAVs network is the path selection based on score value and less delay path only selected to send by a packet to reach the destination from the source. The experimental result using NS2.34 simulator and compare the end-to-end latency of a packet at the network layer are processing delay, packetization delay, transmission delay, queuing delay and the propagation delay.
