摘要

提出了一种适用于IEEE 802.11无线单跳无人机网络的精确分组延迟模型。现有的大多数模型都假设网络是一个完整的图，任何数据包的碰撞都将不可避免地导致传输失败，与此不同，我们考虑了一个更实际的部分连接无人机网络，以及一个更现实的接收模型。在马尔可夫链模型的基础上，导出了平均数据包延迟的封闭表达式。评估了网络大小、分组生成速率和初始竞争窗口大小对平均分组延迟的影响。仿真结果验证了分析模型的准确性。

An Accurate IEEE 802.11 Packet Delay Model for Single-Hop UAV Networks

An accurate packet delay model for the IEEE 802.11 wireless single-hop UAV networks is proposed in this paper. Different from the majority of the existing models which assume that the network is a complete graph and any packet collision will inevitably lead to transmission failure, we consider a more practical partially connected UAV network as well as a realistic receiving model. A closed-form expression for average packet delay is derived based on Markov chain model. The effects of network size, packet generation rate and initial contention window size on average packet delay are evaluated. The simulation results verify the accuracy of our proposed analytical model.

期刊介绍： The scope of the Transactions is threefold (which was approved by the IEEE Periodicals Committee in 1967) and is published on the journal website as follows: Communications: The use of mobile radio on land, sea, and air, including cellular radio, two-way radio, and one-way radio, with applications to dispatch and control vehicles, mobile radiotelephone, radio paging, and status monitoring and reporting. Related areas include spectrum usage, component radio equipment such as cavities and antennas, compute control for radio systems, digital modulation and transmission techniques, mobile radio circuit design, radio propagation for vehicular communications, effects of ignition noise and radio frequency interference, and consideration of the vehicle as part of the radio operating environment. Transportation Systems: The use of electronic technology for the control of ground transportation systems including, but not limited to, traffic aid systems; traffic control systems; automatic vehicle identification, location, and monitoring systems; automated transport systems, with single and multiple vehicle control; and moving walkways or people-movers. Vehicular Electronics: The use of electronic or electrical components and systems for control, propulsion, or auxiliary functions, including but not limited to, electronic controls for engineer, drive train, convenience, safety, and other vehicle systems; sensors, actuators, and microprocessors for onboard use; electronic fuel control systems; vehicle electrical components and systems collision avoidance systems; electromagnetic compatibility in the vehicle environment; and electric vehicles and controls.
