原生支持自组织通信技术的移动设备的广泛传播导致了一些用于启用和优化移动自组织网络（manet）的协议。然而，由于缺乏自动创建和发展自组织网络的协议，在现实生活中，manet的实际应用似乎有限。最近，Wi-Fi联盟提出了一种名为Wi-Fi Direct的新型P2P协议，并对其进行了标准化，以方便附近设备的互联。Wi-Fi Direct提供高性能的设备间直接通信，包括不同的能量管理机制，现在在大多数Android移动设备上都可以使用。然而，目前在Android上实现的Wi-Fi Direct有几个限制，使得Wi-Fi Direct网络只能是一个单跳自组织网络。本文旨在开发一种在Android智能设备中使用Wi-Fi Direct的多跳自组织网络的新框架。该框架包括连接建立协议和组管理协议。在omnet++模拟器上进行了仿真验证。我们通过改变传输范围、跳数和缓冲区大小来分析该框架。结果表明，对于不同的传输范围和跳数值，该框架提供了最终100%的数据包传输。缓冲区大小有足够的空间容纳所有数据包。但是，随着缓冲区大小的减小，数据包的发送也会成比例地减少。
The wide diffusion of mobile devices that natively support ad hoc communication technologies has led to several protocols for enabling and optimizing Mobile Ad Hoc Networks (MANETs). Nevertheless, the actual utilization of MANETs in real life seems limited due to the lack of protocols for the auto-matic creation and evolution of ad hoc networks. Recently, a novel P2P protocol named Wi-Fi Direct has been proposed and standardized by the Wi-Fi Alliance to facilitate nearby devices’ interconnection. Wi-Fi Direct provides high-performance direct communication among devices, includes different energy management mechanisms, and is now available in most Android mobile devices. However, the current implementation of Wi-Fi Direct on Android has several limitations, making the Wi-Fi Direct network only be a one-hop ad-hoc network. This paper aims to develop a new framework for multi-hop ad hoc networking using Wi-Fi Direct in Android smart devices. The framework includes a connection establishment protocol and a group management protocol. Simulations validate the proposed framework on the OMNeT++ simulator. We analyzed the framework by varying transmission range, number of hops, and buffer size. The results indicate that the framework provides an eventual 100% packet delivery for different transmission ranges and hop count values. The buffer size has enough space for all packets. Howev-er, as buffer size decreases, the packet delivery decreases proportionally.
