是否可以连接两个或更多的WiFi直群体？ [英] Is it possible to connect two or more WiFi Direct groups?

问题描述

我目前正在与WiFi的直接（WiFiP2p）的一个项目我工作的实验和想知道是否可以创建群体之间的桥梁，从而将其连在一起？

根据经白皮书通过WiFi联盟发布，它应该是可能的（虽然而P2P规范没有描述的机制这种能力 - 的实现是特定于供应商）。我已经通过互联网看了看，发现了一些答案（这，的这个等），但我觉得没有特别定论。综观Andoid的API并没有帮助，所以尽管

我试图创建方案是具有从一个组一个客户端连接到另一组为好。鉴于4个设备（A，B，C，D），其中A和B是一组，其中A为组所有者，而C和D是用D管理的组中：

• ç连接到A.因此2组已经加入了用C充当桥梁。

这可能吗？

解决方案

请参阅本的链接。据当C连接此链接到一个不再由D.管理组的一个组成员不属于同一组的两个设备无法相互通信。

此外，如果有可能有一个WiFi直接组多组业主，然后他们可以互相他们的小组成员一起同时通信。这是根据它们的白皮书在无线直接可选实现。它说：

  

的Wi-Fi Direct的设备维护多个组成员
  同时：可选

但在Android的实现WiFi的直的情况下，有多个组所有者是不可能的。请参阅 Andrdoid的参考。
它说：

  

一个P2P组由单个组的所有者和一个或多个客户端。

I am currently experimenting with WiFi-Direct (WiFiP2p) for a project I'm working on and wanted to know if one can create bridge between groups, thus joining them together?

Based upon the white paper released by the WiFi Alliance, it should be possible (though "The P2P Specification does not describe the mechanism for this capability – implementation is specific to the vendor"). I have looked through the internet and have found some answers (this, this, etc.) but I feel that none are particularly conclusive. Looking at Andoid's API hasn't helped much either.

The scenario I'm trying to create is having a client from one group connect to another group as well. Given 4 devices (A, B, C, D), where A and B are in a group, with A being group owner, and C and D are in a group managed by D:

• C connects to A. Thus 2 groups have been joined with C acting as a bridge.

Is this possible?

解决方案

See this link. According to this link when C connects to A it is no longer a group member of the group managed by D. Without belonging to the same group two device cannot communicate with each other.

Also if it was possible to have multiple group owners in a wifi-direct group then they could simultaneously communicate with each other along with their group members. This is optional implementation in wifi-direct according to their whitepaper. It says:

Wi-Fi Direct Device maintains membership in multiple Groups simultaneously: Optional

But in case of Android's implementation of wifi-direct, having multiple group owner is not possible. See the Andrdoid's reference. It says:

A p2p group consists of a single group owner and one or more clients.
