Can Android do peer-to-peer ad-hoc networking?
提问by Doughy
Is it possible to set up Android in ad-hoc peer-to-peer wifi mode? For example, I would like to have one phone broadcast a message, and have all peers in the network receive the broadcast, without having a server. I would like to use wifi since bluetooth range is more limited.
是否可以在点对点 wifi 模式下设置 Android？例如，我想让一部手机广播一条消息，并让网络中的所有对等方都收到广播，而无需服务器。我想使用 wifi，因为蓝牙范围更有限。

Here's a bug report on the feature you're requesting.
这是有关您请求的功能的错误报告。
It's status is "reviewed" but I don't believe it's been implemented yet.
它的状态是“已”，但我认为它尚未实施。

Although Android can't find and connect to ad-hoc networks it sure can connect to Access Points. So as a work-around you can turn your Wireless Card into an Access Point using, for example, Connectify.
尽管 Android 无法找到并连接到 ad-hoc 网络，但它确实可以连接到接入点。因此，作为一种变通方法，您可以使用例如Connectify将您的无线卡变成接入点。

my friend and I are currently developing a java library implementing the AODV protocol (multihop routing suitable for mobile networks), in our bachelor thesis. The final 'product' includes a easy way to create/join an adhoc network on several android devices and an interface through the library, to send and receive messages. Unfortunately each type of phone such as hero, nexsus one... have a phonedepended way for createing a adhoc network so currently we are only supporting a few phones).
我和我的朋友目前正在我们的学士论文中开发一个实现 AODV 协议（适用于移动网络的多跳路由）的 Java 库。最终的“产品”包括一种在多个安卓设备上创建/加入临时网络的简单方法，以及一个通过库发送和接收消息的接口。不幸的是，每种类型的电话（例如 hero、nexsus one...）都有一种依赖于电话的方式来创建临时网络，因此目前我们只支持少数电话）。
this means that once this project is finished, people with rooted phones can implement their distributed applications (file sharing, games, ...) by simply including the library .jar file in their android projects.
这意味着一旦这个项目完成，拥有 root 手机的人可以通过简单地在他们的 android 项目中包含库 .jar 文件来实现他们的分布式应用程序（文件共享、游戏等）。
it's all open source by the way
顺便说一下，它都是开源的

you can connect your android device to a known ad-hoc network.
您可以将您的 android 设备连接到已知的 ad-hoc 网络。
edit /system/etc/wifi/tiwlan.ini
编辑 /system/etc/wifi/tiwlan.ini
WiFiAdhoc = 1
dot11DesiredSSID = <your_network_ssid>
dot11DesiredBSSType = 0
edit /data/misc/wifi/wpa_supplicant.conf
编辑/data/misc/wifi/wpa_supplicant.conf
ctrl_interface=tiwlan0
update_config=1
eapol_version=1
ap_scan=2
if that is too simplistic, see these instructions.
如果这太简单了，请参阅这些说明。

Support for peer to peer WiFi networking is available since API level 14.
自API 级别 14起就可以支持对等 WiFi 网络。

There are tonsof zeroconf-enabled machines out there, so this would enable discovery with more than just Android devices.
那里有大量启用 zeroconf 的机器，因此这将启用不仅仅是 Android 设备的发现。

Yes, but:
1. root your device (in case you've got Nexus S like me, see this)
2. install root explorer (search in market)
3. find appropriate wpa_supplcant file and replace (and backup) original as shown in this thread
是的，但是：
1. 根你的设备（如果你有像我一样的 Nexus S，请看这个）
2. 安装根资源管理器（在市场中搜索）
3. 找到合适的 wpa_supplcant 文件并替换（和备份）原始文件，如图所示这个线程
above was tested on my Nexus S I9023 android 2.3.6
