如何计算使用wifi的Android手机的功耗？
我在 Android 1.6 手机上实现了一个路由协议，该协议使用无线（自组织）网络来交换消息。现在我想从能耗的角度来评估它，基础是尝试计算传输单个数据包所浪费的能量，有人知道如何做到这一点吗？欢迎提供软件/硬件解决方案！
I have implemented a routing protocol on an Android 1.6 mobile that uses wireless (ad-hoc) network in order to exchange messages. Now I would like to evaluate it under an energy consumption point of view, the base would be to try to calculate the energy wasted to transmit a single packet, do anybody has any idea how to do that? Software/hardware solutions are welcome!

我不相信任何应用程序都会给您带来任何形式的有意义的结果。您确实需要寻找硬件解决方案，并且它可能需要自制。
我用于手机功率测量的设置包括以下内容：
当您设计系统时，请记住，6 或 9 伏电源的小值电阻器上的压降将非常小，因此您的 ADC 需要非常灵敏，才能获得有意义的结果。
一旦掌握了所有这些，您将能够随着时间的推移观察设备电流。您会发现这种差异远远超出您的预期。手机会一直打开和关闭各种电路。特别是，当访问蜂窝网络时，您会看到相当大的功率峰值。
经过一番调查后，您将能够看到 WiFi 何时启动，尤其是传输突发。
祝你好运。
I don't believe that any application will give you any form of meaningful result. You really need to be looking at a hardware solution, and it will likely need to be home-brew.
The set-up I have used for power measurement on mobiles consists of the following:
When you are designing the system, remember that the voltage drop across a small value resistor for a 6 or 9 volt supply will be very small, so your ADC needs to be pretty sensitive for you to get meaningful results.
Once you have all of this, you'll be able to observe device current over time. You will find that this varies far more than you may expect. The phone will be turning on and off all sorts of circuitry all of the time. In particular, you will see fairly large power peaks when the cellular network is being accessed.
After a bit of investigation, you'll be able to see when the WiFi is powered up, and the transmit bursts in particular.
Good luck.
我相信有许多应用程序可以跟踪应用程序的功耗。您可以使用其中之一来在激烈的测试期间观察您的应用程序。
编辑：可以尝试的一个应用程序是power coach。请注意，正如它所说，功耗可能会根据实际硬件的不同而有很大差异。您可能想在几个不同的平台上进行测试以查看差异。
I believe that there are a number of apps available that will track the power consumption of an application. You could use one of those to observe your application during an intense test.
Edit: One app to try would be power tutor. Note that as it says though, power consumption is likely to vary a lot depending on the actual hardware. You might want to test it out on a few different platforms to see the differences.
是的，PowerTutor 是密歇根大学博士论文成果中最可靠的应用程序之一。 PowerTutor 为您提供 Android 上所有正在运行的应用程序的能耗。然而，该应用程序在 HTC G1、HTC G2 和 Nexus one 上运行得更加准确，因为它是为此类产品开发的。
Yes, PowerTutor is one of the most reliable application produced in result of a PhD thesis in University of Michigan. PowerTutor gives you energy consumption of a all running application on Android. However, this application is working more accurate on HTC G1, HTC G2 and Nexus one since it is developed for such products.
