How to remotely control your imac with your macbook from

Recently, a few Mac users have complained that their MacBooks/Pros/Airs keep waking up from sleep. As a result, when they go to use them again, maybe the next morning, their batteries are partly discharged – more than they could have been if they had stayed asleep.
In this sadly archived post, Apple discusses the Wake on Demand system, which allows connecting clients to wake a sleeping Mac that is sharing with them. Open the Energy Saver pane and uncheck the item Wake for network access, in addition to making sure your Mac isn’t offering a sharing service that might wake it up.
The most popular issues these days are alerts, which seem to come from everybody and their dog, and many of which do not seem to be completely under your control. The better apps are listed in the Alerts pane, but there is no option to disable or mute them during sleep when viewing their settings.
If your Mac is waking up when it should be sleeping, the only way to figure out what’s going on is to search at your log files and use Consolation 3 to find the incident that caused it to wake up. It can be aggravating if you don’t know why anything happened.

Switch your attention to Screens and try to link to the Mac. If the Mac does not wake up after this link attempt and Put hard disks to sleep when possible was allowed, go back and disable this function, then try connecting again.
If you connect to a MacBook, MacBook Air, MacBook Pro, or any other Apple laptop, it must be plugged into a power source (power socket, external monitor with power, etc.) to wake up.
“When you turn on FileVault, other security features are also switched on to ensure security. When you turn on FileVault, for example, you’ll need a password to log in when your Mac is sleeping or after you’ve turned off the screen saver.”

I’ve read that sending the magic packet would wake it up, but what I really want is to be able to connect to the Mini over the network and make it wake up on demand without having to send a magic packet.
There is no way to wake up the machine without sending a magic packet. If that were possible, each packet would jolt it awake. And you’d be shocked how many packets will arrive at any open port.
Wake on Demand operates in combination with Bonjour Sleep Proxy, a service that runs on your AirPort Base Station or Time Capsule. When you allow Wake on Demand, any Mac running Snow Leopard on your network will automatically register itself and its shared objects with the Bonjour Sleep Proxy. When a Mac running Snow Leopard receives a request to access a shared object, the Bonjour Sleep Proxy asks the Mac to wake up and handle the request. If that request has been completed, the Mac will return to sleep at the time set in the Computer Sleep section of the Energy Saver preferences window.

For remote access, I have a stack of Apple Mac minis running SSH servers. The issue is that I can’t seem to rouse them from their slumber. According to what I’ve learned, starting with Mac OSX 10.7, you’ll need to set a boot time choice – darkwake=0 10.7 and darkwake=no 10.8. So I gave it a shot and realized that it would probably work for a wired link, but I’m using WiFi.
I know I could simply set the stack of Mac minis to not sleep, but I’m looking for a sleep-enabled alternative. These services don’t need a fast initial response because they’ll be active as soon as the link is established, and once they’re no longer active, they’ll hopefully go back to sleep.
I’m using avahi-daemon on a FreeBSD box to try and wake the Macs using the Bonjour Service, but it doesn’t seem to work. I tried registering the service as Gordon suggested in the comment below, but that only prevents timeouts when finding and resolving services. When it’s asleep, it still doesn’t allow ssh connections to port 22.
