New Intention Repeater WiFi Broadcaster

habit of naming my headers hpp. I hate how windows names libraries. thats the Windows Socket Library. we neede that to interact with the operating systems socket modules.

What update would you recommend I make?

Minimize UDP Header Size and Avoid Unnecessary Protocol Options:

To minimize the UDP header size and avoid unnecessary protocol options, we'll use the IP_HDRINCL socket option. This option allows us to construct our own IP header, bypassing the default UDP header provided by the operating system. By doing this, we can send UDP packets with only the necessary information, reducing overhead.

Here's how you can set this option in your code:

cpp

Copy code


int enable = 1;

if (setsockopt(sock, IPPROTO_IP, IP_HDRINCL, (char *)&enable, sizeof(enable)) < 0) {

cerr << "Error setting IP_HDRINCL option" << endl;

// Handle error

}

Set Appropriate Socket Timeouts and Retries:

To set socket timeouts and retries, we'll use the setsockopt() function with the SO_RCVTIMEO and SO_SNDTIMEO options for both send and receive operations. These options allow us to specify the maximum time to wait for socket operations (e.g., send or receive) before timing out.

Here's how you can set socket timeouts for both send and receive operations:

cpp

Copy code


struct timeval timeout;

timeout.tv_sec = 5; // Set timeout to 5 seconds

timeout.tv_usec = 0; // Set microseconds to 0



if (setsockopt(sock, SOL_SOCKET, SO_RCVTIMEO, (char *)&timeout, sizeof(timeout)) < 0) {

cerr << "Error setting receive timeout" << endl;

// Handle error

}



if (setsockopt(sock, SOL_SOCKET, SO_SNDTIMEO, (char *)&timeout, sizeof(timeout)) < 0) {

cerr << "Error setting send timeout" << endl;

// Handle error

}

ZLIB Message Compression:

ZLIB is a widely used compression library that provides functions for data compression and decompression. You can use ZLIB to compress your intention message before sending it over the network, reducing the amount of data transmitted.

Here's how you can use ZLIB compression in your code:

cpp

Copy code


#include <zlib.h>



std::string compressMessage(const std::string &message) {

   z_stream zs;

   memset(&zs, 0, sizeof(zs));



   if (deflateInit(&zs, Z_DEFAULT_COMPRESSION) != Z_OK) {

       return ""; // Compression initialization failed

   }



   zs.next_in = (Bytef *)message.data();

   zs.avail_in = message.size();



   std::string compressed;

   char outbuffer[32768]; // Output buffer

   int ret;

   do {

       zs.next_out = reinterpret_cast<Bytef *>(outbuffer);

       zs.avail_out = sizeof(outbuffer);



       ret = deflate(&zs, Z_FINISH);



       if (compressed.size() < zs.total_out) {

           compressed.append(outbuffer, zs.total_out - compressed.size());

       }

   } while (ret == Z_OK);



   deflateEnd(&zs);



   if (ret != Z_STREAM_END) {

       return ""; // Compression failed

   }



   return compressed;

}

These optimizations should help you minimize UDP header size, avoid unnecessary protocol options, set appropriate socket timeouts and retries, and implement ZLIB message compression in your code. Make sure to integrate these optimizations into your existing codebase as needed.















should explore some of these options as well. chat gpt suggested ZLIB message compression. If we could COMPRESS the multiplid hashed value into a smaller size we could transmit even more.

Heres my code i never attempted using raw sockets or a custom header yet. But i implemented ZLIB compression as an option. ITS like putting our hashed value into a 7zip basically. I havent multipled the zlib compression but it should be faster since it doesnt take up as much space its probably even within the MTU.

EDIT UPDATED IT AFTER FIXING IT. Now i GET CONSISTENT 2+ megabyte transfer per second. And no more errors. And i no longer have to restart my router after using it. IT AMAZING. i have no idea if ZLIB compression helps. But either way i am sending consistent megabyte transfers broadcasting every second. no errors about sockets or anything like that NO BROADCAST WAITING OR ANYTHING. its awesome. no idea of the effects but when i sleep tonight ima have it on.

Im pretty sure its this_thread::sleep_for(milliseconds(10)); inside the loop. Since the bottle neck is the packet transmission perhaps the 10 milliseconds minimum between loops stops the crash or overflowing. perhaps experiment with higher inervals of sleep.
Its crashing cuase its using 100 percent of hte CPU and making your laptop overheat or malfunction. i actually get better packet transmission consistent 10 mb per second with 10 ms sleep for intervals.
I think it crashes because it uses the entire CPU and might be heating up to oa large extent. perhaps with 10 ms interval sleep minimum it wont od that.
