New Protocols Show p to 76 Percent Speed Jolt For Iphones, Ipads
The novel employment of accelerometers, global positioning system locators, gyroscopes, and compasses that are standard features of smartphones and tablets can speed up wireless networks by as much as 76 percent, according to research from the Massachusetts Institute of Technology.
The researchers say that deploying appropriate rate-adaptation protocols on mobile devices can boost performance by overcoming some of the innate network problems of mobile devices. Clues supplied by the built-in sensors can enhance the performance of wireless network protocols, which account for whether the device is still, how fast it is moving, and the direction it is heading in with the goal of performance optimization. The research suggests two performance improvement methods: the maximization of the bit rate at which protocols transmit data and the minimization of the number of handoffs between Wi-Fi access points to better accommodate real-time applications by reducing delay and jitter.
The sensor data interpretation software has so far been developed for Linux and Android devices, but the researchers say it should be simple to embed it within other mobile platforms.
