Researchers at the Massachusetts Institute of Technology have discovered that making use of the sensors found inside cell phones — GPS radios, accelerometers and gyroscopes — can dramatically improve hand-offs between access points and increase wireless data speeds. The researchers developed a handful of protocols that can be used to infer the trajectory of a smartphone and select the best access point based on the direction of travel and how long the phone is likely to have access to that particular access point. The researchers also determined that using the protocol can help phones more accurately control bit rates as they moe through access point coverage, which leads to a dramatic increase in throughput (average of 50% speed increase). The researchers have a number of protocols that they believe will benefit users of mobile devices and wireless network.
