Study of ZiFi- A Zigbee Application
نویسندگان
چکیده
WiFi networks have enjoyed an amazing penetration rate in recent years. However, due to the limited coverage, existing WiFi infrastructure only provides interrupted connectivity for mobile users. Once leaving the current network coverage, WiFi clients must actively discover new WiFi access points (APs), which wastes the precious energy of mobile devices. Although several solutions have been proposed to address this issue, they either require significant modifications
