Clock Synchronization in Android Wi-Fi Direct Network

Abstract

Wi-Fi Direct Network is a new type of network and smart-phone devices may utilize this type of network to exchange information, such kind of network is widely replacing Bluetooth as the main communication method among smart-phones. Many new applications and games are developed based on this kind of network, in this thesis, the author explore the clock synchronization problem in Android Wi-Fi Direct network and design a prototype to synchronize the clock time of the Android devices. The prototype considers power overhead and deploys an efficient algorithm to balance the power consumption; meanwhile, the prototype considers multi-hop communication and allows the solution very high scalability.
