Abstract
Methods, devices, and computer program products for synchronization of wireless devices in an ad-hoc network are described herein. In one aspect, a method for synchronizing a wireless communication apparatus is provided. The method includes generating, at a wireless communication apparatus, one or more messages identifying a second device to generate prospective synchronization messages. In some aspects, the second device is a back-up root device. The method further includes transmitting a synchronization message. In one aspect, a root device for an ad-hoc network is responsible for generating synchronization messages for nodes of the ad-hoc network. The root device also generates and transmits a message which identifies a back-up root device. The back-up root device may assume responsibility for generating synchronization messages for the ad-hoc network in the event that the wireless communication apparatus no longer generates synchronization messages for the ad-hoc network. In an embodiment, the generated message identifying the back-up root device is included in a synchronization message.
