Using Group Communication to Support Mobile Augmented Reality Applications

Augmented reality and group communication in wireless ad-hoc networks form relatively new fields of research. When using group communication ordering and timeliness requirements are important. Moreover, when using wireless ad-hoc networks, the possibility of network partition is a serious consideration. In this paper we explore these three issues in the context of using group communication to support mobile augmented reality applications. We describe a policy that enables us to handle partitions and failures, while allowing the members in a partition to make progress, although limited by the application’s consistency requirements. We introduce an approach to determining the message ordering requirements needed to maintain a desired level of consistency and timeliness requirements that should be met in order to have the application state correspond to the sequence of events perceived in the real world.
