Abstract

Lack of synchronization mechanism in IEEE 802.15.4 standard for cluster-tree topology has restricted its use to non-beacon mode. Initial works in this direction are more centralized in nature whereas more recent works follow the distributed way. The former way of achieving synchronization have performance limitations in terms of scalability and overhead. In this paper, we propose a distributed beacon synchronization scheme that requires lesser transmissions and results in improved channel utilization. Apart from that, the proposed scheme also minimizes the number of collisions during beacon transmissions thus lowering the number of orphan nodes. Analytical and simulation studies corroborate our findings.
