Abstract
Limitation of bandwidth, restriction of resources and frequent disconnection are main characteristics of ubiquitous computing environments. To reduce these kinds of problems, a new form of data delivery was proposed in which the server broadcasts data to mobile hosts that listen to the broadcast channel. In this paper, we propose a hybrid concurrency control scheme based on broadcast invalidation report. The scheme achieves high transaction throughput, because it uses of re-ordering and locking. By simulation experiments, we show that our scheme consistently demonstrates excellent performance with low space overhead in all parameter settings.
