Accessing information through wireless devices is becoming more and more popular. When the size of the accessed information is large, a great amount of access latency is incurred while a mobile user (MU) migrates across cells. This paper investigates this problem and proposes an effective way of delivering such data to the MU in ubiquitous computing systems. A cell-encoding scheme is proposed for the support of this efficient data delivery. The method is carefully evaluated on its feasibility and efficiency.
