To solve such a problem, replica distribution methods which distribute replicas of data items to other mobile hosts and maintain them have been proposed. In this paper, we propose and evaluate a method to enhance the accessibility to data items that are associated with locations and requested by Geocast from hosts. This method is based on flooding of replicas of data items, and it uses the locations of mobile hosts and the associated locations of data items for controlling the range of the replications and the redundancy of the replicas. Furthermore, to keep the accessibility to such data high, replicas are dynamically relocated after the movement of hosts. We confirmed the effectiveness of the proposed method by detailed simulations including multiple data request models. Simulation results showed that the proposed method achieves high accessibility to location-dependent data especially when the storage size is small. © 2007 Wiley Periodicals, Inc.

无线自组织网络上与位置相关的数据的副本分布
在移动自组织网络中,由于主机移动引起的拓扑变化和无线链路状态的变化,使得移动主机难以保持对其他主机数据的可访问性。为了解决这一问题,提出了副本分发方法,将数据项的副本分发到其他移动主机并对其进行维护。在本文中,我们提出并评估了一种方法,以增强对与位置相关的数据项的可访问性,并由Geocast从主机请求。该方法基于数据项副本的泛滥,并使用移动主机的位置和数据项的关联位置来控制副本的范围和副本的冗余。此外,为了保持对这些数据的高可访问性,在主机移动后,副本会动态重新定位。通过包含多个数据请求模型的详细仿真,验证了所提方法的有效性。仿真结果表明,该方法对位置相关数据具有较高的可访问性,特别是在存储空间较小的情况下。©2007 Wiley期刊公司电子工程学报,2009,29 (3):397 - 397;在线发表于Wiley InterScience (www.interscience.wiley.com)。DOI 10.1002 / ecja.20320
