摘要
在移动自组网中,网络频繁的断接使得数据的可访问性低于传统的固定网络中的数据可访问性。当网络中存在一个数据项的多个副本时,应避免对某一个数据项的所有访问都集中在某一台移动主机上,从而防止主机电源耗尽而脱离整个网络,降低数据的可访问性。本文基于对移动主机的电源能力的考虑,提出了一种新的数据项或副本位置管理的方法,有效的避免因为电源耗尽而导致的网络分裂,从而保证了数据的可访问性。
In ad hoc networks, disconnections occur frequently, which causes frequent network division. Therefore, data accessibility in ad hoc networks is lower than that in the conventional fixed networks. When there have multi-replicas of a data item in ad hoc networks, we must avoid that all accesses of the data item processed on one mobile host to prevent the mobile host break away from the network by power exhaustion and lower the data accessibility. In this paper, we propose a method to manage locations of data items or replicas which avoids network partition because of power exhaustion, and consequently guarantees the data accessibility.
