Tóm tắt

One of the features of wireless ad hoc network technology is that networks can be constructed without a fixed network infrastructure. Communication in a disaster is one application of a mobile ad hoc network. Data on the disaster can be collected by mobile hosts. The mobile hosts can then exchange data to decide rescue priority, etc. However connectivity in a wireless ad hoc network is not guaranteed because hosts encounter obstacles. Thus, the accessibility of the data objects held in a particular host is very important. To ensure accessibility, we propose a method for distributing replicas of regional data on mobile ad-hoc networks.
