Data Management Framework for Wireless Sensor Network Using Agent and Policy Technology
Jie Li · Computer Technology and Development · 2008
Data management plays an important role in wireless sensor networks(WSNs).In order to make users manage the data efficiently and further reduce data stream,overviewed the actuality of data management,and proposed data management architecture for WSNs based on hierarchical framework,which combines agent with policy technologies.There is a policy warehouse in the sink node and in each node too.Sink node sends a mobile agent(MA) which takes the policy to cluster head,the cluster head puts it into policy warehouse.Then cluster head send the policy to common nodes.In each node,there is a policy agent who used to execute policies and renovate policy warehouse.By the data management architecture,the whole network's life time will be further prolonged.
