Abstract
By analyzing characteristic and application of wireless sensor networks( WSNs)
propose a new kinds of data storage meachanism for WSNs based on cooperation region
in order to improve data reliability under the premise of node energy-saving and memory overhead. Point out design object and system architecture
define mechanism for providing in-network storage service in sensor environments
and define data storing cooperation region
manager node and its establishment mechanism algorithm and flow for data storage and extraction are given based on network coding theory in cooperation region. Simulation results show that the mechanism is capable to improve information
reliability with low energy overhead.
