Abstract
With combination of sleep scheduling mechanism and network coding
a strategy for lowpower consumption data retransmission is proposed which is suitable for wireless senor networks(WSNs)with stable sleep probability.According to dormant status of nodes at different times
lost data packets of awake nodes can be retransmitted by network coding.At the same time
theoretical analysis and simulation can verify that the method can reduce times of transmission of data packets effectively on basis of assurance of correctness of retransmission
and life time of network can be prolonged.
