| Summary |
Energy harvesting technology was introduced into wireless sensor
networks (WSNs) to solve the problem of the short lifetimes of sensor
nodes. The technology gives sensor nodes the ability to convert
environmental energy into
electricity. Sufficient electrical energy can lengthen the
lifetime and improve the quality of service of a WSN.
This paper proposes a novel use
of mutual information to evaluate data transmission behavior
in the energy harvesting WSNs.
Data at a sink for a node deteriorates over time until the next periodic
transmission from the node is received.
In this paper, we suggest an optimized intermittent
transmission method for WSNs that harvest energy. Our method overcomes
the problem of information deterioration without increasing energy cost.
We show that by using spatial correlation between
different sensor nodes, our proposed method can mitigate information
deterioration significantly at the sink. |
