Abstract:
This paper presents the introduction of
network coding technique into the data
gathering process of cluster-based wireless
sensor networks (WSNs), which possess the
limited energy and computing resources. The
network coding can indirectly reduce the amount
of energy consumed for the transmissions from
the cluster heads to the base station. An energyefficient
2-hop path selection protocol is also
applied to further reduce the energy
consumption for data transmission from sensor
nodes to a cluster head node. We set up a
computer simulation in MATLAB to see the
performance of our proposed scheme. Energy
consumption and the number of transmissions
are used as the performance evaluation metrics.
The numerical results show that our proposed
scheme can reduce the energy consumption for
data transmissions from sensor nodes to the sink
and improves the lifetime of the sensor network.
