Description: In wireless sensor networks, the power resource of
each sensor node is limited. Minimizing energy dissipation and
maximizing network lifetime are important issues in the design
of routing protocols for sensor networks. In this paper, Cluster
routing protocol LEACH (Low-Energy Adaptive Clustering
Hierarchy) is research and improved. We extend LEACH
stochastic cluster-head selection algorithm via changing the
round time According to the situation of sensor network. It is
named Variable-round LEACH. The result simulated in NS2
shows that the energy is significantly reduced and the lifetime
of the whole network is increased compared with the previous
routing algorithm for the sensor networks. Platform: |
