The dispersion of the wireless sensor networks( WSNs) node deployment
as well as own resources limitation of node require the WSNs routing algorithm must meet design principles of low cost and low power consumption. Various WSNs routing algorithms including Cluster-Tree
AODV
LEACH and RPL
are compared and analyzed. Using transmission distance between nodes and residual energy of node as unit of measurement
RPL algorithm is improved by using energy balance strategy. In cooja simulation environment
the network with different number of nodes is constructed
and the improved routing algorithm is used for simulation and test
which proves that this routing algorithm can prolong the life cycle of the network.
