Abstract: This paper proposes an improved AODVjr routing algorithm because of the
insufficiency energy equilibrium of existing AODVjr algorithm, combined with the characteristics
of the Clust-tree algorithm and the node energy analysis. Improved algorithm using the neighbor
table to find the destination node before start the routing discovery process, avoiding the use of
low energy node as far as possible and add flag flags to control the RREQ packet transmission
range in routing discovery process to reduce work's overall energy
simulation results show that the algorithm can effectively reduce work energy consumption
and reasonable work load, reduce the number of death, prolong work life cycle.
