Abstract: In order to extend the node load the service life of the AD hoc network overload environment, need to overload of AD hoc network node load energy equalization algorithm is studied.Using the current algorithms, existing network node energy consumption imbalance caused the problem of premature network paralysis.For this, put forward a kind of based on hierarchical structure under the node load overload of AD hoc network energy equalization algorithm.The algorithm in the form of distribution of local information to measure the energy of the AD hoc network indicators, the energies of the AD hoc network is divided into three levels to normal, warning, danger and on the basis of the residual energy of nodes in different grades, different methods for AD hoc network nodes data transmission, finally USES the hierarchical algorithm balanced AD-hoc network energy.Simulation experiment proves that the proposed algorithm effectively extend the service life of AD hoc network.
