A double chain transmission routing algorithm based on Ant Algorithm (ADCT) is proposed. Firstly

it uses the double selected cluster method to choose cluster heads

which takes many factors such as residual energy of nodes

average energy of network and the size of the cluster into consideration. Secondly

it uses Two-way transmission way based on optimized ant algorithm to communicate cluster heads with the sink-node. The simulation results show that the proposed algorithm significantly improves the network performance

prolongs the network lifetime and balances the network energy consumption.
