The prolongation of a wireless sensor network lifetime is closely related to the energy consumption of the most energy-consuming node of the network. As shown here, the energy consumption of a network is closely related to the nodes' traffic load. In this sense, for minimizing the energy consumption of the most energy-consuming node and prolong the network's lifetime, a traffic load-based algorithm is proposed here. The proposed algorithm, by exploiting the results of a simple shortest path approach, discovers, for every node, the neighbors that hold the same distance (in hops) from the sink node, with the initially assigned parent. If such neighbors are found then all of them are used as parents and the traffic load is forwarded to all of them interchangeably. The proposed algorithm is also evaluated under simulation results, showing that it achieves the goals set and that it prolongs the network lifetime.
