A Wireless Sensor Network (WSN) is a collection of large number of tiny sensor nodes deployed in a field to survey the surroundings phenomena. Since, energy consumption is the crucial challenge in those networks, exploiting judiciously the energy reserve of nodes is the key for designing protocols. Distributing the energy dissipated throughout the wireless sensor network in one of used techniques to maximize the service time duration of the WSN. In this paper, the authors present a hierarchical cluster-based routings protocol for Wireless Sensor Network. The proposed method allows a best distribution of energy load over the whole network nodes, which permits to extend the network lifetime.
