Wireless Sensor Network (WSN); is a self-configured net-work of light-weight nodes, that are used in many applica-tions by sending their data through its network to a BaseStation (BS), which in turn delivers the data to its final desti-nation. In WSN, the sensor node’s energy is usually limited,and the overall power consumption of the network is a realchallenge. Many methods are used to overcome this chal-lenge by improving the overall power consumption and thusthe lifetime of the network. one of those methods is LowEnergy Adaptive Clustering Hierarchy (LEACH); that is arouting protocol based on clustering. For some applicationsWSNs are required to be dense to fulfill their tasks. However,in such dense networks, the burden over cluster head (CH)is increased. In this paper, an improved algorithm based onLEACH is proposed to maximize the lifetime of WSN, byusing another node to relieve CH’s burden. In this work, therouting path is modified by selecting a new node that hasthe highest residual energy in each cluster to be an alterna-tive gateway for the cluster head. After which, the routingpath will be decided based on distance. This modified algo-rithm outperforms the original LEACH by 4.35% increasein the residual energy, which prolongs the network lifetime.However, there is a slight increase in the overhead ratio.
