The main goal is to reduce node energy consumption and prolong the network life time.An improved algorithm based on LEACH is proposed which uses another cluster head to transmit data and can balance the energy loss within the network.It shows that it can extend the life time in the simulation experiments on NS2 compared with the former algorithm.

| Routing algorithm is one of the key technologies of the wireless sensor network. The main objective is to reduce node energy consumption and extend the network life time. In this regard, LEACH is a low-energy adaptive hierarchical routing algorithm. In this paper, an improved algorithm is proposed based on LEACH, which selects another cluster head to tansmit data to the base station. As a result, it can balance the energy loss within the network. In the simulation experiments on NS2 we show that it can extend the network life cycle compared with LEACH. |
