Abstract: Wireless sensor network is a wirelessly configured network of sensor nodes with limited power such as batteries. If the sensor node's battery is exhausted, the node is no longer available. Therefore, if the network is to be used for a long time, energy consumption should be minimized. There are many wireless sensor network protocols. To improve energy efficiency, including cluster-based and chain-based protocols. Cluster-based protocols elect cluster heads and divide sensor field into clusters. The cluster head collects the data in the cluster and transmits it to the base station. In the case of nodes elected as cluster heads, there is a problem of energy consumption. The chain-based protocol links sensor nodes in a chain and finally transmits all data to the base station. In this study, we intend to increase the network lifetime by using a chain to reduce the energy consumption of the cluster head in the cluster-based protocol, LEACH protocol.
