Abstract: In this study, we propose an algorithm considering node movement and considering the variable number. LEACH is an energy efficient protocol but has a disadvantage in that the success rate of data transmission is low because it does not consider the mobility of nodes. LEACH-Mobile is the protocol that improved this. Since, LEACH-Mobile retransmits data that failed to transmit, it has a disadvantage that it consumes more energy than LEACH and does not consider the situation where the number of nodes is variable. The cluster head is selected based on the residual energy of the node in consideration of the situation where the number of nodes is variable. In this study, we compare LEACH-Mobile with the proposed algorithm by simulating the environment in which the number of nodes changes in each round and nodes move every round.
