Abstract: This study proposes inner cluster multi-hop transmission to improve the energy consumption efficiency of the LEACH protocol. Since the LEACH protocol randomly selects cluster heads by threshold stochastic and forms any clusters, there may be a member node whose transmission distance is longer than the distance threshold value. If the transmission distance of any member node is longer than the distance threshold value, this member node quickly consumes energy. Therefore, we considered inner-cluster multi-hop transmission to reduce the transmission distance of these member nodes. And this study has derived the minimum threshold distance for efficient multi-hop transmission. In addition, we have let the member node determine the Hop number according to the minimum threshold distance. As a result, when the inner cluster multi-hop transmission is applied to the LEACH protocol, the energy efficiency is improved as the density of the node becomes smaller.
