| Abstract |
This paper proposes an algorithm that improves the problems of the DL-LEACH protocol, which is an improvement of the LEACH protocol, a representative protocol of wireless sensor networks. The DL-LEACH can generate a absence of the cluster head at any layer in any round due to the limitations of the stochastic threshold equation used when electing cluster heads. The absence of a cluster head cannot form a cluster, and cannot transmit data of detected nodes to a base station. This means that the transmission success rate of DL-LEACH is not constant for each round. In order to solve this problem, first, the number of cluster heads of the sensor field is equally selected for each round, and the number of cluster heads of the selected sensor field is distributed according to the node ratio of each layer to improve the absence of the cluster head. To verify the effectiveness of the proposed algorithm, we simulated using MATLAB. We also compared the transmission success rates between DL-LEACH and the improved DHL(Dual Hop Layered)-LEACH protocol. |
