Q-Leach protocol using intermediate gateway nodes for WSN

Networks that do not include use of any wires or any physical links are referred to as wireless networks. Node deployment is done in the network that is known as sensor nodes, the responsibility or the task of these nodes is to enable communication in the network. These nodes have some energy value on which the performance of network depends like more the residual energy of nodes, more the network lifetime. The network performance also depends on the round for which first dead node is obtained and the round for which last alive node is achieved. Much advancement has been done in the field of energy efficient protocols to improve the energy efficiency of network. Clustering process was introduced and then techniques for Cluster head selection were developed and still more to come. Two most considered factors for designing energy efficient protocols are distance between the nodes and the energy value of nodes. The conventional protocols like LEACH, HEED, DEEC and QLEACH are designed for improving the energy efficiency in WSNs. The effort in the paper is proposing one such protocol for improving energy efficiency and lifetime of WSNs and this protocol is an enhanced form of QLEACH protocol. The gateway node is introduced in proposed technique for reducing the energy consumption& the distance of nodes. The results are demonstrated and proved using MATLAB. The result section represents the proficiency of the implemented work by demonstrating it using comparison graphs.
