A distributed type of network in which there are large numbers of sensor nodes deployed such that the surroundings of the area can be monitored and important information can be gathered is known as wireless sensor network. The sensor nodes present within the network are very small in size and have very less power for processing the tasks. The power consumption is minimized by applying the energy efficient clustering algorithm known as LEACH. There are several clusters of sensors in which LEACH is partitioned the localized coordination and control is utilized for constructing this approach. In this research work, the cache nodes are deployed in the network for the data aggregation from the wireless sensor nodes. The proposed algorithm is implemented in MATLAB and results are analyzed in terms of certain parameters. It is analyzed that in the proposed algorithm number of dead nodes are less, alive nodes are more and number of packets transmitted to base station are also high as compared to existing algorithm.
