The data packets that are produced by these networks can be continuous, event-based, or query-driven, and they have a characteristic that is application-specific in character. To avoid wasting any energy, these packets must be transferred to the base station in an effective way. Making ensuring that data packet transport is reliable and energy-efficient is one of the most crucial considerations to make when attempting to enhance the performance of a wireless sensor network (WSN). The conventional method of retransmissions drains the battery of the node and adds to the amount of communication overhead, both of which contribute to network congestion, which in turn hinders the network's ability to transmit data packets reliably. Congestion results in the depletion of the node's energy supply, a decline in the performance of the network, and an increase in network latency as well as packet loss. Clustering is one of the most effective methods for gathering information from several sensor nodes in a time- efficient manner. In this work, we propose an efficient data delivery technique that can help to maximize the network throughput rate without affecting the network performance. In this study, a stable CH selection & link cost function (LCF) based data aggregation approach is developed to increase the throughput & lifetime of a wireless sensor network, CH stability, and energy-efficient data aggregation. The multi-objective parameters such as energy and distance to base station are involved to improve CH stability which improves the data aggregation. Following the selection of the CH, a link cost function (LCF) that is based on relay selection and data aggregation is used in order to find the optimal path between the cluster head and the member nodes for the transmission of data in an efficient manner that uses the least amount of energy. In order to make the most of this time-saving method, the data are consolidated at CHs. Keywords: WSN, Clustering, Cluster head Selection, Energy efficiency, Data aggregation, Maximize Throughput. I. INTRODUCTION A significant number of energy-constrained sensor nodes are often included in wireless sensor networks or WSNs. WSNs are placed in a region at random in order to collect data on a variety of environmental characteristics and then send that data to a base station (BS) for use in monitoring and detecting applications [1]. In recent years [2,3], Because of their ubiquitous use in several industries, including military use, surveillance, human health detection, and others, they have attracted the attention of academics. It is extremely challenging to either recharge or replace the batteries of SNs used in WSNs because these networks are typically placed in high-risk areas. In addition, human operation of the network is quite challenging, which presents certain difficulties in regards to the deployment of WSNs [4–6]. Researchers should prioritize the efficient exploitation of the battery power available in SNs when creating protocols and hardware architectures as a means of mitigating the negative consequences of the restrictions described above [7]. This can be accomplished by maximizing the use of the battery power. In order to make the sensor network more energy-efficient as a consequence, many routing techniques have been proposed [8,9].
