## 2 Basic Background and Motivation
The area-based line structures are simple to create, are accessible to source and the sink nodes can reduce the hotspot issues, although flooding through them increases the energy usage. The goal is accomplished using the mobile wireless sensor network's design [20]. The directional routing scheme discussed in [21] involves the strategies to develop the path selection criteria between the source and destination. Similarly, various energy efficient schemes for the dynamic wireless sensor network as provided in [22] and gives an idea on the different strategies to develop such a network. Rendezvous routing discussed by [PERSON] et al. [23], has recently been the focus of numerous studies aimed at reducing the utilized energy and prolonging the lifespan of the sensor networks. Based on the virtual ring formation discussed in [24], ring routing is a rendezvous routing mechanism. While using geographic routing to forward the packets in the route of the base station, the sink makes its position accessible to the ring. As a result, the ring nodes always preserve the sink's most recent position. By using a similar technique, the source nodes ask the ring for the most recent sink location information. While preserving the enclosed and encapsulated information from the network center features, each ring node freely chooses new ring nodes among its neighbors when its batteries are almost empty. Even if the ring structure can be accessed easily, the proposed mitigation approach results in a low overhead, it becomes challenging to conserve energy and regulate the overhead in large or sparse networks. Thus, the multipath-based multicast routing concept is introduced in [25]. In our work, we concentrated on the idea of the construction of ring routing with a multicast mechanism that aids in the resolution of these issues. Most of the state of art techniques ignore the delay and the related packet loss brought on by the sink mobility, due to the frequent sink position advertisement, which increases the energy consumption and decreases the network's lifespan. As cited in [26] the authors have proposed an energy and delay efficient data acquisition technique by selecting optimal visiting points. However, the selection of the grid points is time consuming. This motivated us to develop the proposed work for resolving the objective of optimizing the determination of the nodes for the sink advertisement, thereby optimizing the energy utilization by managing the control overhead in a mobile sink. Thus, the lesser sink position advertisement, due to the sink mobility throughout the network provides faster data delivery. The major contributions of our paper are as follows. * The network deployment of the hierarchical-based heterogeneous wireless network with the mobile sink;
* The cluster head selection, based on the residual energy assuming at least one per group with a higher energy density than the normal node;
* The selection of the ring node by obtaining the one-hop neighbor enclosing the sink node which contains the maximum residual energy to store and forward the sink node link advertisement to the cluster head;
* The modified ring implementation, based on the multicast and multipath approach with the performance evaluation, such as the control overhead, energy utility, throughput and delay metrics.
