By relying on the application, a wireless sensor network could be heterogeneous in nature, which means the sensor nodes either static or mobile based on the requirements of an application. The energy-hole problem may cause by the static deployment of source nodes and sink due to the nodes should always be active in the sink’s one-hop neighbour for data transmission from the source nodes. The coverage holes is resulted and network performance is reduced. For efficient data aggregation and QoS maintenance, one of the optimal methods is used as the clustering. More energy is consumed by the Cluster Heads (CH) that located near BS in cluster-based WSNs and their energy exhausts with rapid speeds than the other ones. Thus, the premature death of nodes and frequent rotation of CH have resulted. The Enhanced Particle Swarm Optimization and a multi-objective CH selection have introduced for relay selection with mobile sinks (MOCH-EPSOR) for improving the sensor network lifetime and CH stability for energy-efficient data aggregation. A single mobile sink deployment in larger networks is lead to different problems in large networks such as end-to-end delay in data collection, coverage, and node failure or link failure, etc. In this paper, multiple mobile sinks have introduced. Different multi-objective parameters like link quality, residual energy, communication cost, and node proximity are also considered for improving the stability of CH that enhances the data aggregation. For detecting the optimized route between member nodes and cluster head, an enhanced Particle Swarm Optimization (PSO) algorithm is incorporated with a modified fitness function for energy-efficient data transmission. For aggregation from the respective CHs, the MS’s are moving along the clusters and retain in each cluster for certain time period after data aggregation at CHs. The experimental results proves that the proposed MOCH-EPSOR scheme improves the network lifetime and QoS than the previously proposed energy efficient protocols.
