The way to organize WSNs can be divided into three categories: (a) the cluster routing methods; (b) the hierarchical routing
method; and (c) the itinerary routing method [14,15].
We evaluated TCBSP using MATLAB, where nodes are employed in the form of tree cluster based structure by hierarchical routing
protocol TEEN with decision tree  and Dijkstra's shortest path algorithm.
The topics include interval-valued hesitant fuzzy geometric Bonferroni mean aggregation operator, deep learning with large scale dataset for credit card data analysis, improving the histogram for infrequent color-based illustration image classification, an improved intelligent student advising system, and a quality-of-service-aware hierarchical routing
protocol based on signal-to-interference plus noise ratio and link duration for mobile ad hoc networks.
They argued that, the comprehensive study of this set of protocols can be helpful for designers of MWSNs in selecting appropriate hierarchical routing
protocols for a specific application.
ZHLS (Zone-Based Hierarchical Link-State Routing) [1, 12] protocol incorporates location information into a novel peer-to-peer hierarchical routing
Objective: CHARISMA proposes an intelligent hierarchical routing
and paravirtualised architecture that unites two important concepts: devolved offload with shortest path nearest to end-users and an end-to-end security service chain via virtualized open access physical layer security (PLS).
techniques divide the network into distinguished clusters.
Most of the existing secure hierarchical routing
protocols focus only on the cryptographic solutions to achieve routing security goal.
Their topics include enhancing electronic learning systems and methodologies with advancements in distributed computing technologies, a security framework for networked radio frequency identification, a walk through programming models for sensor networks, a survey of wireless sensor network security attacks, a comparative analysis of hierarchical routing
protocols in wireless sensor networks, and a low-loss energy-aware routing protocol for data gathering applications in wireless sensors.
A sampling of topics: new hierarchical routing
protocol for WSNs, novel VNS algorithms on asymmetric traveling salesman problems, electric load forecasting, real-time visual feedback enhances Tower of Hanoi manipulation task, and part-of-speech approach to evaluation of textbook reviews, among many others.
It is the most popular hierarchical routing
algorithm for sensor networks.
