Homogeneous and Heterogeneous Clustered Sensor Networks

Dear Colleagues,

Nowadays, wireless sensor networks (WSNs) are receiving considerable attention due to their various applications. Clustered SNWs in particular can operate in homogeneous as well as heterogeneous network topologies. They provide many advantages, including scalability and a reduction in data transmission to the base station. Moreover, they can be formed as single-hop or multi-hop WSNs.

In recent years, routing and data congregation approaches have been addressed by many researchers. Moreover, sensor nodes are typically power-limited; therefore, energy efficiency is a central research area. In addition, the complexity of hardware design is an important aspect for WSNs. While heterogeneous networks may achieve a reduced hardware cost and complexity, homogeneous networks can offer a balanced energy distribution among nodes. Therefore, tradeoffs and comparative studies for various clustering and protocols in single-hop and multi-hop homogenous and heterogeneous WSNs require contributions from research community.

This Special Issue aims to provide the readers of Sensors with recent technical contributions on the design aspects of WSNs, their complexity analysis, and performance tradeoffs. The main topics of interest include, but are not limited to, the following:

1. Routing in clustered WSNs.
2. Clustering mechanisms and protocols.
3. Optimization of cluster head selection.
4. Optimization of number clusters.
5. Single- and multi-hop clustered WSNs.
6. Cost analysis.
7. Performance metrics.
8. Performance–complexity tradeoffs.
9. Energy efficiency–complexity tradeoffs.
10. Optimization algorithms.

Manuscripts can be submitted until the deadline. All submissions that pass pre-check are peer-reviewed. Accepted papers will be published continuously in the journal (as soon as accepted) and will be listed together on the special issue website. Research articles, review articles as well as short communications are invited. For planned papers, a title and short abstract (about 100 words) can be sent to the Editorial Office for announcement on this website.

Submitted manuscripts should not have been published previously, nor be under consideration for publication elsewhere (except conference proceedings papers). All manuscripts are thoroughly refereed through a single-blind peer-review process. A guide for authors and other relevant information for submission of manuscripts is available on the Instructions for Authors page. Sensors is an international peer-reviewed open access semimonthly journal published by MDPI.

Please visit the Instructions for Authors page before submitting a manuscript. The Article Processing Charge (APC) for publication in this open access journal is 2600 CHF (Swiss Francs). Submitted papers should be well formatted and use good English. Authors may use MDPI's English editing service prior to publication or during author revisions.
