Abstract: An optimal selection of a WSN topology protocol and a suitable lightweight cipher algorithm is a highly important task, whose success ensures both the maximum utilization and the security of a wireless sensor network. This paper presents a method to determine the optimal combination of a WSN topology protocol and a lightweight cipher algorithm in the context of power consumption throughout an entire network. A selection method based on multi-attribute decision-making methods is proposed. These methods, used for the first time in a study of sensor networks, provide a ranking of the optimal combinations of topologies and encryption algorithms that meet the requirements of wireless sensor networks such as authentication, data integrity, reliability, availability, confidentiality, and energy efficiency.

Keywords: Ciphers, Multi-criteria decision-making, Network topology, Wireless sensor networks.
