“…This metric is based on a partitioned module dependency graph and computed by the difference of the average inter-and intra-connectivity of the partitions. M4 Allen and Khoshgoftaar [3,4,2] propose an informationtheory based approach to define coupling and cohesion metrics. Opposed to the former count-based measures, their definitions are based on the entropy in a module interconnection graph, which accounts for patterns in the relationships.…”

Long-living software systems are sustainable if they can be cost-efficiently maintained and evolved over their entire lifecycle. The quality of software architectures determines sustainability to a large extent. Scenario-based software architecture evaluation methods can support sustainability analysis, but they are still reluctantly used in practice. They are also not integrated with architecture-level metrics when evaluating implemented systems, which limits their capabilities. Existing literature reviews for architecture evaluation focus on scenario-based methods, but do not provide a critical reflection of the applicability of such methods for sustainability evaluation. Our goal is to measure the sustainability of a software architecture both during early design using scenarios and during evolution using scenarios and metrics, which is highly relevant in practice. We thus provide a systematic literature review assessing scenario-based methods for sustainability support and categorize more than 40 architecture-level metrics according to several design principles. Our review identifies a need for further empirical research, for the integration of existing methods, and for the more efficient use of formal architectural models.

“…Several works apply information theory to tackle non-security related issues such as measuring the complexity of software [18] and allocating resources of data storage systems [22]. In contrast to these work, we propose a set of conditional entropy metrics to detect SQLI attacks at the client-side.…”

“…Cohesion [3] is a measure of how strongly-related is the functionality expressed by the source code of a software module. Methods of measuring cohesion vary from qualitative measures classifying the source text being analyzed to quantitative measures which examine textual characteristics of the source code to arrive at a numerical cohesion score.…”

Abstract-The objective of this work is to reduce energy consumption of source programs written in C. The underlying technique employs code transformation which focuses on cohesion. Four classes of transformations will be considered: function, loop optimization, control structure, and operator. Code transformation is evaluated by effectiveness, efficiency, space complexity, number of instructions executed, number of pages, size of memory page allocated, and energy consumption. The results suggest that different cohesion level will affect the energy consumption. Moreover, different types of source code yield different energy consumptions based on cohesion measures.
