Article Citation - WoS: 7Citation - Scopus: 10Efficient Software Review Process for Small and Medium Enterprises(inst Engineering Technology-iet, 2007) Mishra, D.; Mishra, A.A considerable amount of software is produced world-wide by small and medium enterprises (SMEs). These organisations do not have enough resources to implement a rigorous quality plan. It has been established that reviews of various artifacts play a very important role in ensuring the quality of software. Traditional review methods are rigorous and their implementation is cumbersome for SMEs. A new review process which is easy to implement and requires almost no documentation is introduced. It is based on reviewers' efforts to produce high-quality software while minimising the inspection cost. Additionally, people who are conducting this review need not be present at the same place during most phases of the review process. This process has been successfully implemented in a CMM level 3 software development company intending to achieve CMMI level 5 and results are found to be quite encouraging.Article Citation - WoS: 29Citation - Scopus: 36Massive Mimo Systems for 5g: a Systematic Mapping Study on Antenna Design Challenges and Channel Estimation Open Issues(inst Engineering Technology-iet, 2021) Benzaghta, Mohamed; Rabie, Khaled M.The next generation of mobile networks (5G) is expected to achieve high data rates, reduce latency, as well as improve the spectral and energy efficiency of wireless communication systems. Several technologies are being explored to be used in 5G systems. One of the main promising technologies that is seen to be the enabler of 5G is massive multiple-input multiple-output (mMIMO) systems. Numerous studies have indicated the utility of mMIMO in upcoming wireless networks. However, there are several challenges that needs to be unravelled. In this paper, the latest progress of research on challenges in mMIMO systems is tracked, in the context of mutual coupling, antenna selection, pilot contamination and feedback overhead. The results of a systematic mapping study performed on 63 selected primary studies, published between the year 2017 till the second quarter of 2020, are presented. The main objective of this secondary study is to identify the challenges regarding antenna design and channel estimation, give an overview on the state-of-the-art solutions proposed in the literature, and finally, discuss emerging open research issues that need to be considered before the implementation of mMIMO systems in 5G networks.Article Citation - WoS: 29Citation - Scopus: 37Metrics Suite for Maintainability of Extensible Markup Language Web Services(inst Engineering Technology-iet, 2011) Baski, D.; Misra, S.The eXtensible Markup Language (XML) web services are emerging as the de-facto mechanism for exchanging structured information between applications. The large popularity and acceptance of web services led the developers to adopt the best practices of web service implementation and to find the ways for managing and maintaining web services more effectively. Maintainability, one of the important factors, which affects the quality of XML web services, can be controlled by the proper software metrics that are specifically designed and developed for it. In this paper, we present a suite of metrics to evaluate the quality of the XML web service in terms of its maintainability. The present suite of metrics includes: data weight of a web service description language, distinct message ratio metric, message entropy metric and message repetition scale metric. All the proposed metrics have been evaluated theoretically and validated empirically. A comparative study with similar measures proves the worth of the metric suite.Article Citation - WoS: 20Citation - Scopus: 25Framework for Evaluation and Validation of Software Complexity Measures(inst Engineering Technology-iet, 2012) Misra, S.; Akman, I.; Colomo-Palacios, R.This study proposes a framework for the evaluation and validation of software complexity measure. This framework is designed to analyse whether or not software metric qualifies as a measure from different perspectives. Unlike existing frameworks, it takes into account the practical usefulness of the measure and includes all the factors that are important for theoretical and empirical validation including measurement theory. The applicability of the framework is tested by using cognitive functional size measure. The testing process shows that in the same manner the proposed framework can be applied to any software measure. A comparative study with other frameworks has also been performed. The results reflect that the present framework is a better representation of most of the parameters that are required to evaluate and validate a new complexity measure.
