Existing software complexity metrics do not adequately address the unique architectural patterns of Laravel. This research, therefore, solves this problem by proposing a suite of novel complexity metrics for Laravel software. The metric definition employs the Entity-Attribute-Metric-Tooling (EAMT) model. These proposed metrics are designed to asses...

An alert correlation is a high-level alert evaluation technique for managing large volumes of irrelevant and redundant intrusion alerts raised by Intrusion Detection Systems (IDSs).Recent trends show that pure intrusion detection no longer can satisfy the security needs of organizations. One problem with existing alert correlation techniques is tha...

Effective use of sensor nodes’ batteries in wireless sensor networks is critical since the batteries are difficult to recharge or replace. This is closely connected to the networks’ lifespan since once the battery is used up, the node is no longer useful. The entire network will not function if 60 to 80% of the nodes in it have completely depleted...

In software engineering, software complexity measures how complicated it is to design, test, maintain, and comprehend a system or a program. Metrics have been appreciated over time as a measure of various attributes of software products. Some of the most well-known languages for scientific, object-oriented, and imperative programming are Python, Ja...

The extension of the sensor node's life span is an essential requirement in a Wireless Sensor Network. Cluster head selection algorithms undertake the task of cluster head election and rotation among nodes, and this has significant effects on the network's energy consumption. The objective of this paper is to analyze existing cluster head selection...

Model-Driven Development and the Model-Driven Architecture paradigm have in the recent past been emphasizing on the importance of good models. In the Object-Oriented paradigm one of the key artefacts are the Statechart diagrams. Statechart diagrams have inherent complexity which keeps increasing every time the diagrams are modified, and this comple...

Open-source enterprise resource planning (ERP) software has become a preferred alternative for modern organizations due to its affordable cost, availability and ease of access. Open-source software allows access to customizable code which in most instances may have security loop holes due to the nature of its releases. The study is motivated by nee...

Mobile Ad-hoc networks (MANETs) are unique type of wireless networks that are infrastructureless and with no centralised management. Nodes in MANETs act as both routers and hosts. The nodes are free to join and leave the network. Routes are established by use of special routing protocols. Mobility of nodes makes the network topology constantly dyna...

MANETs Communication relies on special routing protocols that make security a challenging endeavor. MANETs are open to a range of active and passive attacks; black hole attack is an active attack affects the network layer. Cooperative black hole attack is a form of denial of service attack comprised of more than one black hole nodes that collaborat...

The advent of mobile technology led to the emergence of Mobile Ad-hoc networks (MANETs). These networks have no infrastructure and central authority. Nodes in MANETs act as both routers and hosts. MANET nodes join and leave the network at will making the network topology dynamic. MANETs are prone to both passive and active security attacks. Blackho...

Enormous development has been experiences in the field of text and image extraction and classification. This is due to large amount of image data that is generated as a result of document sharing for collaborative software development and electronic storage of design documents. One of the recent technique for analyzing large dataset and discover un...

With the rapid development of mobile technology and subsequent mass adoption of mobile devices, mobile crowdsensing (MCS) has gained a lot of research attention. In MCS systems, trust is a key focus in the overall improvement in the participant uptake of the sensing tasks. The trust-based scheme of MCS is studied to predict the damage level, the sc...

Even though most organizations are using enterprise resource planning applications, very few people understand the underlying interoperability nature within them. Interoperability is the ability of systems to provide services to and accept services from other systems, and to use the services exchanged so as to operate together in a more effective m...

Enterprise resource planning (ERP) is a class of integrated software that uses software technologies to implement real-time management of business processes in an organization. ERPs normally cut across organizations, making them large and complex. Software researchers have for many years established that complexity affects software quality negative...

The burden of preeclampsia has been a major concern worldwide both in developed and developing countries, making its prevention and management a major concern. Although motherhood is a fulfilling experience in society, it is connected to ill-health in some women, leading to maternal morbidity and mortality. The United Nations' Sustainable Developme...

__________________________________________________________________________________________ Abstract Blood pressure is one of the measurements that is taken during antenatal care visits. Though motherhood is a fulfilling experience in society, it is connected to ill-health and even death in some women leading to maternal morbidity and mortality due...

Healthcare business processes are complex due to the many decisions and procedures captured, are highly dynamic, increasingly multidisciplinary and ad hoc which makes it difficult to achieve any meaningful improvement through control flow improvement. This study aims at developing and validating a method for healthcare business process improvement...

In the recent years, data mining has been utilized in education settings for extracting and manipulating data, and for establishing patterns in order to produce useful information for decision making. There is a growing need for higher education institutions to be more informed and knowledgeable about their students, and for them to understand some...

Electronic government (e-government) provides a common infrastructure and direction across the public sector. It enhances collaboration within and among public sector organizations between Government and the business community, and between government and their citizens. Successful e-government depends on how well the targeted users (citizens) make...

There is a general consensus that governments, businesses and all individuals need to harness the power of Information and Communication Technology (ICT) and ICT enabled services for wider access and improved welfare standards.
