Disasters are characterized by the destruction of infrastructure that support communication, rendering communication impossible. This project seeks to design and develop a mobile application to create an opportunistic network using mobile phones as nodes, to identify the location of victims and to establish communication between rescuers and victims. The system was designed using Android application...
This paper argues that the privacy concerns that are associated with national identification systems is because of the failure of various countries to implement national identification systems with a strong privacy theory backing the implementation. This work is therefore aimed at addressing the privacy concerns of those countries debating national identification system adoption. Furthermore, the...
Adequate generation capacity to meet the increasing demand of electricity has remained the main focus of both developed and developing economies. In order to maintain the safety of generation and distribution systems, constant load shedding is employed to maintain equilibrium between overall generation and total demand per unit period. This paper proposes a distribution management algorithm to micro-load...
Current research works have looked at improving the IPsec secured VoIP by arbitrarily increasing bandwidth which is a very limited resource and cannot just be increased in real environments except under laboratory conditions. Also, in most earlier works, codec has been kept constant and the IPsec impact analysed. The results of such works undoubtedly show the devastating impact IPsec has on VoIP which...
Security of data or information is one of the challenges faced in the wireless sensor networks (WSNs) and there have been quite a number of encryption protocols such as TinySec, C-Sec and Zigbee that have achieved this feat. However the drawbacks of these protocols is that there are overheads with respect to packet size, energy and time thus affecting the limited resources that the sensor nodes have...
We have over the past three years been working on the feasibility of Opportunistic Cloud Services (OCS) for enterprises. OCS is about enterprises strategically contributing and utilizing spare IT resources as cloud services. One of the major challenges that such a platform faces is data security and trust management issues. This paper presents a trust management system for OCS platforms. It models...
This paper analyzes the decision-making problem confronting SMEs considering the adoption of cloud computing as an alternative to in-house computing services provision. The economics of choosing between in-house computing and a cloud alternative is analyzed by comparing the total economic costs of the two options assuming the quality of service is identical across the options. The decision-making...
Opportunistic Cloud Computing Service (OCCS) is a social network approach to the provisioning and management of cloud computing services for enterprises. The OCCS network may suffer from the free riding problem where members are selfish and will only want to use services on the platform without ever contributing resources. It may also suffer from resource wastage from members or external entities...
