Required Quality

The vertical handover decision strategy is a challenging problem to support seamless mobility in different wireless technology. The handover decision process is reported to facilitate the required Quality of Service, but bad network selection and overload condition of the chosen network fallout in handover failures. Traditional handoff techniques typically are based on single parameter and are inefficient due to superfluous handovers. In addition, existing fuzzy based handoff method reduces the handover failures but increase the computational complexity. Furthermore, the existing mobile controlled handover techniques are not suitable for heterogeneous environment. Therefore this paper focus the need of efficient, robust and flexible vertical handover technique to reduce the handover failures and design an MADM based network controlled handover that maximize QoS in heterogeneous environment

Acute Healthcare

In this current 21st-century global competitive market, employee empowerment plays a significant role in building the internal resource-based capacity of business survival towards meeting and exceeding ever-increasing market needs. The tertiary health institutions saddled with the responsibility of providing acute healthcare services significantly require effective commitment of their healthcare workers in promoting quality of service delivery towards achieving result-oriented healthcare quality assurance outcome. However, the Nigerian health sector has been characterised with diverse challenges in sustaining quality assurance due to lack of leadership commitment in empowering caregivers in the sector effectively. To a large extent, this has weakened the adequate performance of employees, and also, contributed to the observed increase in morbidity and mortality rate in the Nigerian health centres. This aim of this paper is to critically analyse the impact of employees' empowerment on the perceived quality of service delivery in the context of the Nigerian healthcare institutions.

Vertical Handover Decision (VHD) algorithms are indispensable components of forthcoming 4G heterogeneous wireless networks architecture – so as to provide requisite Quality of Service to an assortment of applications anywhere at any time, while allowing seamless roaming in highly dynamic scenarios (i.e. multitude of access network technologies that vary in bandwidth, latency, monetary cost, etc.) using Mobile Terminals (MTs) enabled with multiple access interfaces. In this article, a critical review of the existing VHD algorithms has been carried out as an effort to update the previous studies. To offer a methodical contrast, recently published VHD algorithms have been classified into four major classes depending on the key handover decision criterion used, i.e. RSS based algorithms, bandwidth based algorithms, cost function based algorithms, and the combination algorithms. Moreover, operational fundamentals, advantages, and disadvantages of exemplary VHD algorithms for each class have been presented to assess the tradeoffs between their intricacy of implementation and the efficacy.
