Abstract This paper has proposed a user-density-based coverage optimization technique for ultra-dense cellular networks. Antenna tilting is a promising coverage optimization technique to be used in 5G networks that significantly improve the signal to interference plus noise ratio (SINR) by choosing the appropriate angle of tilt. In this paper, the cellular coverage has been optimized for scattered user densities/user-hotspots using an adaptive antenna tilting mechanism that steers the beams towards the temporal hot spot in the coverage area. The proposed method has the competence to improve the desired SINR level and coverage area for a group of the user rather than a single user. In this work, a reinforcement learning (RL) algorithm has been implemented to optimize the tilt angle. The performance of the proposed technique has been evaluated in the simulation platform considering a three-sectored multicellular mobile network where the groups of user clusters are distributed randomly. The result confirms the improvement in RSS and SINR value in the group of users having high density with maximum user satisfaction.

Payment Services

Business is transforming at an exponential rate and mobile technology is considered to be a key driver in this economic revolution. Despite the efforts of many businesses in making extensive investments in resources to enhance service experience, long-term post-adoption of mobile payment services by consumers still remains an elusive dream. In particular, researches that align South African customers value perceptions of M-payment usage are scarce. It appears then, that if service providers cannot retain users and facilitate continuance usage along M-payment platforms; they might fail to recover the initial development costs and eradicate the valuable gains derived from turning the M-payment story into a winning success. Therefore, since M-payment post-adoption has not been as rapid or widespread as expected, this study aimed to examine consumers perceptions of M-payment value and the corresponding influence on e-service trust, user satisfaction and continuance intention to use M-Payment platforms. The study followed a quantitative survey approach in which data were collected from a sample of 269 M-payment users in South Africa. Structural Equation Modelling software Smart PLS was applied to ascertain the model fit. The results of this study found strong support for positive and significant relationships between value, trust, satisfaction and continuance intentions. Service providers are challenged to utilise value and trust-formation elements as the central differentiation factors which unsurprisingly impact on satisfaction evaluations and ultimately, the users willingness to continue enjoying the M-payment service experience into the future. Thus, the confluence between financial institutions, mobile network operators as well as businesses is compelled to give prominence toward creating holistic value-based user experiences along the mobile platform.

In this study, we proposed a conceptual architecture of web personalization based on subject taxonomy tree and click-through analyses in order to improve the browsing efficiency and user satisfaction. In order to construct user profile, a hierarchal subject taxonomy tree of travel information was built. This tree has five attributes which represent the interests of a single user. Each user has his profile for generating personal categories while searching. The system then adjusts user profiles according to each user’s browsing behavior in order to learn different interests of each user. Textual data in Chinese travel web sites are used for experimental data and a prototype system is implemented in order to evaluate the proposed architecture. The result shows that personal classification is able to improve the outcome of browsing efficiency and user satisfaction on web search.

Wireless Mobile Network

In the current wireless network technology, the most important research is Ad-hoc, and the most promising is the WSN. Ad-hoc which develops on the basis of packet radio network is a wireless mobile network with self-organizing, peer to peer and multi-hop. WSN combines Ad-hoc and sensor technology to collaboratively perceive, collect and process the message of sensing objects in the coverage area of network, and send to the viewer.
