Development of Multilevel Distributed Database Architecture for Solving (GSM) Centralized Database Accessing Problem in Nigeria

Telecommunication is the basis of economic and political growth of any society. Since the advent of GSM in Nigeria, different operator have been battling with diverse challenges which erupted as a result of GSM growth and increased in number of GSM users. These challenges result in calls delay and poor quality of service which can be link to central database system. In this research work, a multilevel distributed database architecture for GSM network in Nigeria was developed and propose. It explores the use of the analytical model and numerical calling process algorithms for each location. The call arrival rate traffic to a database system is determine using mapping process ranging from state to region and finally to the center.

Analysis of algorithms in long term evolution (LTE) network

Long Term Evolution (LTE) network is a wireless network developed for fast and effective communication among internet users for resource accessing and sharing. Several scheduling algorithms have been proposed in attempts by researchers to solve the problem of scarcity of radio resources available to network users. Determining the best scheduling algorithm based on chosen metrics is an interesting issue of research. In this paper thus, we present a comparative analysis of these scheduling algorithms for resource management in Long Term Evolution (LTE) network. The algorithms; [Proportional Fair (PF), Exaggerated Earliest Deadline First (E2DF), Modified-Largest Weighted Delay First (M-LWDF) and Exponential Proportional Fair (EXP-PF)], were simulated, then compared using standard metrics such as; Block Error Rate (BLER), Spectral Efficiency, Throughput and Fairness with the aim of determining the best performing scheduling algorithm with respect to each of the metrics.Keywords: Wireless Network, Long Time Evolution Network, Scheduling, Computer Network
