Available Bandwidth Estimation Techniques (ABETS) For An Efficient Telemedicine Content Transport Network
(IJERT, 2013-07) Kayange, Daniel; Sinde, Ramadhani; Sam, Anael
The ability to measure end-to-end Available Bandwidth (unused capacity) in the network path is useful for route selection in overlay networks, QoS verification, network management, traffic engineering and real-time resource provisioning, control flow and congestion, construction of overlay - routing infrastructure, topology building in peer to peer networks, and call admission control, dynamic encoding rate modification in streaming applications, capacity planning, intelligent routing systems, and design of transport layer protocols. This paper investigates at applying techniques and measurement of Available Bandwidth (AB) in the congestion control for the transmission of an efficient telemedicine content transport network by using an important ABETs tool like Pathload, IGI, and Pathchirp. This paper discusses measurement and simulation results of wired and wireless networks for the unused capacity in the network. The results can assist an organization or country in estimating the network bandwidth requirements depending on the ability of exchange multimedia data of an organization or country. The logistics could cater implementation of low cost telemedicine applications. The telemedicine systems could include wireless and wired medical interface and communication infrastructure. A simulation has been done to investigate the network quality of service.
Overview applications of data mining in health care: The case study of Arusha region
(IJCER, 2013-08) Diwani, Salim; Mishol, Suzan; Kayange, Daniel; Machuve, Dina; Sam, Anael
Data mining as one of many constituents of health care has been used intensively and extensively in many organizations around the globe as an efficient technique of finding correlations or patterns among dozens of fields in large relational databases to results into more useful health information. In healthcare, data mining is becoming increasingly popular and essential. Data mining applications can greatly benefits all parties involved in health care industry. The huge amounts of data generated by healthcare transactions are too complex and voluminous to be processed and analyzed by traditional methods. Data mining provides the methodology and technology to transform huge amount of data into useful information for decision making. This paper explores data mining applications in healthcare in Arusha region of Tanzania more particularly; it discusses data mining and its applications in major areas such as evaluation of treatment effectiveness, management of healthcare itself and lowering medical costs
Pathload for available bandwidth esti-mation techniques (ABETs) for an efficient telemedicine content transport network
(ResearchGate, 2013-08) Kayange, Daniel; Sam, Anael; Sinde, Ramadhani
The ability to measure end-to-end Available Bandwidth (unused capacity) in the network path is useful for route selection in overlay networks, for QoS verification, network management and traffic engineering. This paper investigates at applying techniques and measurement of Available Bandwidth (AB) in the congestion control for the transmission of an efficient telemedicine content transport network by using an important ABETs tool such as Pathload. This paper discusses measurement and simulation results of wired and wireless networks for the unused capacity in the real telemedicine network path and normal network path. The results can assist an organization or country in estimating the network bandwidth requirements depending on the ability of exchange multimedia data of an organization or country. The logistics could cater implementation of low cost telemedicine applications. The telemedicine systems could include wireless and wired medical interface and communication infrastructure.

A Survey on Dynamic Spectrum Access (DSA) and Management in Vehicular Environment: The Case Study in Tanzania
(ResearchGate, 2013) Kayange, Daniel; Ochola, Elisha; Sam, Anael; Sinde, Ramadhani
This paper describes the survey approach to building a high-quality of dynamic Spectrum access (DSA) and management in vehicular environment networks in Tanzania as one of the ways of mitigating the shortage of access. Frequency spectrum is a limited resource for wireless communications and may become congested owing to a need to accommodate the diverse types of air interface used in wireless networks. The objective of this paper is to meet these growing demands by provide a brief overview of the cognitive radio technology. The paper explains the existing work and challenges in spectrum sensing. It describes the next network functionalities: spectrum management, spectrum mobility and spectrum sharing and further explains how next network functions can be implemented.
