Connection admission control and packet scheduling for IEEE 802.16 networks

Includes bibliographical references.The IEEE 802.16 standard introduced as one of the Wireless Metropolitan Area Networks (WMAN) for Broadband Wireless Access (BWA) which is known as Worldwide Interoperability for Microwave Access (WiMAX), provides a solution of broadband connectivity to areas where wired infrastructure is economically and technically infeasible. Apart from the advantage of having high speeds and low costs, IEEE 802.16 has the capability to simultaneously support various service types with required QoS characteristics. ... While IEEE 802.16 standard defines medium access control (MAC) and physical (PHY) layers specification, admission control and packet scheduling mechanisms which are important elements of QoS provisioning are left to vendors to design and implement for service differentiation and QoS support

Wireless Mesh Networks Based on MBPSO Algorithm to Improvement Throughput

Wireless Mesh Networks can be regarded as a type of communication technology in mesh topology in which wireless nodes interconnect with one another. Wireless Mesh Networks depending on the semi-static configuration in different paths among nodes such as PDR, E2E delay and throughput. This study summarized different types of previous heuristic algorithms in order to adapt with proper algorithm that could solve the issue. Therefore, the main objective of this study is to determine the proper methods, approaches or algorithms that should be adapted to improve the throughput. A Modified Binary Particle Swarm Optimization (MBPSO) approach was adapted to improvements the throughput. Finally, the finding shows that throughput increased by 5.79% from the previous study

Informing telehealth public policy: Lessons learned from Virginia Telehealth usage pre-and post-March 2020

The enactment of Waiver 1135, in response to the COVID-19 pandemic, enabled healthcare systems to deliver care via telehealth. A descriptive analysis of the impact of the implementation of Waiver 1135 on increasing access to care in Virginia was conducted. Guided by Andersen’s Behavioral Model of Health Service Use (BMHSU) theory, this study used a longitudinal, monthly-level data from the Virginia’s All Payers Claim Database to examine telehealth utilization rates between January 2019 and December 2020. Observations in insurance coverage, healthcare clinicians role and specialty and geographic location were all examined. Results suggest that while Virginia’s overall volume of telehealth services increased post Waiver 1135, contextual factors outside of payment parity negatively impacted its use for rural Virginians. This macro-level study provides a population level examination of Virginia’s telehealth utilization which can inform post pandemic policy agendas
