This book presents the design of delay-efficient packet schedulers for heterogeneous M2M uplink traffic classified into several classes, based on packet delay requirements, payload size, arrival process, etc. Specifically, the authors use tools from queuing theory to determine the delay-optimal scheduling policy. The proposed packet schedulers are designed for a generic M2M architecture and thus equally applicable to any M2M application. Additionally, due to their low implementation complexity and excellent delay-performance, they authors show how they are also well-suited for practical M2M systems. The book pertains primarily to real-time process scheduler experts in industry/academia and graduate students whose research deals with designing Quality-of-Service-aware packet schedulers for M2M packet schedulers over existing and future cellular infrastructure. Presents queuing theoretic analysis and optimization techniques used to design proposed packet scheduling strategies; Provides utility functions to precisely model diverse delay requirements, which lends itself to formulation of utility-maximization problems for determining the delay- or utility-optimal packet scheduler; Includes detail on low implementation complexity of the proposed scheduler by using iterative and distributed optimization techniques.

CP is the foremost cause of motor disability in children and affects two to five children in 1000 live births worldwide. It is been recognized as a global concern medically, socially, and economically due to the increasing financial burden to the states. About half of the children with cerebral palsy suffer a range of motion difficulties. The study aims to understand the role of orthotic devices and its efficacy in the treatment of the patient with cerebral palsy and gait improvement. An online database of Pubmed, Science Direct, Google Scholar, etc. searched to find the articles with the keywords, cerebral palsy, orthotic devices, orthosis, lower limb, and results were synthesized and narrated to explore the effectiveness of the devices on the gait pattern and quality of life of a patient with cerebral palsy. The database search was done without the barrier of dates and regions. Orthoses applied externally appear to be supported and had a diverse effect on gait depending on the type of orthosis. However, the relationship between gait pattern and AFOs and ankle properties is yet to be established. Additional research in this area is needed to complement the development of passive and active AFOs to provide larger improvements in walking capabilities.
