MPKMS: A Matrix-based Pairwise Key Management Scheme for Wireless Sensor Networks

Due to the sensitivity of the Wireless Sensor Networks (WSN) applications and resource constraints, authentication and key management emerge as a challenging issue for WSN. In general, various approaches have been developed for the key management in WSN. This paper has come up with a new robust key pre-distribution scheme using random polynomial functions and matrix. This new proposed scheme significantly increases the storage efficiency and provides resilience to network against node capture by using random prime numbers, polynomial functions and matrix properties. The effectiveness of the scheme is demonstrated through a security analysis and comparison with the existing schemes

Dynamic Prioritization of Path for Quality-of-Service Differentiation in Multi-Priority Traffic

The emergence of value added services relying on a higher interactivity has altered the requirements of current transport network. Diverse traffic classes are processed by a large-scale optical network, imposing a more efficient utilization of their network infrastructure resources. Such services generally cross multiple domains, but inter-domain path computation algorithms still have some limitations. This paper describes a priority based path computation algorithm to meet all QoS requirements with the available capacity. The proposed algorithm increases the rate of successful replies while minimizing the blockage in network. The dynamic traffic is classified into high and low priority, so it improves emergency response in network

Fair and Inclusive Participatory Budgeting: Voter Experience with Cumulative and Quadratic Voting Interfaces

Cumulative and quadratic voting are two distributional voting methods that are expressive, promoting fairness and inclusion, particularly in the realm of participatory budgeting. Despite these benefits, graphical voter interfaces for cumulative and quadratic voting are complex to implement and use effectively. As a result, such methods have not seen yet widespread adoption on digital voting platforms. This paper addresses the challenge by introducing an implementation and evaluation of cumulative and quadratic voting within a state-of-the-art voting platform: Stanford Participatory Budgeting. The findings of the study show that while voters prefer simple methods, the more expressive (and complex) cumulative voting becomes the preferred one compared to k-ranking voting that is simpler but less expressive. The implemented voting interface elements are found useful and support the observed voters' preferences for more expressive voting methods. *Comment: 8 pages, 3 figure

VoteLab: A Modular and Adaptive Experimentation Platform for Online Collective Decision Making

Digital democracy and new forms for direct digital participation in policy making gain unprecedented momentum. This is particularly the case for preferential voting methods and decision-support systems designed to promote fairer, more inclusive and legitimate collective decision-making processes in citizens assemblies, participatory budgeting and elections. However, a systematic human experimentation with different voting methods is cumbersome and costly. This paper introduces VoteLab, an open-source and thoroughly-documented platform for modular and adaptive design of voting experiments. It supports to visually and interactively build reusable campaigns with a choice of different voting methods, while voters can easily respond to subscribed voting questions on a smartphone. A proof-of-concept with four voting methods and questions on COVID-19 in an online lab experiment have been used to study the consistency of voting outcomes. It demonstrates the capability of VoteLab to support rigorous experimentation of complex voting scenarios

A Polynomial-based Pairwise Key Pre-distribution and Node Authentication Protocol for Wireless Sensor Networks

Continuous advances in the areas of sensor networks have made wireless sensor networks (WSNs) attractive for wide variety of applications, with vastly varying requirements and characteristics. As data sensed by nodes usually contains sensitive information, adherence to data protection requirements is vital in WSNs. This paper introduces a new robust key pre-distribution key management scheme using random polynomial functions and a matrix. The proposed mechanism significantly increases storage efficiency and enhances network resilience against node capture. The effectiveness of the mechanism is demonstrated by security analysis and a comparison to existing schemes

Implementation a Medical Simulation Curriculum in Emergency Medicine Residency Program

Applying simulation in medical education is becoming more and more popular. The use of simulation in medical training has led to effective learning and safer care for patients. Nowadays educators have confronted with the challenge of respecting patient safety or bedside teaching. There is widespread evidence, supported by robust research, systematic reviews and meta-analysis, on how much effective simulation is. Simulation supports the acquisition of procedural, technical and non-technical skills through repetitive practice with feedbacks. Our plan was to induct simulation in emergency medicine residency program in order to ameliorate our defects in clinical bedside training. Our residents believed that simulation could be effective in their real medical practice. They mentioned that facilitators’ expertise and good medical knowledge, was the strongest point of the program and lack of proper facilities was the weakest
