PReSENt: A Collaboration Framework for Resource Sharing in Wireless Mesh Networks

Many protocol particulars developed for the wireless mesh networks, such as multi-path routing, channel assignment, topology control, assume that a network-wide collaboration is available to establish connections to the network outside. However, the collaboration can be easily discouraged in the presence of selfish behaviors, referred to as free-riding. In this paper, we propose a framework, PReSENt, to promote and make more secure the practices of collaboration among nodes by securing a compensation to the collaboration. When the PReSENt is enabled in wireless mesh networks, a node accumulates credits, an amount quantifying its resource provision when it provides its resource for other nodes. The nodes consuming the resource publish rewards, an amount quantifying their resource usage. The credits are used to guarantee the resource sharing for the provider from the customers in the future, whose amount is proportional to its relative contribution to the network-wide collaboration. The rewards are used to validate their corresponding credits in order to prevent false accumulations of the credits in selfish nodes. We formally define the underlying security model of the PReSENt and prove that the PReSENt is secure in the random oracle model. We then implement the PReSENt in J-Sim to illustrate its operational behaviors with respect to correct and secure resource sharing.

A dependency taxonomy for agile software development projects

Agile software development is designed to achieve collaborative software development. A supporting pillar of collaboration is effective coordination, which is necessary to manage dependencies in projects. Understanding the dependencies arising in agile software development projects can help practitioners choose appropriate coordinative practices from the large number of practices provided by the various agile methods. To achieve this understanding, this article analyses dependencies in three typical cases of co-located agile software development and presents the dependencies as a taxonomy with decision rules for allocating dependencies into categories. Findings show that knowledge, process, and resource dependencies are present, with knowledge dependencies predominant. In addition, there are agile practices with a coordinative function that address multiple dependencies in these agile software development projects. These practices would be a good choice for coordinating a project and supporting collaboration in agile software projects.     

Resource collaboration system based on dynamic user preference and context

In a ubiquitous computing environment, service composition and collaboration among heterogeneous resources are required, thus, an infrastructure that supports these requirements is an essential factor in seamless service delivery. In this environment, users hope to get a variety of customized services by using only an individual mobile device. But the resource of the mobile device has limitations such as tiny display screens, limited input, less powerful processors, and limited storage. Moreover each user situation is different and user preferences are also various. Therefore it is one of new issues to provide a customized service for a user through resource collaboration based on various user preference and situation. To solve this issue, this paper proposes a resource collaboration system which infers customized resources for composing a user required service and collaborative with selected resources. For our collaboration system, this paper proposes the method to infer resources based on the context and user preferences including dynamic change of the preference. This paper also shows a reasonable execution environment for the proposed system through the performance evaluation in server-client and peer-to-peer environments.

The design and development of a computerized tool support for conducting senior projects in software engineering education

This paper presents a computerized tool support, the Meetings-Flow Project Collaboration System (MFS), for designing, directing and sustaining the collaborative teamwork required in senior projects in software engineering (SE) education. Among many schools’ SE curricula, senior projects serve as a capstone course that provides comprehensive training in collaborative project development. With the focus on collaboration training, instructors of senior projects often address issues that include how to encourage collaboration and ensure that collaborative efforts are sustained throughout the project’s development. In order to help resolve these issues, the MFS takes a holistic approach. The meetings-flow concept that undergirds the MFS introduces a novel macro-level and meeting-oriented group process to guide the proceeding of the project’s collaborative work. The design of the MFS facilitates a computerized environment that helps to institutionalize and monitor such a group process. In introducing the MFS, we focus initially on the elaboration of the concept and design, after which we present and validate the system implementation and usage. We also evaluate the MFS and receive a positive result with respect to the educational issues raised in this paper. Finally, we comparatively summarize the MFS to discuss its values and the role it plays in CSCL (computer supported collaborative learning) and PBL (project-based learning) of SE education.     

A Petri Net Approach to Support Resource Assignment in Project Management

Petri nets have long been used in modeling and simulating project execution because of their great capability to describe concurrent activities and simulate the evolvement of processes. Although a number of extended Petri net models have been proposed to model and simulate resource sharing and activity dependence in projects, none of them has ever included a resource assignment mechanism into their models. Because resource assignments influence how limited resources are allocated among conflicting activities, they may heavily affect the availability of resources and the execution of projects. Therefore, a model without considering resource-sharing and resource assignment strategies may lead to a misunderstanding about project scheduling, resource consumption behaviors, and estimated project time. Accordingly, this paper proposes a new extended Petri net model that can describe how resources are shared and assigned among concurrent activities of multiple projects. The proposed model is named as resource assignment Petri net (RAPN), which extends an object composition Petri net with new places, transitions, attributes, and firing rules to model resource-sharing and resource assignment strategies. Finally, we prove that RAPN can correctly model the resource consumption behaviors of projects and can correctly compute the total elapsed time of projects.     

An exact algorithm for an integrated project staffing problem with a homogeneous workforce

When scheduling projects under resource constraints, assumptions are typically made with respect to the resource availability. In resource scheduling problems important assumptions are made with respect to the resource requirements. As projects are typically labour intensive, the underlying (personnel) resource scheduling problems tend to be complex due to different rules and regulations. In this paper, we aim to integrate these two interrelated scheduling problems to minimise the overall cost. For that purpose, we propose an exact algorithm for the project staffing with resource scheduling constraints. Detailed computational experiments are presented to evaluate different branching rules and pruning strategies and to compare the proposed procedure with other optimisation techniques.     

A social recommendation system for academic collaboration in undergraduate research

Academic collaboration plays an important role in undergraduate research. Current methods rely on offline social contacts for undergraduate students to collaborate with academic staff members in universities and research institutions. In big data era, it is difficult for undergraduate students to find suitable research project opportunities and supervisors to work with. This paper proposes a social recommendation system for undergraduate students to find research project opportunities and work with research project teams on an academic collaboration network. The proposed recommendation method integrates relevance, connectivity, and quality modules, where profiles of undergraduates are constructed with their self‐claimed information, research activities (e.g., studying and reading research publications and reading research projects), and social connections in the academic collaboration network. Suitable research projects are recommended based on the undergraduates' profiles. Experiments are conducted, and the results have shown that the proposed social recommendation system can facilitate undergraduates' selection of research projects.
