Wireless ad-hoc networks consist of mobile nodes forming a dynamically changing topology without any infrastructure. Multicasting in a wireless ad-hoc network is difficult and challenging. In this paper we propose a novel protocol, Wireless Ad-hoc Real-Time Multicasting (WARM), for multicasting real-time (CBR and VBR) data among nodes in a wireless ad-hoc network. The protocol is distributed, h...

Modern systems, such as web services, need to be selfhealing, which means capable of surviving autonomously the occurrence of faults, still managing to provide the desired functionality. Designers of such systems need tools helping them to assess beforehands the self-healability of their system, but as a first step towards such tools, one needs to better define what self-healability precisely m...

Hermes is a middleware system for design and execution of activity-based applications in distributed environments. It supports mobile computation as an application implementation strategy. While middleware for mobile computing has typically been developed to support physical and logical mobility, Hermes provides an integrated environment where application domain experts can focus on designing a...

The proposal of our research work is to develop a reconfigurable hardware to flourish an enhanced self-healing ability for sensor nodes using FPGA. Emphasizing the engineering wing, the Wireless sensor network plays a prominent role of successful applications. When there is an identification of frailty that is failing in node, it is commonly discarded and network is reorganized to ensure the no...

Self-repair is essential to all living systems, providing the ability to remain functional in spite of gradual damage. In the context of self-assembly of self-repairing synthetic biomolecular systems, recently Winfree developed a method for transforming a set of DNA tiles into its selfhealing counterpart at the cost of increasing the lattice area by a factor of 25. The overall focus of this pap...

1 Based on "The Time-Controlled Clustering Algorithm for Optimized Data Dissemination in Wireless Sensor Networks", by S. Selvakennedy and S. Sinnappan which appeared in The IEEE Conference on Local Computer Networks, 2005. © 2005 IEEE. Abstract—Wireless sensor networks afford a new opportunity to observe and interact with physical phenomena at an unprecedented fidelity. To fully realize this v...

This paper presents a genetic algorithm based method to solve the capacity and routing assignment problem arising in the design of selfhealing networks using the Virtual Path (VP) concept. Past research has revealed that Preplanned Backup Protection method and the Path Restoration scheme can provide a best compromise on the reserved spare capacity and the failure restoration time. Base on a set...

Towards the complete vision of smarter distribution grid, advanced distribution automation system (ADAS) is one of the major players in this area. In this scope, this paper introduces a generic strategy for cost-effective implementation and evaluation of ADAS. Along with the same line, fault location, isolation and service restoration (FLISR) is one of the most beneficial and desirable applicat...

Wireless mesh networks (WMNs) have became the focus of many researchers as a promising technology for a broad range of applications due to their self-organizing, self-configuring and selfhealing capability, in addition to their low equipments and deployment cost. WMNs are not mobile ad hoc networks (MANETs); instead they can be considered as a superset of traditional mobile ad hoc networks (MAN...

Concrete is susceptible to cracking owing to drying shrinkage, freeze-thaw cycles, delayed ettringite formation, reinforcement corrosion, creep and fatigue, etc. Since maintenance and inspection of concrete infrastructure require onerous labor and high costs, self-healing of harmful cracks without human interference or intervention could be of great attraction. The goal of this study is to expl...
