Broadcasting is an ad hoc network critical function component, and, in many deployments, making it power efficient is extremely important. Current power adaptive approaches proposed for broadcasting can be grouped into (a) centralized or omniscient schemes, and (b) decentralized or localized schemes. Due to the absence of global information, localized(More)
A triangulation-based coverage scheme using mobile sensor nodes (MSNs) has several applications in localization, 3D imaging and coordinated search operation. In this work, we introduce an efficient failure-tolerant mobile traversal algorithm (FTMTA) that provides a triangulation-based coverage of a field. FTMTA employs <i>N</i> MSNs such that, upto <i>N</i>(More)
In harsh outdoor terrains like disaster areas and urban toxic regions, optimal placements of static sensor nodes might not be possible, leading to possible incomplete coverage of the region. In such situations, mobile sensor nodes (MSNs) might be a better option and a significantly fewer number of nodes are required than their static counterparts. A(More)
In a Triangulation-based coverage scheme, a group of three mobile sensor nodes (MSN) position themselves to form an equilateral triangle for a desired period of time. Such a scheme has several applications in localization, environmental monitoring and coordinated target tracking. In this work, we introduce an efficient mobile traversal algorithm (MTA) that(More)
Social networking has emerged as a powerful paradigm that connects people of similar interests. It has shown to be effective in routing queries in referral systems and cellular networks, and also in the production of frequently asked questions (FAQ) repository. In this paper, we extend its applicability to dispatch applications as part of fulfilling problem(More)
In many network and IT systems, users submit loosely-defined (or fuzzy) requests to obtain answers, solutions or resources. In this paper, we focus on trouble-shooting problem tickets in an IT service management system. In such a system, problems are typically reported using vague user-generated descriptions of the symptoms (e.g., ‘my email is not(More)
Several variations of synchronous parallel simulated annealing (PSA) were applied to solve the static lightpath establishment wavelength selective cross-connect network operation problem for a WDM network. The goal was to find high-quality solutions to determine the efficiency of the dynamic routing and wavelength assignment algorithms. Multiple parallel(More)
