Traffic engineering capabilities defined in MPLS enables QoS online routing of LSPs. In this paper we address issues of network survivability in online routing. We define a new link weight LFL (Lost Flow in Link) that can be applied for dynamic routing of LSPs in survivable MPLS network. We propose to use the LFL metric as a “scaling factor” for existing dynamic routing algorithms that make use...

The expected number of transmission (ETX) represents a routing metric that considers the highly variable link qualities for a specific radio in Wireless Sensor Networks (WSNs). To adapt to these differences, radio diversity is a recently explored solution for WSNs. In this paper, we propose an energy balancing metric which explores the diversity in link qualities present at different radios. Th...

Wireless networks have many dimension devices which are connected by wireless communication links. The links are most often implemented with digital packet radios. Because each radio link has a limited communications range, many pairs of nodes cannot communicate directly, and must forward data to each other via one or more cooperating intermediate nodes. We will often use „time count metric‟ to...

Distance metric has an important role in many machine learning algorithms. Recently, metric learning for semi-supervised algorithms has received much attention. For semi-supervised clustering, usually a set of pairwise similarity and dissimilarity constraints is provided as supervisory information. Until now, various metric learning methods utilizing pairwise constraints have been proposed. The...

We introduce new reliability definitions for bit and check nodes. Maximizing global reliability, which is the sum reliability of all bit nodes, is shown to be equivalent to minimizing a decoding metric which is closely related to the maximum likelihood decoding metric. We then propose novel bit-flipping (BF) decoding algorithms that take into account the check node reliability. Both hard-decisi...

Software reliability is an important quality attribute, often evaluated as either a function of time or of system structures. The goal of this study is to have this metric cover both for component-based software, because its reliability strongly depends on the quality of constituent components and their interactions. To achieve this, we apply a convolution modeling approach, based on components...
