    Reducing Packet Overhead in Mobile IPV6

    Common Mobile IPv6 mechanisms, Bidirectional tunneling and Route optimization, show inefficient packet overhead when both nodes are mobile. Researchers have proposed methods to reduce packet overhead regarding to maintain compatible with standard mechanisms. In this paper, three mechanisms in Mobile IPv6 are discussed to show their efficiency and performance. Following...

    Variance Based Component Analysis for Texture Segmentation

    This paper presents a comparative analysis of a new unsupervised PCA-based technique for steel plates texture segmentation towards defect detection. The proposed scheme called Variance Based Component Analysis or VBCA employs PCA for feature extraction, applies a feature reduction algorithm based on variance of eigenpictures and classifies the pixels as...

    DEC: Diversity-Based Energy Aware Clustering for Heterogeneous Sensor Networks

    The clustering schemes devised so far mostly concentrate on satisfying the classic requirement of wireless sensor networks, which is energy awareness, to prolong network lifetime. On the other hand, there is a growing demand on applying heterogeneous nodes in sensor network applications, like distributed composite event detection that introduces new...

    An Adaptive Service Choreography Approach Based on Ontology-Driven Policy Refinement

    Business corporations usually require choreography of services to be dynamic and adaptable. One way for answering this demand is to develop the services having dynamic behaviors. However, it is not enough and their behaviors must be composed dynamically too. The current model such as WS-CDL has a static structure to...

    A Human-Centric Approach to Group-Based Context-Awareness

    The emerging need for qualitative approaches in context-aware information processing calls for proper modeling of context information and efficient handling of its inherent uncertainty resulted from human interpretation and usage. Many of the current approaches to context-awareness either lack a solid theoretical basis for modeling or ignore important requirements such...

    Transformation of Short-Term Spectral Envelope of Speech Signal Using Multivariate Polynomial Modeling

    Speaker transformation uses a mapping between the signal parameters derived from a set of phrases spoken by two speakers to modify the speech signal of one speaker to make it perceptually similar to that of the other speaker. In spectral warping and interpolation technique, the transformation function can be estimated...

    A Hybrid Technology Acceptance Approach For Using The E-CRM Information System In Clothing Industry

    A successful E-CRM strategy and implementation should be able to demonstrate a shift in the number of interactions from higher cost channels to lower cost electronic channels. Combining this with the ability to demonstrate either sustained or improved relationship strength levels will provide a good overall indicator of the value...

    A New Approach to Cold Start in Peer-to-Peer File Sharing Networks

    Solving free riding and selecting a reliable service provider in P2P networks has been separately investigated in last few years. Using trust has shown to be one of the best ways of solving these problems. But using this approach to simultaneously deal with both problems makes it impossible for newcomers...
