In this paper, a proactive correspondent registration mechanism is proposed for the Proxy Mobile IPv6 (PMIPv6) route optimization between the correspondent node (CN) and the mobile access gateway (MAG) on behalf of the mobile node (MN) in wireless access networks. Two scenarios are considered according to the type of CN. For the proposed mechanism, the proxy home test and the concurrent care-of...

Multicamera vehicle tracking is a necessary part of any video-based intelligent transportation system for extracting different traffic parameters such as link travel times and origin/destination counts. In many applications, it is needed to locate traffic cameras disjoint from each other to cover a wide area. This paper presents a method for tracking moving vehicles in such camera networks. The...

Packet loss in mobile IPv6 is a huge problem during mobile node handover, especially for real-time packets. When the mobile node moves from one subnet to another, it cannot receive packets that the correspondent node sent to it. This unreachable problem remains until the mobile node gets new address and sends its binding updates to inform the correspondent node about its new address. In real-ti...

The Mobile IPv6 protocol includes a route optimization mechanism that improves routing efficiency by informing correspondent nodes about the current care-of address of the mobile node. Mobile node physical location may be associated with its topologically correct IP address. Revealing the mobile node’s care-of address can therefore be used to track the mobile with certain accuracy, which compro...

Punctured Reed-Solomon (RS) and Gabidulin (G) codes over the field Fqm with locators from the subfield Fq can be represented as interleaving of m correspondent codes over the subfield Fq or can be considered as virtual interleaving of m correspondent codes over the field Fqm . Using a probabilistic unique syndrome decoder, m-interleaved or virtually interleaved codes can be decoded up to the sa...

Proxy Mobile IPv6 outperforms previous mobility protocols have been standardized by the Internet Engineering Task Force. However, Proxy Mobile IPv6 still involves the triangle routing problem in where data packets for the mobile node are delivered throughout inefficient routing paths. To address the triangle routing problem, two different Route Optimization schemes proposed that exclude the ine...

This work presents a new approach toward copy-move forgery detection based on multi-scale analysis and voting processes of a digital image. Given a suspicious image, we extract interest points robust to scale and rotation finding possible correspondences among them. We cluster correspondent points into regions based on geometric constraints. Thereafter, we construct a multi-scale image represen...

OBJECTIVE To introduce new 3-D imaging techniques to characterize shape and volume changes of the oropharyngeal space after bilateral sagittal split osteotomy (BSSO) advancement. MATERIALS AND METHODS Longitudinal cone-beam computed tomography (CBCT) scans were obtained for 20 patients undergoing BSSO advancement at three time points (T1 = presurgery, T2 = splint removal, and T3 = 1 year afte...
