Mobile IPv6 has been designed by the IETF to provide mobility to the Internet. With mobility a user can move and change his point of attachment to the Internet without losing his network connections. If Mobile IPv6 was deployed on the Internet, typically Correspondent Nodes would be large servers of current content providers. These large servers have thousands of clients and in such scenario ma...

This paper proposes an efficient correspondent registration mechanism to reduce the signaling overhead for the Proxy Mobile IPv6 (PMIPv6). In the proposed mechanism, the signaling overhead for the proxy home test via local mobility anchor (LMA) is eliminated in case of refreshments for the correspondent registration. Therefore, through the proposed mechanism, the burden of tunnels between mobil...

In this paper, we propose an adaptive mobility management scheme for minimizing signaling costs in Hierarchical Mobile IPv6 (HMIPv6) networks. In our proposal, if the mobile node’s mobility is not local, the mobile node sends location update messages to correspondent nodes in the same way as Mobile IPv6 (MIPv6). After the creation of a spatial locality of the mobile node’s movement, the mobile ...

Remotely sensed images are the main source for a variety of mapping and change detection applications. Images from different satellites are employed in several of these applications. However, each type of these images has different resolution and orientation. Hence, they need to be co-registered before any meaningful utilization. The first step in the registration process is to find conjugate p...

Automatic determination of three dimensional information from digital images is a fundamental problem in digital photogrammetry and computer vision. The hardest part of the problem is finding conjugate points in two images. Despite the wealth of information contained in digital images, factors such as occlusion and discontinuity weaken several matching algorithms. However, image matching using ...

Abstract The most important advantages of robotic welding are precision and productivity. Introducing visual systems in allows one to easily position the elements that welded. robot will then perform without error after recording points. application robotics is very because it enables autonomous work robot. Stereo vision used for three-dimensional reconstruction robot’s environment based on ima...
