DSR algorithm is applied to selects best path for communication between two nodes in a highly dynamic environment. As highly dynamic environment changes frequently, the probability of breakage of established path is high in such environment. Every time when established path breaks, a new route has to be discovered for communication between the nodes. In order to avoid path discovery every time,...

Algorithms for path planning have recently drawn renewed attention from researchers due to the advances of intelligent transportation applications. The difference on path planning between past and nowadays is the complexity of dynamic transportation network. This paper focuses on the road network modeling to speed up real time path discovery in dynamic and complex road networks. On the basis of...

a new dynamic friction model for modeling of elliptical vibration assisted turning (evat) was developed in this research. the periodic change of the friction force direction is known to be one of the most important causes of this phenomenon. in modeling of machining processes (including the evat process), static coulomb friction model was employed by most of the researchers. because of the peri...

Live-cell assays are used to study the dynamic functional cellular processes in High-Content Screening (HCA) of drug discovery processes or in computational biology experiments. The large amount of image data created during the screening requires automatic image-analysis procedures that can describe these dynamic processes. One class of tasks in this application is the tracking of cells. We des...

With conventional dynamic routing algorithms, many query messages are required in a distributed environment for efficient multicast routing of any traffic volume. We have developed a dynamic routing algorithm that uses a predetermined path search in which an appropriate multicast path is dynamically constructed by searching only a few nodes. This algorithm can construct an efficient multicast t...

Wireless sensor networks are composed of very small devices, called sensor nodes,for numerous applications in the environment. In adversarial environments, the securitybecomes a crucial issue in wireless sensor networks (WSNs). There are various securityservices in WSNs such as key management, authentication, and pairwise keyestablishment. Due to some limitations on sensor nodes, the previous k...

This paper presents a genetic-algorithm-based approach to the problem of UAV path planning in dynamic environments. Variable-length chromosomes and their genes have been used for encoding the problem. We model the vehicle path as a sequence of speed and heading transitions occurring at discrete times, and this model specifically contains the vehicle dynamic constraints in the generation of tria...

A new approach to constraint-based path selection for dynamic routing and wavelength allocation in optical networks based on Wavelength Division Multiplexing (WDM) has been proposed. The Distributed discovery wavelength path selection algorithm (DWP) proposed in the previous work takes a longer time for path selection even though it could solve some conflicting constraints imposed by electronic...

One of the major cipher symmetric algorithms is AES. Its main feature is to use S-BOX step, which is the only non-linear part of this standard possessing fixed structure. During the previous studies, it was shown that AES standard security was increased by changing the design concepts of S-BOX and production of dynamic S-BOX. In this paper, a change of AES standard security is studied by produc...
