Abstract: Taking into consideration, the situations and the security policies of organization, we have decided to implement the hybrid Application Layer Firewall (Proxy Server).we need for firewall and network security is very important with a rapid expansion of the Internet, and more and more use of computer networks throughout the world. Firewalls protect the computer systems connected to the private network or local network against attacks from the Internet. Firewalls are considered to be one of the best and most reliable means of network protection against intruders. Most of the today's firewalls are categorized as router-based, circuit-level, and application level. The goal of this project is to implement the application firewall as the application firewalls provides more security flexibility, scalability and maintainability, which is favorable for corporate security environment. We have decided...........

Abstract: International competition of agricultural products is increasing fierce with the deepening of economic globalization .This rises the need for an automatic food understanding from images which is an interesting challenge for computer vision experts. In this project, we address the study of fruit and pulses image processing from the perspective of computer vision. The proposed local smart grid motif XoR pattern (LSMXoRP) exploits the relation between center pixel with its neighbors using 1×3 grid structure to extract local information structure. Further, it considers relation among neighboring pixels by using a clockwise scan unlike LBP which exploits the relation between center pixel and neighbor pixels only for better feature extraction. The experimental results indicate that performance of proposed LSMXoRP surpasses the existing LBP and LTP methods in terms of recognition rate..

Abstract: The Internet of things is a new concept in the world of technology and communications, where each entity has the ability to send data through communication networks. The modern world of telecommunications technology has shown that in the business world, those who have access to more data and information will control the future. The Internet technology of objects has also been developed due to the same concept.Considering the ever-increasing number of sensors and smart appliances and their connection to the Internet, wewill need standard protocols for the Web that are suitable for limited devices with Internet connectivity. In this regard, it is felt more and more necessary to use a practical and lightweight protocol because of the limitations of the above. The main objective of this article is to evaluate the IOT protocols to provide an efficient protocol for using in constrained nodes.

Keywords: IOT, M2M, HTTP, CoAP
