It begins with a description of basic concept of authentication process together with the essential factors required for use in authentication systems. This is followed by a description of the token types with an explanation of the threats and challenges founded in the authentication. Also included in this paper, an explanation of the fundamental cryptographic concepts that are used in this research study. A brief description of the suitable technology for use in the authentication system. Finally, the paper provides a review of literature that focuses on protection of the user against sensitive data theft (e.g. user credentials). However, some of the systems require modifications to the server, while some require additional hardware, to provide more protection to the system, besides making them difficult for adoption by the general public. This paper concludes with a comparison between the previous works regarding, password managers and some of their intrinsic characteristics which could be perceived as weaknesses and flaw. From this comparison, it can be concluded that there are limitations and shortcomings in all the existing approaches.

Transferring video in this type of network may suffer from many problems such as connection failures, weakness in the network layer, fading, network traffic overload, storage capacity, and so on. This study involves analyzing video transmission over heterogeneous using Network Simulation-NS2, the main errors which have occurred during video transferring, the types of video transmission techniques error correction methods, and various performance parameters such as the packet delivery ratio, throughput, normalized overhead control, and peak signal to noise ratio. The effect on the quality of the delivered video are calculated, and the results show that the quality of video transmitted over heterogeneous networks has improved using the proposed algorithm.

In this network type, the use of the clustering technique significantly reduces the routing traffic that occurs during the routing process. Clustering is used to divide an ad-hoc network into small sets of nodes, where each cluster consist of a cluster head, ordinary nodes and gateway nodes. Clustering can be used for the effective utilization of resources for large ad-hoc networks. This paper measures the impact of using clustering strategy in MANET and how this strategy can enhance the performance of this network, and resulted in increasing the calculated quality parameters, like throughput, packet delivery ratio, end-to-end delay and normalized control overhead. This study produced a simulation for Low-Energy Adaptive Clustering Hierarchy (LEACH) which is considered one of the clustering based routing protocols. A comparison is done between LEACH with the other types of routing protocols such as AODV, DSDV and OLSR which are considered non-clustering routing protocol. Conclusion and discussion of the simulation results have demonstrated the importance and effect of using clustering in MANETs.

There are different definitions for this term, ranging from any system that has sensors and actuators to a solitary interconnected network of physical items. This Paper shows that this term does not give enough information to construct a software architecture on. This is accomplished by taking an inside look at the IoT described in literature as well as the types of applications that exist on the market today and using the concept of software architectural styles to show how different areas in the IoT will need varying styles. This paper continued to classify solutions in the Internet of Things into different classes. The outcomes are that for a subset of the classes there is a reasonable style, however for remaining classes there are still different decisions where more context information is needed

One of the major challenges concerning the performance of mobile WiMAX is seamless handover. Research shows that a large portion of delay related to handover actually comes from user authentication and network entry and re-entry. In general, total delay associated with the handover process can be divided into three categories: i) link layer handover delay, ii) IP layer handover delay, and iii) security sub-layer handover delay. We propose a pre-authentication design that can provide seamless and safe connection when handover takes place. Our design is based on the least privilege principle; therefore, our approach guarantees backward/forward secrecy. We conduct research using an ns-2 simulation tool to measure the performance of our seamless handover. Our approach is validated using automated validation of Internet Security Protocols and Applications (AVISPA).

The next generation of broadband wireless networks including the IEEE802.16e standard, allow users to roam seamlessly and securely over the network. Unfortunately the current design suffers from lengthy delay between breaking of previous connection and making of next connection. This delay might not be tolerated by some of the real-time applications such as VoIP and video streaming. Therefore the need for fast and secure handover design becomes an urging necessity. This paper proposes a new handover mechanism enables fast and secure handover with minimum delay suitable for real-time applications. It should be pointed that this proposed handover protocol guarantees a forward and backward secrecy. We conducted our research using ns-2 simulation tool.
