All automobile manufacturers continue to incorporate more and more technological features into their vehicles. One of the features is wireless access. A Vehicular Ad-Hoc Network or VANET is a technology that uses moving vehicles as nodes in a network to create a mobile network. VANET turns every participating vehicle into a wireless router or node. Some measurement studies have previously been ...

Deploying the internet and real time applications over next generation mobile networks indicates the need to pay attention to support mobility, mobile IPv6 (MIP6) is a protocol deal with mobility for next generation mobile networks. 4G/5G networks will probably transfer data and VOIP over IPV6 due to the massive amount of the IP addresses predicted to be used around the world. Providing high Qo...

WiMAX is the next generation technology that offers broadband wireless access over long distances. As WiMAX standards expand from considering a fixed line-of-sight propagation and point-to-multipoint infrastructure high frequency system to a lower frequency non-line-of-sight mobile system, WiMAX is open to more security threats than other wireless systems. This paper presents the different secu...

The high-speed mobile Internet has recently been expanded, many attractive services are provided. However, these services require some form of security-related technology. This paper outlines Japanese mobile services and exposits some mobile security topics including mobile spam, mobile malware, mobile DRM system, mobile WiMAX security, and mobile key management.

With the advent of the wide-spread use of smart phones, video streaming over mobile wireless networks has suddenly taken a huge surge in recent years. Considering its enormous potential, mobile WiMAX is emerging as a viable technology for mobile TV which is expected to become of key importance in the future of mobile industry. In this paper, a simulation performance study of Mobile TV over mobi...

although many researchers have written about WiMAX IEEE 802.16e Standard system, it needs more attention and analysis in next generation wireless networks. Multiple Input Multiple Output-Orthogonal Frequency Division Multiplexing (MIMO-OFDM) has become one of the key technologies for the B 3G & 4G broadband wireless communications. This paper is aimed at studying the performance analysis of OFD...

As mobile Internet environments are becoming widespread, how to revamp peer-to-peer (P2P) operations for mobile hosts is gaining more attention. In this paper, we carry out empirical measurement of BitTorrent users in a commercial WiMAX network. We investigate how handovers in WiMAX networks impact the BitTorrent performance, how BitTorrent peers perform from the aspects of connectivity, stabil...

The transmission performance for a downlink mobile WiMAX system with multiuser multiple-input multiple-output (MU-MIMO) systems in a computer simulation and field experiment is described. In computer simulation, a MU-MIMO transmission system can be realized by using the block diagonalization (BD) algorithm, and each user can receive signals without any signal interference from other users. The ...

WiMAX stands for Worldwide Interoperability for Microwave Access. In this paper, Performance evaluation of WiMAX and LTE (Long term Evolution) is done on network simulator NS version 2.34. Both are subjected to Real life scenarios to see how different factors viz. distance, number of subscriber stations, different modulation schemes and packet size affect the performances of WiMax and LTE. Simu...
