Megaxess

Chief Executive Officer

Did everything in Quality of Service products for Business ISPs and in 2000, the company valuation came at $180 million, but later became too difficult to sustain the valuation during telecom bust and in 2002, it was restructured by investors to become MXC and I am not part of MXC. Megaxess was an excellent technology company and I am a technologist and that's what I did. The company had great products.

Stevens Institute of Technology

Professor and Founding Director of US Navy Advanced Telecommunications Institute

Great research contributions that led to technology patents, publications and successful technology transfers. Developed the center for telecommunications research, introduced successful graduate programs in Computer and Information Engineering and Telecommunications Management. I had excellent students and graduate almost 28 doctoral students with Ph.D. and many many MS theses students.

Digital Compression Technology, LLC

Chief Technology Officer (Retired)

I am responsible for innovation and development of technologies employed in wired and wireless infrastructures.The CEO and I (CTO) have built the engineering team from a group of highly talented people in hardware design, software design, system design. The first hardware product has been tested and the engineering team has completed the product specification. The first product is expected to provide full duplex high-speed telephone wired solution for multimedia applications from home to Central Office using the existing infrastructure. DcT is considering external manufacturing and marketing, and deployment of the product. Several companies have been evaluated and the final selection has been done. The product is expected to be ready for deployment in early 2018.

Prairie View A&M University

Texas A&M University System Regents Professor and TI Endowed Chair Professor (Retired)

As the director of ARO Battlefield Communications (CeBCom) Research, I have established research in many architectural issues in wireless networks, multi-service applications and network management. Many doctoral students have been cranking a lot of research these days.

Dynamic Position Location and Tracking (D-PL&T) using Location based Hash Scheme for Malicious Detection under Doppler Spread Rayleigh Channel

WSEAS Journal (Transaction) in Communications,E-ISSN: 2224-2864,Issue 7, Volume 12, July 2013

A novel approach of the integrated security and dynamic Position Location and Tracking (PL&T) for malicious node maintaining two friendly nodes is proposed. Location based hash security scheme is deployed for detection of friendly and malicious nodes by encrypting hash functions using private location assets to increase the security level. In addition, PL&T is deployed forming the robust tracking zone and triangulation using two friendly nodes equipped with steered Directional antenna in Mobile Ad hoc Networks. The integrated “zone finding” and “triangulation” with adaptive beam forming allow the system to use only two references by switching nodes in and out of range. Pre-zone finding of a node permits proper geometry to be established for triangulation. This provides significantly improved tracking accuracy as compared to the triangulation only using three references. Also, narrow zone reduces beam width, thus significantly decreasing the tracking error but increases the zonal overhead. The PL&T performance analysis shows that by deploying interleaving Koay-Vaman (KV) transform coding technique for forward error correction and sample interleaving will achieves greater tracking accuracy using lower Eb/No in fast Doppler spread Rayleigh channel. The average estimated location tacking error and average zonal overhead are significantly decreased under fast Doppler spread fading channel than slow Doppler spread fading channel.

“Analyzing the Performance of the Dynamic Position Location and Tracking of Mobile Nodes Using Omni Directional Antenna in MANET”

International Journal of Wireless Mobile Networks (IWJMN), Vol. 7, No. 4, July 2015.

The performance of dynamic Position, Location and Tracking of mobile nodes is achieved by a two step integrated process involving zone finding followed by triangulation. In this paper, the performance of the integrated algorithm has been shown to be extremely accurate (less than a foot accuracy) for a scalable Mobile Ad Hoc Network (MANET) where each radio uses an omni-directional antenna. The processing time of the algorithm is very fast to enable its use for both slow speed movement as well as high speed movement.
