I am writing to express my interest in applying for vacant PhD position in the physical layer communication project at your department.

Based in Tehran, I graduated from Master in telecommunication engineering at K. N. Tousi
University of Technology (KNTU), Tehran, Iran . I am currently employed as a research manager
at Acom Ertebat Rain Ltd. and I have 17 years of full-time work experience.
On the first phase of my technical activity, I was engaged in programming, design and
implementation of the first 4 layers in ITUT protocols, namely ISDN and signaling system no.7
protocol stack, which has a good conceptual resemblance with OSI model. In the course of this
phase, I had to engage myself with real-time operating systems in order to design and
implement an embedded communication subsystem. This led me to the design of a proprietary
OS and then had to converge it with a Linux RTOS.

In the second phase of my technical activity, there was the interconnection of VoIP network to
the above TDM communication subsystem. This brought me a lot of experience in TCP/IP
protocols suite for transportation of different signaling messages between TDM switch and VoIP
network (and NGN protocol stack such as SIGTRAN, MTPUA,MEGACO, MGCP, RTP, SIP.. .).
At this point I had to manage these two different networks by an integrated management
system. So I was appointed to investigate the design of a network management system
according to FCAPS model and research about different protocols for FCAPS implementation
such as SNMP-Vx, Netflow, Netconf, Syslog, ...

In the third phase of my activity, I had to work out the feasibility of a TETRA network
management system, which was fully based on IP. Here I used my vast experience from previous
tasks, deploying protocols such as ARP, RARP, IP, PPP, ICMP, DHCP, UDP, TCP, Http and
especially the different IP routing protocols for the LANs, Enterprise network and Wan.
As in the course of my professional life, I have always been active in the edge technologies, I
would very much like to use my experience for the development of new technologies  in the context of a PhD educational course.

Attached are my contact details and detailed CV for your review. I would appreciate the
opportunity to promote my status through any questions raised in due course. Thank you very
much for your consideration.
Sincerely yours,
Seyed Alireza Omranian
Tehran-Iran
