THE STRATEGY
Primary Goal:
To become a nationally recognized
research group in wireless
communications and networking by
capitalizing on the existing strengths

Ongoing and Planned Activities
• Recruit a senior faculty member (Ying Wu Endowed Chair Position) to
•
•
•
•
•
•
fulfill leadership in wireless networking to mirror and enhance the
sustained success and high visibility of the communications and signal
processing group
Search for junior faculty member
Initiate and pursue research in the field of wireless communications and
networking in an expanding, cross-layer manner, increase output
volume of publications
Increase research support from federal, industrial, military agencies
Teach graduate courses in the fields of wireless communications and
networking, propose and plan new courses, short courses, seminars
Undertake initiatives to recruit highly qualified graduate students,
research associates and visiting faculty members
Organize and run seminars, workshops, symposia

IMMEDIATE IMPACT
• Wireless Communications and Networking draws
•
from the collective strengths of two areas in ECE:
– Communications and Signal Processing and
– Computer Networking
– the two areas are overlapping
We have carefully evaluated our strengths and areas
of need
– We have identified the need for leadership in wireless
–
networking, in order to synergize individual efforts
In order to address this need, we have formed a search and
recruitment committee (chaired by Professor Bar-Ness)
comprising of members of both areas
