New research by TSYS School of Computer Science associate professor Lixin Wang examines the impact of radio irregularities on network connectivity under a realistic shadowing model. Given that prior research showing that connectivity increases as radio waves becomes more irregular is based solely on simulation studies, or ignores the important boundary effect, it offers limited application for any practical wireless network. This is where Wang’s new study, which appears in a future issue of Ad Hoc & Sensor Wireless Networks, steps in, as it investigates the impact of radio irregularity on network connectivity with different transmission power settings, taking the important boundary effect into consideration. Wang’s shadowing model indicates that when each node transmits at a fixed uniform power, network connectivity increases as radio wave movement becomes more irregular. His shadowing model also indicates that when each node transmits at an adjustable power, so that the average node degree of the network is kept constant, the expected number of isolated nodes in the network is also unchanged. Thus, the results in Wang’s study may prove useful in designing guidelines for all practical multihop wireless networks in which both the shadowing and boundary effects must be taken into consideration.
The Turner College's new marketing intern Lizzy Grant , a senior marketing major from Newnan who previously attended Gordon State College, where she played varsity soccer, and is scheduled to graduate from the Turner College in May of 2024, has hit the ground running in her new position. She recently played a large role in the creation of a video tour of the Synovus Center, the main campus home of the Turner College. The video helps to guide new students on where to go in the building and who they can talk to if they help. The video showcases the Student Services Center, the main lobby, and more. The video is played as part of a loop on video screens placed throughout the Synovus Center. Lizzy's list of activities at CSU is impressive. She is the Treasurer of the Turner College's Marketing Club, the President of Marketing for the Turner College's chapter of the Financial Management Association, and an Ambassador for the Turner College. She is also the Treasurer of her s
