IEEE Transactions on Mobile Computing (TMC) continues to grow in both quality and quantity of submissions received per year. The larger number of papers has resulted in a longer backlog, and a consequent increase in the delay in publication of accepted papers. To address this issue, TMC has begun monthly publication since January 2006. Also, while the review process for TMC remains quite timely, we are in the process of increasing the number of associate editors on the editorial board, which is expected to further reduce the time required to complete the review process. Aside from increasing the number of associate editors, an attempt is being made to increase the diversity of expertise available on the editorial board. As a result of this process, I am pleased to introduce 10 new associate editors: Aura Ganz, Robert S.H. Istepanian, Srikanth V. Krishnamurthy, Marwan Krunz, T.V. Lakshman, Rohit Negi, Rajeev Shorey, Gaurav S. Sukhatme, András Valkó, and Yongguang Zhang. Collectively, these editors represent expertise in various aspects of mobile computing and wireless networking, as well as applications of these technologies in domains such as medicine and robotics. Please find below the biographies of the new associate editors. I look forward to continue working with the editorial board, the authors, the referees, and the readers to continue to improve the quality and timeliness of TMC. If you have any suggestions in this regard, please feel free to contact me, or any member of the editorial board.
