| Abstract | Networking of computing devices has been continuing to be an ever expanding area of importance in recent years. Different technologies, protocols, services and usage patterns have contributed to the major research interests in this area of computer science. This special issue is an effort to bring forward some of these interesting developments that are currently being pursued by researchers in different parts of the globe. Our objective is to provide the readership with the latest and novel in computer networking through this.This Special Issue presents selected papers from the IEEE International Conference on Computer and Information Technology (ICCIT 2008) held on December 25-27, 2008 at Khulna University of Engineering and Technology, Bangladesh. ICCIT 2008 was the eleventh annual conference in the series, the first one was held in Dhaka, Bangladesh, in 1998. Since then the conference has grown to one of the largest conferences in the South Asian region, focusing on computer technologies, IT and relevant areas, with participation of academics and researchers from many countries. A double blind review process is followed whereby each paper submitted to the conference is reviewed by at least two independent reviewers of high international standing. The acceptance rate of papers in recent years has been less than 30%, indicative of the quality of work the papers need to demonstrate to be accepted for presentation at the conference. The proceedings of ICCIT 2008 were included in IEEExplore. In 2008, a total of 538 full papers were submitted to the conference of which 138 were accepted for the conference after reviews conducted by an international program committee comprising 77 members from 12 countries with assistance from 83 reviewers. Among those 138, 33 papers were dealt with topics in the networking area. From those 11 highly ranked papers were invited for this Special Issue. The authors were invited to enhance their papers significantly and submit the same for review. Of those, six papers survived the review process and have been selected for inclusion in this Special Issue. The authors of these papers represent academic and/or research institutions from Bangladesh, Iran, Japan, and Sweden. The first paper titled "A Fuzzy Logic-Based Adaptive Handoff Management Protocol for Next-Generation Wireless Systems" deals with the issue of seamless handoff in next-generation wireless networks. The authors propose a fuzzy logic based adaptive handoff protocol that when combined with an existing cross-layer handoff mechanism, yields better performance than existing solutions. Next, the manuscript " Dynamic Communication Performance of the TESH Network under Nonuniform Traffic Patterns" deals with performance issues of Tori-connected mESH network. The authors focus on the conditions and proof for TESH networks to be deadlock free and through simulations, show that the dynamic communication performance of TESH network is better than mesh and torus networks.Author of the third paper titled, "Distributed Control Routing Algorithms for Rearrangeably Nonblocking Optical Banyan Networks", deals with a special type of optical banyan networks called Vertically Stacked Optical Banyan networks. The author shows that it is practically impossible to implement N-completely connected processors to take routing decisions for large values of N. The author therefore considers loosely connected processors scenario and has proposed two algorithms that are significantly fast. The fourth paper "Performance Evaluation of Different QoS Models for Connecting Telephone Exchange Centers over Metro Ethernet Networks" studies the performance of connecting telephone exchange centers over a metro Ethernet network using MPLS and DiffServ QoS model. The authors evaluate the system through simulation of various scenarios. Next, in the article "An Analysis of the Robustness and Stability of the Network Stack in Symbian-based Smartphones", the authors describe research outcome on security issues of Symbian OS based smart phones. Interestingly enough, the authors have reported a couple of cases where their systematic attacks on the phones have driven the phone sets non-functional. This would be a useful read for the end-user as well as OS developers for the smart phones.Optimal resource allocation is important in ensuring appropriate quality of service to devices and applications. Due to limited bandwidth, this becomes an even bigger concern over wireless networks. The final manuscript "Prediction of State of Wireless Network Using Markov and Hidden Markov Model" proposes mechanisms using Markov Model and hidden Markov Model to predict the number of devices connected to a specific AP at a given instance of time.Finally, we express our sincerest gratitude to both George J. Sun, the founding editor of the journal, and Niki Pissinou, the editor-in-chief, for this opportunity and our colleagues in the discipline who have kindly volunteered in the review process of this special issue. Without timely contributions by the reviewers, this initiative would not have been realizable. |
