EDITORIAL PREFACE
Debashis Saha, Editor-in-Chief, IJBDCN Varadharajan Sridhar, Editor-in-Chief, IJBDCN
This issue of IJBDCN commences the first anniversary of the editors taking over the editorial mantle from Jairo Guitterez, who continues to provide valuable guidance. This issue of IJBDCN addresses the gap between theory and on-field implementations of network design and performance analysis, as well as covers the design and performance analysis of wireless networks. In addition, this issue includes the book review of Networked Communities: Strategies for Digital Collaboration authored by Albert, Flournoy, and LeBrasseur.

PAPER ONE
A Survey on Classical Teletraffic Models and Network Planning Issues for Cellular Telephony
Francisco Barcelo-Arroyo, Universitat Politècnica de Catalunya, Spain Israel Martin-Escalona, Universitat Politècnica de Catalunya, Spain
Research on traffic characterization and analysis of cellular networks has been very active in the past decades; however, it is difficult for network planners to incorporate new results to network engineering. On the one hand, some models are very complex and need advanced programming and skills to be properly computed. On the other hand, reliability on those models is poor because there is a general lack of published field studies to corroborate them. This article proposes simple well-known teletraffic models for cellular networks compared to the conventional Erlang-B frequently applied when a first estimate is needed. The authors review the latest results on the characterization of the arrival process and service time in cellular systems. According to the arrival and service characteristics, this article proposes three models to obtain an approach to the performance characteristics of the cellular system.

PAPER TWO
Testbed Implementation of a Pollution Monitoring System Using Wireless Sensor Network for the Protection of Public Spaces
Siuli Roy, Indian Institute of Management Calcutta, India Anurag D, Indian Institute of Management Calcutta, India Somprakash Bandyopadhyay, Indian Institute of Management Calcutta, India
Air pollution is an important environmental issue that has a direct effect on human health and ecological balance. Factories, power plants, vehicles, windblown dust, and wildfires are some of the contributors of to pollution. Reasonable simulation tools exist for evaluating large scale sensor networks; however, they fail to capture significant details of node operation or practical aspects of wireless communication. Real life testbeds, capture the realism and bring out important aspects for further research. In this article, the authors present an implementation of a wireless sensor network testbed for automatic and real-time monitoring of environmental pollution for the protection of public spaces. The authors describe the physical setup, the sensor node hardware, and software architecture for �anytime, anywhere� monitoring and management of pollution data through a single, Web-based graphical user interface. The article also provides practical issues in the integration of sensors, actual power consumption rates and develops a practical hierarchical routing methodology.

PAPER THREE
A GPS Based Deterministic Channel Allocation for Cellular Network in Mobile Computing
Lutfi Mohammed Omer Khanbary, Aden University, Yemen Deo Prakash Vidyarthi, Jawaharlal Nehru University, New Delhi, India
The scarcity of the radio channel is the main bottleneck toward maintaining the quality of service (QoS) in a mobile cellular network. As channel allocation schemes become more complex and computationally demanding, alternative computational models that include knowledge-based algorithms and provide the means for faster processing are becoming a topic of research interest. The authors introduce an efficient deterministic technique, capable of handling channel allocation problems as an alternative. The proposed model utilizes the global positioning system (GPS) data for tracing the hosts� likely movements within and across the cells and allocates the channels to the mobile devices accordingly. This article evaluates the performance of the proposed technique by conducting simulation experiments for the two parameters�call blocking and handoff failures. In addition, the authors carry out a comparison of the proposed model with an earlier model to estimate the effectiveness of the proposed technique.

PAPER FOUR
Energy-Efficient Self-Organizing Routing for Wireless Mobile Networks
Melody Moh, San Jose State University, USA Rashmi Kukanur, San Jose State University, USA Xuquan Lin, San Jose State University, USA Subhankar Dhar, San Jose State University, USA
The instant deployment without relying on an existing infrastructure makes mobile ad hoc networks (MANET) a striking choice for many dynamic situations. An efficient MANET protocol may be applied to other important emerging wireless technologies, such as wireless mesh and sensor networks. In this article, the authors propose a hierarchical routing scheme that is scalable, energy efficient, and self-organizing. The new algorithm that is discussed the dynamic leader set generation (DLSG), which dynamically selects leader nodes based on traffic demand, locality, and residual energy levels, and de-selects them based on residual energy. Therefore, energy consumption and traffic load are balanced throughout the network, and the network reorganizes itself around the dynamically selected leader nodes. This article analyzes time, space, and message complexities and addresses implementation issues. In addition, the authors carry out a performance evaluation by simulating DLSG and four existing hierarchical routing algorithms.
