Special Issue on Modelling and Simulation of Wireless and Mobile Systems Wireless and mobile networking technology has undergone dramatic changes in the past two decade, moving from a technology that barely supports low bandwidth analogue voice communication services, to several technologies that enable a plethora of untethered high bandwidth rich multimedia communication services with or without mobility. In this short laps of time, no less than four generations of standards for mobile cellular networks, and a large number of standards for metropolitan, local, and personal area networks have seen the light. In this same laps of time wireless local area networking has gone from supporting merely 1 Mbps in its ancestor (WaveLAN), to providing many users with thousands of megabits per second in the forthcoming IEEE802.11ac standard. These standards and technologies encompass many aspects of communication, including, the presence or lack of infrastructure, the mobility characteristics of the users, the bandwidth provided by the network, and all the techniques involved to facilitate these aspects. Engineering such networks, defining the underlying communication principles that enable them, and imagining the multitude of applications that fuel them, have been driving research at a very fast pace; and a fundamental aspect of all such research activities is our ability to model, simulate and analyse the performance of such mobile and wireless systems. It is our pleasure to guest-edit this special issue, designed to give an overview of some advances in modelling and simulation of wireless and mobile networks. The issue is organized around nine articles that encompass several aspects of wireless and mobile networks. Several of these articles are rewritten and extended versions of the best papers that were presented at the 13th ACM International Conference on Modelling, Analysis, and Simulation of Wireless and Mobile Systems. Each paper in this issue has undergone several additional new rounds of peer-reviewing, revisions, editing and shepherding to reach its current form. The papers in this issue can be classified along several aspects related to the subject of the issue. The first aspect concerns the technology/type of network under consideration. In this broad classification, we have several categories, including Wireless LAN, Sensor networks, hybrid 3G/WiFi networks, Optical ad hoc networks, wireless mesh networks and cognitive radio networks, with the lion’s 1570-8705/$ - see front matter Ó 2013 Published by Elsevier B.V. http://dx.doi.org/10.1016/j.adhoc.2013.10.003
share going to the first two categories. From the perspective of the domain of application, several aspects are covered, ranging from modelling realistic physical layer aspects, to modelling MAC layer aspects, to studying the performance of new applications that leverage wireless communications to enhance the services provided to the network users. Despite the amount of work that has been done in the area of sensor networks, this area remains active because of the multitude of possibilities it offers, Indeed sensor networks are often application driven and, solutions and performance observed in one application of sensor networks may not apply to another one. In this category we have three papers. The first one by H. Li et al., focuses on studying the performance of data aggregation in sensor networks as a means to reducing latency while adopting realistic interference model for physical transmissions. The second paper by L.A. Villas et al., investigates the efficiency of data collection in sensor networks by adopting spatial correlations awareness to reduce redundancy of data. The third focuses on developing a performance model for QoS enable MAC protocol for sensor networks. In addition to these articles focused mainly on the technological aspects of sensor networking, we also have one paper by K.L. Huang that addresses the application aspects of sensing in 3G/WiFi networks and advocates the need for reputation systems in order to validate data collected from the huge number of smart phones that could be tapped as a large network of distributed mobile sensing nodes. In the area of wireless local area networks, two papers are selected. The first one authored by D. Milioris et al., covers the use of signal-strength fingerprinting as a means to determine more accurately the location of mobile users in a wireless local area network. While the second authored by K.-L. Hung et al., proposes to improve the performance of extended wireless local area networks with hidden terminal via the joint design of and association control, rate control and contention resolution algorithm. The remaining three papers, cover three different other equally interesting and important aspects wireless networks. The first one by M. Bilgi et al., concentrates on the study of the capacity that can be achieved in an ad hoc network that uses optical communications in the

presence of mobility. The second paper by S. Bayhan et al., studies the performance of channel selection in cognitive radio networks by modelling the channel selection (bestfit algorithm) using a Markovian approach. Finally the last paper authored by S. Ulug et al. focuses on the perforamcne of supporting IPTV service distribution over wireless mesh operation mode of WiMAX networks. It has been our pleasure to put together this special issue to give a small glimpse on some current research in wireless and mobile systems and their performance. Last but not least, we thank the authors for their submissions, and the anonymous referees for their reports that were useful to the authors and the guest editors.
