    The main purpose of this workshop is to promote further research interests and activities on scenario modelling of wireless networks. It is also aimed at increasing the synergy between academic and industrial researchers working in this area. We are interested in experimental, systems-related, theoretical, and work-in-progress papers in all aspects of wireless network scenarios.

    • Model complexity vs. better parameter value estimation: comparing four topography-independent radio models

      Research Article in 1st International ICST Workshop on Scenarios for Network Evaluation Studies

An evolutionary optimization process was ap- plied to fnd near optimal parameter values four these mod- els. We describe the optimization process, the error function that guides it and discuss the results.

    • A mobility model for pedestrian content distribution

Such a scheme, where the data is carried by people walking around and relayed from device to device by means of short range radio, could potentially form a public content distribution system that spans vast urban areas. The transport mechanism is the flow of people and it can be studied but not engineered. The question addressed in this paper is how well pedestrian content distribution may work. We answer this question by modeling the mobility of people moving around in a city, constrained by a given topology. Our contributions are both the queuing analytic model that captures the flow of people and the results on the feasibility of pedestrian content distribution. Furthermore, we discuss possible extensions to the mobility model to capture speed-distance relations that emerge in dense crowds.

The performance of many of these protocols is highly sensitive to the underlying mobility model which determines the nodes' movements, and the characteristics of these mobility models are not often studied or compared. With few exceptions, authors test their ideas using mobility models implemented on simulators written for the specific purpose of testing their protocols. We argue that it is better to unify these simulations to one highly capable simulator. We develop a suite of mobility models in OMNeT++ that specifically target delay tolerant networks. We also present a series of metrics that can be used to reason about mobility models independent of which communication protocols and data traffic patterns are in use. These metrics can be used to compare existing mobility models with future ones and also to provide insight into which characteristics of the mobility models affect which aspects of protocol performance. We implement a tool that derives these metrics from OMNeT++ simulations and implement several popular delay tolerant mobility models. Finally, we present the results of our analysis.
