Wireless Sensor Network deployment using DEVS formalism and GIS representation

Wireless Sensor Network (WSN) deployment appears like a crucial step for network Quality of Service (QoS). In this context a real conception has to be planed before a deployment on the studied area. Actually researches use a simple and regular Area of Deployment (AoD) representation and do not allow interactive interface for a non programmer. Our approach tries to provide a tool to elaborate a strategy of WSN deployment. In a first part we show how it is possible to have an easy representation of WSN deployment components by using Discrete EVent Specification (DEVS) formalism. In second part we present an application that allows an accurate representation of WSN deployment based on Geographic Information System (GIS) from the results of the DEVS application. We present an example of WSN deployment that takes into account elevation variation on a mountainous area.
