Tool-supported requirements-based topology design for wireless sensor networks

Planing the topology of wireless sensor networks (WSN) for a specific application is a complex task. Each application defines requirements to its WSN. Some of these requirements have to been fulfilled by the wireless technology, e.g., energy consumption and throughput, and some by the network topology, e.g., redundancy and latency. Topology makes restrictions to the wireless technology and the wireless technology makes restrictions to the network topology. In this paper we present an algorithm to select a network topology and a wireless technology depending on application's requirements automatically. The algorithm is part of the Sens4U approach, which aims to simplify and possibly automate the process of building WSN applications and support applications development done by nonWSN-experts.
