Wireless sensor networks (WSNs) are large collectionsof resource limited nodes, densely deployed over alandscape. They gather and disseminate local data using multihopbroadcasting. WSN design and deployment is hampered bycurrently limited knowledge of the performance characteristicsof network nodes and protocols. Their systematic development,thus, requires a flexible simulation environment in which newmodels of specific node or network behaviours can be integratedeasily. This paper introduces a loosely coupled, object orientedsimulation environment for this task. The simulator is usedto investigate the efficiency of flooding protocols in WSNs. Fordense networks with noisy transmission, we show that using lowtransmission power maximises time and resource efficiency andthat the scalability of flooding for large networks is excellent.We demonstrate ways of improving flooding performance givenspecific deployment constraints.
