Wireless Sensor Networks (WSN) are receiving growing attention in the research community. As simulation is a frequently used to test and validate the different approaches, the flexibility of the simulation environments to support the varied WSN schema is desirable. The multitude works regarding WSN in general [7, 8], and OMNeT++ [1, 2, 5, 6] in particular, confirm the rising interest in providing the simulation environment for WSNs. As map based design is most appropriate for WSN[3], unfortunately, no project within the WSN community investigates map paradigms for simulations. The map paradigm builds on the region principle and therefore, provides excellent modeling primitives for WSNs. Global maps are created for the sake of network monitoring [3, 10] or of event detection [3, 9]
