WSNs are distributed sensing tools with monitoring capabilities unavailable until now. Network elements (sensor nodes) are frequently pointed out as a new computer systems class due to its ubiquitous an analytical features. Wireless Sensor Networks have evolved quickly in recent years. Such evolution lead to specializations such as Wireless Visual Sensor Networks and Multi-tier, Multimodal Wireless Sensor Networks (M2 WSN). The desing, modeling and implementation development of a WSN M2 for environment monitoring is treated in this work. Simulations with such network shows that they present better usage of components and energy resources with little sacrifice to the application performance.
