Table 5: Deployments: used motes and radio chips. Mica2 [64] and MicaZ [3] platforms were very popular in early deployments. TelosB-compatible platforms (TMote Sky and others) [2, 65] have been the most popular in recent years. _Design rule 8_: TelosB platform support is essential. MicaZ support is optional, yet suggested, as sensor network research laboratories might use previously obtained MicaZ motes, especially for student projects. Almost half of deployments (47%) use adapted versions of off-the-shelf motes by adding customized sensors, actuators and packaging (Figure 5). Almost one third (32%) use custom motes, by combining different microchips. Often, these platforms are either compatible or similar to commercial platforms (for example, TelosB) and use the same microcontrollers (MCUs) and radio chips. Only 20% use motes off-the-shelf with default sensor modules. _Design rule 9_: The WSN OS must support implementation of additional sensor drivers for existing commercial motes  
_Design rule 10_: Development of completely new platforms must be simple enough, and highly reusable code should be contained in the OS
