The main characteristic ofthese networks is that of being functionally constrained due to a scarce availability ofresources and strong dependence on uncontrollable environmental factors. These con-ditions introduce severe restrictions on the applicability of classic real-time methodsaiming at guaranteeing time-bounded communications.Existing real-time solutions tend to apply concepts that were originally not conceivedfor sensor networks, idealizing realistic application scenarios and overlooking at impor-tant design limitations.
