One danger with this approach is that the very protection from DdoS attacks can
drain the battery, thus accomplishing the goal of the attacks themselves as constant
checks for message authencity extract a high energy toll from the batteries.

Conclusion
Sensor networks have come a long way from obscure military beginnings into a widely
discussed important research subject, and in the twenty-first century first everyday
applications are slowly emerging. Since sensor nodes are in concept small computers
with high interconnection ability, a lot of solutions developed for traditional com-
puters (such as routing, time synchronization, and security) could be reused, but
with substantial adaptations due to significantly smaller processing power and
memory sizes smaller by several orders of magnitude. On the other hand, some
other concepts, such as positioning and localization, were never necessary in traditional
computers and thus had to be developed from scratch.
