Our focus in this work is on analyzing the different
security levels that could be implemented in our system
while taking into account the energy consumption and performance
of different solutions. Currently, we identified a set
of possible technologies on different layers of the proposed
design (see Table I). As usual, a higher level of security
requires more CPU cycles, and hence increased cost and
latency, and a bigger packet size, which directly involves
a greater expenditure of energy, and could be critical on
mobile devices as this shortens the battery life of the devices.
