In the attempt to conquer all of these factors which affect the designs of Wireless sensor
networks, we have to trade off performance or expenses so that these liabilities are decreased to
tolerable levels. Due to the fact that such factors are motivated by cost and application l
performance and energy, to minimize their affects, it is preferable sometimes to acquire sensor
hardware that is more efficient in terms of security and consist of more than one base station.
This, of course, is more expensive than sensors having a si
protocols, software or certain services, sometimes there is a need for trading of performance or
cost for security.
