1. A method for transmitting sensed data in a wireless sensor network including multiple sensors and a database, the method comprising:
- automatically dividing the multiple sensors into sensor groups, each of the sensor groups including at least one sensor;
determining a lead sensor in each of the sensor groups;
encrypting the sensed data to generate encrypted data in ones of the multiple sensors excluding the determined lead sensors; and
transmitting the encrypted data.
