OMNET++ is a simulation of wireless sensor networks. The document discusses sensor node characteristics such as being low cost, low power, and small in size with different communication distances. It also discusses that sensor node lifetime depends highly on battery lifetime, and the main energy drains come from sensing, computation, and communication functions.

4. Sensor Node Characteristics
 Low cost
 Low power
 Small size
 Different communication distances

5. Energy Consumption in Wireless Sensor Network:
 The life time of the sensor node is highly dependent on the battery life
time. Alternatively there are times when it is possible to use a power
source close by to power the node; but this is not always possible.
 The main power drain is through the three important operations which
are sensing, computation and communication.
