New Design Themes
	n Long-lived systems that can be untethered and unattended – Low-duty cycle operation with bounded latency – Exploit redundancy  and heterogeneous tiered systems n Leverage data processing inside the network – Thousands or millions of operations per second can be done using energy of sending a bit over 10 or 100 meters – Exploit computation near data to reduce communication n Self configuring systems that can be deployed ad hoc – Un-modeled physical world dynamics makes systems appear ad hoc – Measure and adapt to unpredictable environment – Exploit spatial diversity and density of sensor/actuator nodes n Achieve desired global behavior with adaptive localized algorithms – Can’t afford to extract dynamic state information needed for centralized control
