Only immediate neighbor information. Uses the concept of ‘speed’ to achieve the soft Real-Time guarantee. Can co-exist with existing BE MAC. Uses feedback control and nondeterministic geographic forwarding.
The issues that concern Real-time communication between sensor networks has been presented.
A protocol called SPEED has been presented.
