Power-aware Routing Protocols
Energy required to transmit a signal is approximately proportional to d, where d is the distance and is the attenuation factor or path loss exponent, which depends on the transmission medium. When (which is the optimal case), transmitting a signal half the distance requires one fourth of the energy and if there is a node in the middle willing to spend another fourth of its energy for the second half, data would be transmitted for half of the energy than through a direct transmission – a fact that follows directly from the inverse square law of physics.
The main disadvantages of such algorithms are:
- This method induces a delay for each transmission.
- No relevance for energy network powered transmission operated via sufficient repeater infrastructure.
