DARP: dynamic and adaptive radio protocol for wireless sensor networks

The dynamic and adaptive radio protocol (DARP) is a new protocol proposal with some interesting features such as dynamic roles and the use of virtual sub-networks. The wireless sensor network state of art is discussed and some desirable features are presented in order to adapt these networks to new scenarios. These necessities are quite important to expand the applicability of wireless sensor networks and for this reason the DARP is proposed.
