Generally, wireless sensors networks and particularly those used in embarked computing, have answered with drastic temporal pressures. The optimization of the methods of access to the medium is the only ways which push's or set for bringing solution. Within effect, the technology IEEE 802.15.4 reposes on functionalities orientated to toward that problematic issue. However, a big number of holes unfortunately interfere and interrupt with that technology. A work of identification and resolution of these holes make the object of this paper.
