We propose the implementation of a wireless sensor network applied to automation control applications, when the guarantee of a delay delivery for the complete reception of messages is necessary. The 802.15.4 wireless standard network offers possibilities of management of the bandwidth. This paper presents the method to guarantee the deadline transmission of periodic messages. For external messages (crossing the network from clusters to its destination), this average latency is used as a parameter of the routing protocol decision balance between energy saving and delay transmission. In this last case, a QoS method all over the network has to be installed to maintain a bounded end to end delay transmission. This work is still in progress. A specific Matlab simulator has been developed, principles of this routing method are mentioned at the end of this paper
