Minimization of the Diffusion Delay of a Tree-Based Wireless Sensor Network

In wireless sensor networks, saving energy is crucial in order to increase the network lifetime. Energy is often saved by synchronizing the nodes activity, and having long periods of inactivity, or by having nodes exchange a global activity schedule. The synchronization and the exchange of a global schedule are two examples where an information is broadcasted from a specific node to the whole network. In this paper, the authors focus on the delay required to broadcast an information in the whole network using a tree topology.
