Exploring performance upper bound of wireless sensor networks(WSNs)is very important for understanding the worst-case behavior of the network
and may provide proper design reference.Based on this
a tree WSNs modeling and network
methodology of analysis on performance upper bound is proposed.This method confirm model through depth
the maximum number of child routing node and the maximum number of child end nodes of tree topology.Using network calculus knowledge
recurrence expressions for node buffering upper bound and node bandwidth requirements as well as end-to-end data flow delay upper bounds as a function of topology structure and transmission specifications are derived
how to apply the derived expression to IEEE 802.15.4/Zig Bee tree WSNs is demonstrated.
