The upper bounds on lifetime of three dimensional extended Time hopping impulse radio Ultra- wide band (TH-IR UWB) sensor networks are derived us- ing percolation theory arguments. The TH-IR UWB sen- sor network consists of n sensor nodes distributed in a cube of edge length n1=3 according to a Poisson point process of unit intensity. It is shown that for such a static three dimensional extended TH-IR UWB sensor network, the upper bound on the lifetime is of order O(n¡1), while in the ideal case, the upper bound on the lifetime is longer than that of a static network by a factor of n2=3. There- fore sensor nodes moving randomly in the deployment area can improve the upper bound on network lifetime. The re- sults also reveal that the upper bounds on network lifetime decrease with the number of nodes n, thus extended TH- IR UWB sensor networks aren't prone to be employed in large-scale network.
