This chapter summarizes the major contributions of the book and highlights some future research directions and perspectives in the area of statistical properties of ad hoc network. Through this book, the temporal behaviour of a number of network parameters such as number of neighbour nodes, link load, path length and delay was characterized using time series models. It was found through simulated experiments that most of these parameters can be modelled with autoregressive models of order p, i.e. AR(p) for suitable values of p. The conducted experiments confirmed that the values of p lie between 1 and 3 for a threshold value of transmission range, sampling time and node velocity. Yet, above the threshold value, the autocorrelations of the node distribution are not very important. The book also discusses the threshold values of different parameters. These threshold values play a significant role while the ad hoc networks are practically deployed.
