The total end to end delay for a message to travel L units away is also derived in [Effect of network parameters on delay in wireless adhoc networks] as given in equation  \begin*{equation} \begin{equation}  E[d_{t}]={Le^{-\Lambda\pi f^{2}}\over p \ast r}[e^{{\Lambda\pi f^{2}\over 1-{{\rm p}\lambda D\over 7}}}-1]  \end{equation}
