On the expected moments between two identical random processes with application to sensor network

Abstract: We give a closed analytical formula for expected distance to the power $a$ between two identical general random processes, when $a$ is an even positive number. As an application to sensor network we prove that the optimal transportation cost to the power $b>0$ of the maximal random bicolored matching with edges ${X_k,Y_k}$ is in $\frac{\Theta\left(n^{\frac{b}{2}+1}\right)}{{\lambda}^b}$ when $b \ge 2,$ and in $\frac{O\left(n^{\frac{b}{2}+1}\right)}{{\lambda}^b}$ when $0< b < 2.$
