Capacity of MIMO mobile wireless ad hoc networks


We compute the capacity of wireless ad hoc networks when all the nodes in the network are endowed with $M$ antennas. The derivation is based on a new communication scheme for wireless ad hoc networks utilizing the concept of cooperative many-to-many communications, as opposed to the traditional approach that emphasizes on one-to-one communications. We show that the upper bound average asymptotic capacity of each cell is (2pi P_t M C_{cell} [1-exp(-frac{C_{cell}}{ heta})] ), for network parameters $C_{cell}geq 1$, $0 < heta < 1$, and transmit power $P_t$.
