Abstract:

In this paper, we study capacity estimation for mobile ad hoc networks (MANETs) using directional antennas. A matrix-based channel-sharing fast calculation algorithm (MCFCA) is proposed to estimate the network capacity in a network scenario in which there is channel sharing among multiple sessions and traffic is delay sensitive with an end-to-end delay constraint. The new algorithm estimates the network capacity in terms of the maximum number of one-hop paths based on the adjacency matrix of the network. Through numerical results, we show that our proposed algorithm can calculate network capacity much faster than the well-known Brute-Force Search Algorithm (BFSA) but with the same accuracy.
