Abstract: This paper studies capacity estimation for Mobile Ad Hoc Networks(MANETs) by using directional antennas. A matrix-based channel-shared fast estimation algorithm is proposed to calculate the network capacity in a network scenario in which there is channel shared among multiple sessions and there is end-to-end delay constraint between each source and destination pair. The algorithm calculates the network capacity in terms of the maximum number of one-hop paths based on the adjacency matrix of the network. Numerical and simulation results show that the algorithm can estimate the network capacity much faster than Brute-force search algorithm with the same accuracy.
