Abstract

The PDP(Partial Dominant Pruning) method is known as most practical method to reduce overlapped broadcasting messages by designating forward node as in-fly type when broadcasting occurs in the mobile wireless network with directional antenna. In this paper, we introduce DPDP(Directional PDP) that reduces not only number of nodes but number of used antenna elements simultaneously. By simulation, we proved our algorithm reduces number of forwarding nodes per antenna element and number of overlapped messages that each node receives compare to PDP though the number of antenna elements are increasing rather than in case of using omnidirectional antennas.
