摘要：Broadcasting is the simplest way to send a message from one node to all the other nodes in a network. Simple flooding is the simplest form of broadcasting that provides important control, route discovery, and network information update functionality for unicast and multicast protocols. However, simple flooding generates too many broadcast message duplications in networks. The Minimizing Re-Transmissions (MRT) approach has been developed to reduce broadcast duplication in ad hoc wireless networks by minimizing the number of retransmitting nodes based on the network topology information. While MRT is one of the most efficient broadcasting techniques for ad hoc wireless networks, when MRT is applied for wired networks, it still generates broadcast duplication in the networks. In this paper, we develop a variant of MRT for wired networks called MRT for wired networks (wMRT) to completely remove broadcast duplication in wired networks. In addition to minimizing the number of retransmitting nodes, wMRT also minimizes the number of retransmitting ports of each node in wired networks. This results in no broadcast duplication in wired networks. The traffic performance of wMRT is analyzed, evaluated, and compared to that of the simple flooding and MRT techniques. Simulations are conducted using the OMNeT++ simulation tool in order to validate the traffic performance analysis. The analyzed and simulated results show that the wMRT completely removes broadcast duplication in wired networks, thus saving a significant amount of network bandwidth, as well as improving network traffic performance.
