Abstract:
In an ad hoc network, broadcast data communication is an unavoidable type of data transmission that provides synchronization, routing, and other messages to all the neighboring devices. Guaranteeing that all neighboring MTs receive broadcast messages is a hard task in multi-hop wireless ad hoc networks, especially when the traffic load is heavy. In this paper, we propose the sequential medium access control (SeMAC) protocol which aims at collision-free communication and reduced overhead for predictable broadcast message to sustain dynamic changes in network topology, as well as facilitate smooth operation of peer-to-peer unicast in multi-hop ad hoc networks SeMAC is intended to complement the IEEE 802.11 DCF function and is shown in this paper to greatly enhance the performance of broadcast and unicast communication of the IEEE 802.11.
