A Novel Conflict-free Broadcast Channel Scheduling Protocol for Wireless Sensor Networks
Broadcast is a efficient method that allows the nodes in the wireless networks share the data among other nodes.Because the transmissions of broadcast packet are related to receive of multi-nodes.it is difficult to ensure the reliable transmission of broadcast packet.In the wireless sensor networks,due to limitation of battery power in sensor nodes,it is more difficult to ensure the reliable transmission of broadcast.In the paper, a new synchronous MAC protocol,termed the Evolutionary Reliable Broadcast Protocol(ERBP).is introduced.In existing MAC protocols for WSN.the transmission of the broadcast packet consumes much energy,but the transmission reliability is IOW.In ERBP.we design a novel receiver-based conflict detecting mochanism and simple four-handshake process of the control packet to solve the problem.By simpfifying the handshake process of the control packet.using the periodic sleep scheme and the collision avoidance measures,it reduces the energy consumption.Through study of Energy-efficiency of the protocol.it is proved that the ERBP not only has high transmission refiability of broadcast,but energy-efficiency is better.
