Abstract: The broadcasting way for exchange of routing packets in wireless mobile network easily causes the packets lossing. A time division multiple access routing protocol (TDRP) based on cluster head coordination is proposed. The TDRP combines multiple access protocol and routing protocol. The transmission efficiency is improved, and the transmission delay is reduced by ensuring the reliable transmission of routing/control information. A multiple access protocol based on super frame structure is proposed. Under the manage span of the super frame, it uses TDMA for routing information exchange; and under the data span of the super frame, it uses CSMA/CA for data exchange. In order to control the media resources occupied by routing information, it designs the nodes login and logout processes so that the cluster head only distributes time slots for the nodes which have already joined the network successfully. Through the interaction of two-hop routing information between adjacent nodes, all nodes can get the three-hop routing table steadily, and the cluster head can get the complete routing table by the interaction of manage frames. The simulated results show that, compared with the existing AODV/OLSR routing protocol, the proposed protocol can reduce the average delay by 23% and improve the transmission efficiency by 30% under the mode of mobile group.
