| Abstract: | A multihop and mobile packet wireless network with IEEE 802 11 RTS/CTS multiple access protocol is presented. A comparison in throughput among slot ALOHA , carrier sense multiple access ( CSMA ) and it is made. In a packet wireless network, the robust clustering network structure can be achieved rapidly by the minimal identifier (ID) clustering algorithm with lower control information, and it is efficient to take advantage of multiple channels for the suitable medium access control (MAC) protocol. But it is unable to avoid the hidden terminal problem of CSMA due to two hop clustering structure in each cluster. However, the Request To Send (RTS) and Clear To Send (CTS) protocol can decrease the collision time of packet greatly so as to improve the network performance. |
