An Approach to Minimize the Use of Rts/Cts Handshaking Protocol in WLAN
Keywords:
Wireless Network, handshaking protocol, RTS/CTSAbstract
The rapid growth of computer network takes the concentration of researchers in the era of wireless network. There is a need of improving the performance of RTS/CTS mechanism. An increase in performance using RTS/CTS is the net result of introducing overhead .If network doesn't have any hidden nodes; the use of RTS/CTS will only increase the amount of overhead, which may reduce throughput. In this case, the additional RTS/CTS frames cost more in terms of overhead than what we gain by reducing retransmissions. Moreover, usage of RTS/CTS is helpful especially when data frame is much longer than RTS frame. In this dissertation, the focus is on the problem with RTS/CTS protocol. Here we studied that the performance of RTS/CTS handshaking mechanism degrade if system having few number of hidden node. To overcome this problem proposed methodology tends to maintain hidden table by each node of network that contain the information about hidden node of its neighbor node. The Proposed methodology reduce transmission overhead induced by optimized RTS/CTS exchange for improving throughput performance of IEEE802.11.
