Proposing of Collisions Free and Secure Network for IEEE 802.11 WLAN
IEEE 802.11 wireless network contains various problems such as packets delay and drop because of collision due to the heavy traffic. Packets are dropped either by the buffer overflow or by the MAC layer contentions. Such packet losses decrease throughput. Packet delay is also a result of poor utilization of network capacity when it is integrated with routing algorithms. Routing protocol contains very serious security issues in ad hoc network. SAODV, SEAR and SEED protocols are used for solutions. But when some security measures are taken it may results in decreasing the throughput.
