Secure Wireless Infrastructure Network Using Access Point Checking

Developments in computers, communication and networks has opened up the doors for wireless network evolution which enjoys attractive features such as dynamic communication and the ease of members to join the network. Improvements in wireless technology has increased the needed for more complicated security systems, where data security and protection represent main wireless networks features. In distributed systems, the use of networks and standard communication protocols facilitate data transmission between a terminal user and a computer - and between a computer and another computer. Network security measures the need to protect data during transmission. Clearly, wireless networks are less secure compared to wired networks. So, the most important question here is how to protect data transmission in wireless networks. In this work, we briefly glance at network classes and existing security mechanisms. We then propose our new access point checking algorithm to increase security over infrastructure wireless networks. The goal is to save the time consumed during message travel from one host to another in the network, while maintaining message security. We employ a checksum mechanism to enhance message integrity. In addition, access point (AP) will check the message and decide whether the message should be sent back to the original sender or not. Experimental results for different networking scenarios are provided to validate the system ability. Our technique outperforms traditional security mechanisms in terms of timing characteristics
