Particularities of security design for wireless networks in small and medium business (SMB)

Small businesses often have small budgets, which often means no fulltime IT staff or no possibility to hire a security consultant to set up a wireless LAN properly. This paper tries to develop a methodology for designing security for wireless networks in SMB. There are more security options to choose from, when setting up a wireless network, thus the security features needed for a company must be carefully taken in consideration. The benefits from one security feature must be balanced with the implementation and maintenance cost and with the risk of not getting the security level wanted.security, wireless, communication networks

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

Providing Security to Wireless Packet Networks by using Optimized Security Method

Now-a-days technology is growing very fast, due to rapid development of the technology in computer arena, communication through network become a habit to the users. Communication through network is happen using two channels i.e., by connection oriented and connection less. At present users prefer wireless networks for communication and transferring data due to its flexibility. So in this paper we are focusing on wireless networking, as it is not reliable we are proposing an optimized security technique to provide security to the communication on wireless. In this paper we mainly focus on packet scheduling which plays the vital role in the transmission of data over wireless networks. We are using optimized security technique to secure the packets at initial level itself while scheduling the packets.
