IEEE 802.11 networks successfully satisfy high data demands and are cheaper compared to cellular networks. Modern mobile computers and phones are equipped with 802.11 and are VoIP capable. Current network designs do not dynamically accommodate changes in the usage. We propose a dynamic power control algorithm that provides greater capacity within a limited geographic region. Most other power algorithms necessitate changes in 802.11 requiring hardware changes. Proposed algorithm only requires...
Show moreIEEE 802.11 networks successfully satisfy high data demands and are cheaper compared to cellular networks. Modern mobile computers and phones are equipped with 802.11 and are VoIP capable. Current network designs do not dynamically accommodate changes in the usage. We propose a dynamic power control algorithm that provides greater capacity within a limited geographic region. Most other power algorithms necessitate changes in 802.11 requiring hardware changes. Proposed algorithm only requires firmware updates to enable dynamic control of APs transmit power. We use earlier studies to determine the limit of the number of users to optimize power. By lowering transmit power of APs with large number of users, we can effectively decrease the cell size. The resulting gap is then covered by dynamically activating additional APs. This also provides greater flexibility and reduces the network planning costs.

Mobile devices capable of transmitting and receiving data over an 802.11 network have become very common gadgets in our society. Most small mobile devices available in the market today come with integrated 802.11 radio. The extraordinary growth of this technology has also introduced several worries regarding the vulnerabilities that exist by transmitting data over the air. In order to minimize such problems, encryption algorithms were added as an option to be used with 802.11. Unfortunately,...
Show moreMobile devices capable of transmitting and receiving data over an 802.11 network have become very common gadgets in our society. Most small mobile devices available in the market today come with integrated 802.11 radio. The extraordinary growth of this technology has also introduced several worries regarding the vulnerabilities that exist by transmitting data over the air. In order to minimize such problems, encryption algorithms were added as an option to be used with 802.11. Unfortunately, the usage of encryption algorithms also causes a faster depletion of the energy resources available to a mobile device. Depending on the encryption algorithm implementation, a greater number of packets may be required in order to transmit the same amount of data that would be transmitted with less packets over a non-encrypted channel. The objective of this research is to analyze and evaluate the affects that the encryption algorithms used by wireless security protocols can have during data transmission over a wireless medium.
