Performance Evaluation of IEEE 802.11b, IEEE 802.11g and GPRS/EDGE Based on Query Retrieval Time

In this article, two popular database connection types of mobile devices, which are Windows Authentication over IP (internet protocol) and IIS (internet information services) [1], are used and IEEE 802.11 standards, namely IEEE 802.11b and IEEE 802.11g, and GPRS/EDGE technology are evaluated with respect to query retrieval time of different number of attributes and records. In both concepts, it is obvious that a successful connection can be established, but some differences occur on query results retrieval time as the database grows. Experimental results pointed out that while using IIS connection method IEEE 802.11b has less query retrieval time than IEEE 802.11g and GPRS/EDGE, in contrast to this, IEEE 802.11g is obviously time superior than IEEE 802.11b and GPRS/EDGE while using IP connection method.
