Survey of Bandwidth Enhancement of Microstrip Patch Antenna Using H Shaped Patch

Abstract: In wireless networks IEEE 802.11 standard is used which determines physical layer and media access control. There are many issues with wireless networks which do not exist in wired networks. For instance buffer sizing is one such issue. In case of IEEE 802.11 networks fixed buffer size leads to higher delays, under-utilization of channels. To overcome this problem dynamic buffer sizing is the desired solution. Li et al. presented novel algorithms for dynamic buffer sizing in order to increase throughput and reduce delay in Wireless Sensor Networks under various network conditions. In this paper we built a prototype application to implement these buffer sizing algorithms. The experimental results revealed that the algorithms are effective.
