Design of Efficient Transport Protocol for Multimedia through Wireless Networks

Abstract

Wireless Internet enables wireless connectivity to the Internet via radio waves. The rapid growth of wireless Internet, and broad band networking infrastructures, such as 3G and 3.5G, WLAN and WLAN-mesh and WiMAX, makes multimedia (audio and video) information available to us anytime, anywhere, on any device. The versatility of wireless internet has consumers demanding the service at an increasing rate. Therefore it is important to develop an efficient rate control protocol for the transmission of multimedia data through wireless networks which reduces all types of losses by satisfying multimedia constraints such as delay jitter, and to achieve a high throughput. In this approach, we make use of adaptive end to end loss differentiation algorithm for differentiating congestion losses from wireless losses and a function to differentiate burst wireless losses from transient wireless losses. Loss proportion increase and loss proportion decrease (PIPD) algorithm will be used for defining burst period in order to increase efficiency. Also evaluation will be performed by taking different decision factors into consideration and thus choose a suitable decision factor for reducing losses. The proposed approach can achieve high throughput, low losses, and good energy efficiency.
