tailieunhanh - The dynamic buffer sizing strategies for 802.11 based wireless networks

The widely used general rule-ofthumb is to have buffers size as the bandwidth-delay product (BDP) of the network, In this paper we argue that the use of the fixed size buffers in based wireless networks results in either undesirable channel underutilization or unnecessary high delays and the increased packet loss. Our objective is to maintain high network utilization while providing low queuing delays in wireless networks through dynamic buffer sizing algorithms. | ISSN:2249-5789 Santosh Hosamani et al, International Journal of Computer Science & Communication Networks,Vol 2(2), 218-223 The Dynamic Buffer Sizing Strategies for Based Wireless Networks Santosh Hosamani1, 1 Student, Department of Computer Science & Engg, R V College of Engineering, Bangalore () 2 Associate Professor, Department of Computer Science & Engg, R V College of Engineering, Bangalore (nagarajgs2000@) Abstract Wireless networks face a number of fundamental issues that do not arise in wired networks. We consider the sizing of network buffers in based wireless networks. is a set of standards for implementing wireless local area network (WLAN) computer communication using different frequency bands. They are created and maintained by the IEEE LAN/MAN Standards Committee (IEEE 802). All internet routers contain buffers to hold packets during the time of congestion. Buffers are used to reduce the packet loss and to ensure high link efficiency. The widely used general rule-ofthumb is to have buffers size as the bandwidth-delay product (BDP) of the network, In this paper we argue that the use of the fixed size buffers in based wireless networks results in either undesirable channel underutilization or unnecessary high delays and the increased packet loss. Our objective is to maintain high network utilization while providing low queuing delays in wireless networks through dynamic buffer sizing algorithms. Keywords: Wireless LAN, , TCP, Buffer Sizing. 1. Introduction Buffer size refers to the size allocated for temporary storage of data. Buffers are used at network routers to temporarily store incoming packets when the arrival of packets received exceeds the capacity of the egress link. Buffer sizing is an active research topic in the wireless network community. In communication networks buffers are used for the short time packet bursts. The importance of buffering .
