Description: 用NS2仿真802.11b WLAN信道。指出现有NS2代码中的错误，给出SNR、BER的计算公式和代码实现。-Simulate 802.11b Channel within NS2
This document describes how to simulate one 802.11b channel in NS2. It focuses on how to
simulate wireless transmission error due to bad channel quality. That means BER need to be
considered to determine whether one frame is transmitted correctly. To get BER, SNR need to be
calculated. The following sections describe current simulation of transmission error in NS2, the
methods to calculate SNR and BER, and how to incorporate these methods into NS to achieve our
aim--- to simulate 802.11b channels as exactly as possible.

Description:
In today’s most of the Adhoc networks needs the reliable connection to transfer the data. Most number of
data packets loss is experienced in the Adhoc networks due to Transfer control protocol(TCP)’s high channel
error rate and link failure. To improve TCP performance in Adhoc networks a number of schemes have been
proposed, where Adhoc networks use the multi-hop wireless connectivity, where the network has quickly
changing network topology. ELFN (Explicit Link Failure Notification) is one mechanism to manage link
failures with dynamic cache update scheme to improve the TCP performance considerably. In this paper, we
propose a mechanism which significantly increases the throughput of TCP’s performance with ELFN based
Dynamic cache update scheme using Dynamic source routing protocol. Our simulation results using ns-2
simulator, mentions that our scheme can handle link failures in effective way, and improves TCP’s
performance considerably -
