Description: Recently, IEEE 802.16j multi-hop relay network is proposed to increase data rate and coverage of the IEEE 802.16e networks. The Relay Station (RS) is introduced to relay the data from MR-BS to SS/MS or from SS/MS to MR-RS. We have studied the research area for a whole, and we proposed some improvements that could decrease the congestion opportunity of non-transparent RS using distributed scheduling. We have to modify the NIST WiMAX module which is implemented under the NS-2 in order to test the correctness of our proposed scheme. Subversion and Google-code-hosting are used to manage the project versions, thus we could be easy to modify the NIST module to support the functions of RS.

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 -
