Abstract

Today's computer network is shifting from wired networks to wireless networks. Several attempts have been made to assess the performance of TCP over wireless networks. Also, several solutions have been proposed to improve its performance. Many people believe SCTP would be replacement of TCP. However, the performance enhancement research for SCTP over wireless network is in beginning stage yet. In this paper we have measured performance characteristics of SCTP, and compared with ones of TCP and TCP-snoop over wireless network. After this experiment, we found the performance of SCTP is better than TCP, but worse than TCP-snoop. To improve the performance of SCTP over wireless network, we modified SCTP code by adopting TCP-snoop approach. We named it SCTP-snoop. With this SCTP-snoop, we experimented again, and found that it showed the best performance over wireless network among TCP, TCP-snoop, and SCTP.
