Optimized congestion control in TCP with Multi-Path support over Wireless Mesh Network

摘要

Wireless Mesh Network (WMN)[1] is a group of wireless devices that has function to transfer all data over wireless channel and it is able to self-organized, self-configure network path itself by optimize routing protocol over Layer 2 (MAC Layer). The WMN can be installed by using computer or device with interface base on IEEE 802.11 forming to the WMN. This network can provide services with any content as wiring network. In IEEE 802.11s[2] is standard for Wireless Mesh Network (WMN) which improve the communication protocol in Layer-2 (MAC Layer), using the Hybrid technic from the advantage of ad-hoc base and tree base for routing with path in WMN. With the wireless network standard came from IEEE 802.11a/b/g standard which does not define to build for the WMN and is different from the wireless access network (2G/3G Cellular systems, WLAN hotspot) [1].Wireless Mesh Network is consisted of three type of node; Mesh Portal (MPP), Mesh Point (MP), Mesh Access Point (MAP) [1]. All devices came with IEEE802.11 Standard and beyond - i.e., the physical layer link base on CSMA/CA[3] and standard TCP that work well with Wire Topology but may not suitable with WMN and optimize is in required. Regarding TCP/IP Model, many researches are focused to optimize any layers from physical to application. This research would be focused on the method to optimized congestion control in TCP with Multi-Path support over wireless mesh network.
