Transmission Rate Control in Heterogeneous Wireless Networks Using Multiple Connections

Abstract

In this paper, we propose a method that wireless mobile nodes can obtain high throughput in heterogeneous wireless networks using multiple connections and it has low packet loses under handover situation. Currently, a mobile node exchanges data with server for one network connection. The proposed method can use high throughput because it doesn't only use one network(WLAN, 3G, etc.) but also use multiple wireless networks.When mobile nodes move to area to use multiple connection, mobile nodes request heterogeneous wireless networks using multiple connections message from the server and the server transmit packets using multiple connections. Also, this method doesn't disconnect previous networks, so packets losses are decreased. Using the NS-2 simulation, we verify that the propose method enhances throughput.

Freeze Dead Line Algorithm for Vertical Handoff in Heterogeneous Wireless Networks

“…Another proposed solution is Cross-layer methods [4,5], which deliver some information from the bottom layer to the upper layer.…”
