Dynamic traffic load balancing mechanism for SHAKE architecture

In the mobile ad-hoc network, we frequently experience the case where only the small bandwidth cell-phone links are available without sharing these expensive bandwidth´s, while high bandwidth wireless LAN link is available among end-stations. SHAKE, shared multiple paths protocol for cluster network, is the architecture using the mobile IP so as to share the multiple external cell-phone links via the wireless LAN link. Since the traffic load balancing in the existing SHAKE system is of static, the actual available bandwidth for the end-station goes to bad performance. This is because the available bandwidth for each cell-phone links is not stable and dynamically changed. In this paper, the dynamic traffic balancing mechanism for SHAKE system with available bandwidth measurement is proposed and is proposed and performed a preliminary evaluation. The prototype system implementing the proposed mechanism can achieve large performance improvement.
