A Multipath Routing Protocol in Wireless Mesh Networks

Multipath routing protocols can effectively provide delay guarantees for delay-sensitive traffic such as live stream video over Wireless mesh networks (WMN). However, most existing multipath routing protocols rarely optimize the traffic over the multiple paths to promote network performance. In this paper, we propose a novel multipath routing protocol using convex optimization methods to formulate the problem and derive a multipath protocol through an optimization decomposition. Simulation results show that the proposed protocol dynamically and intelligently decomposes the contending traffic over multiple paths and hence efficiently supports delay-sensitive traffic.
