Abstract

Dual-Radio platforms were proposed to improve the throughput of Wireless Sensor Network applications while conserving energy efficiency. However, current dual-radio protocols do not use all the hardware available. We model this problem as the minimum disjoint parity paths problem. We present the design, implementation and evaluation of SplitPath, a distributed routing protocol that computes two vertex-disjoint paths with the same parity. Unlike previous work on multipath routing, SplitPath is the first protocol to use multiple paths in dual-radio WSNs to achieve maximum throughput. The protocol was evaluated with experiments in the physical world. We compare our proposal with FastForward, the state-of-the-art protocol for dual-radio. Our approach improved the throughput by 60%, and achieved 96% of the maximum theoretical limit. (AU)
