Newer applications for Wireless Sensor Networks, such as for video and audio applications, require higher data rates compared to traditional low data rate sensor network applications. Platforms with two radios were proposed to address these new classes of applications: each radio can send data on different routes to achieve high data rates and energy efficiency. In this work, we show that in heterogeneous dual radio networks the use of two disjoint paths is not enough to achieve maximal throughput. We present the novel disjoint paths with the same parity problem and how our system called Two Path Protocol (TPP) can improve throughput in dual radio networks. Our algorithm maintains energy efficiency and uses all the hardware resources available to improve end-to-end data delivery. We compare our design with FastForward, the state-of-the-art protocol for dual-radio in a real testbed. Experimental results confirm that our approach doubled the throughput getting very close to the maximum theoretical limit value.
