Virtual multipath routing for reliable data delivery in wireless sensor networks

  • Aiming at reliable data delivery in wireless sensor networks, VMR(virtual multipath routing) protocol was proposed. It integrated path optimization into data transmission so that data delivery quality was guaranteed at very little control overhead. In this protocol, paths were constructed on demand, and data was delivered along multiple paths. Meanwhile ATT(accumulated transmission times) of each packet from source to sink along a path were collected. Path quality information was fed back to source where low quality paths were identified and filtered out via interval estimation on the expectation of ATT. Route optimization was achieved step by step in this way. Simulation in NS2 platform showed path selection converges to optimal or suboptimal solution fast. VMR is competent to deal with adverse, dynamic, bandwidth constrained WSN network and outperformed typical reliable routing protocol AODV_ETX in both energy efficiency and reliability.
