Several works have shown that the virtual coordinate based routing protocol has better performances than the real coordinate when the network density is low. However, unit disk graph model is adopted in most of those works. Many recent experimental studies show that wireless links among low power radios are unreliable. This has severe impacts on the performances of the routing protocols. In [1], the virtual geographic information proposed adopts unit disk graph model. In this paper, three new simple and effective strategies that take the unreliable links into consideration are proposed for constructing virtual coordinate in wireless sensor networks. We simulate the greedy routing protocol which uses the virtual coordinate constructed by our proposed strategies under unreliable links. Simulation results show that the delivery ratio of our proposed strategies is higher than the delivery ratio of the existing one, and closer to the delivery ratio of the real coordinate under unreliable links, without introducing any additional cost.
