Multipath routing has been employed to improve the network throughput, to provide load balance and to achieve reliability for many years in both wired and wireless networks. In wireless networks, the communication cost of the multipath construction scheme is at least polynomial. In this paper, we focus on the problem of how to chose a right position to deploy a wireless sensor node such that the existence of

multipaths, which connect a wireless sensor node and the data sink, is guaranteed. Traditionally, at a given position, the communication cost of the multipath existence checking is at least polynomial through using a multipath construction scheme. To reduce the communication overhead, we propose a simple and efficient multipath existence checking scheme, which incurs only a constant communication overhead.
