An orthogonal spectrum sharing scheme for wireless sensor networks

Abstract It is not economically viable to allocate a dedicated spectrum band to wireless sensor networks (WSNs).Moreover, sharing a spectrum band with incumbent (primary) system compromises the reliability and performance of both the systems due to interference from one system to another.In this article, we address this limitation by proposing a two-phase orthogonal spectrum sharing protocol for a WSN which exploits multiple sensor nodes to click here effectively cancel out the interference from a WSN to read more the primary system, and vice versa.As a consequence, it is possible to achieve spectrum access for the WSN without compromising on the performance of either systems.Performance of WSN as well as the primary system is quantified in terms of average received signal to noise ratio.

We then validate the efficiency of the proposed scheme through analytical and simulation results.
