Demo Abstract: Smart Antennas Made Practical: The SPIDA Way

摘要: Smart antennas are a specific type of directional antenna able to dynamically control the gain as function direction. This contrasts with more traditional antennas, where dynamic ability is missing, and omnidirectional which designed have equal in all directions. Because these characteristics, smart may provide increased communication range by concentrating transmitted power towards intended receiver(s). also reduces contention on wireless medium, devices not involved transmissions less affected. Both features yield reliability at physical level, an asset for network functionality such routing protocols. Moreover, localization mechanisms take advantage angle-of-arrival information [1]. However, applying real-world sensor networks remains issue, due lack practical prototypes that can be easily integrated existing platforms. Some experiments reported tend large, costly, or impractical because need external [2]. A few solutions exist require advanced signal processing techniques, generally difficult implement resource-constrained devices. As result, most research involving has been hitherto carried out simulation. Confronted issues, we design build sufficiently inexpensive allow its integration hardware. We developed software enable use standard stack.
