Abstract

This paper presents the impact of different antenna strategies for localization scenarios evaluation, based on ZigBee wireless sensor networks (WSN). On our first strategy the Received Signal Strength (RSS) is measured and evaluated using a chip antenna on the mobile unit, and a patch antenna on the WSN fixed nodes. Then, we present another strategy where all fixed nodes are exchanged by a new type of antenna called Hive5, a sectorised antenna that combines RSS and Angle of Arrival (AoA) in the same node. This antenna will improve significantly the localization system, either in resolution, and/or cost.
