Hardware comparison capturing received signal strength indication (RSSI) for wireless sensors network (WSN)
Wireless sensor network (WSN) is commonly used for localization analysis. Through sniffing receive signal strength indication (RSSI) in WSN system, localization of higher RSSI is connected automatically. This paper proposes the Raspberry-Pi (RasPi) based sensor node to sniffing RSSI and automatically connect the device to strongest RSSI. The RasPi brings the advantages of a personal computer (PC) to the domain of sensor network which makes it as the perfect platform for interfacing with a wide variety of external peripherals. Comparative analysis of its key elements and performances with some of current existing wireless sensor nodes has shown that despite the few disadvantages, the RasPi remains an inexpensive single board computer (SBC) with its very successfull use in sensor network domain and diverse range of research applications.
