Many systems exist (TOA, AOA, RSSI) that can be used with diverse technologies (ultrasounds, infrared, Bluetooth, 802,11...) for indoor location. In this article we choose to apply TOA on a ZigBee network, to be able to add useful functionalities for other applications in an existing network and, in addition, achieve minimum consumption and low cost.

Article history: Available online xxxx a b s t r a c t This work reports an efficient and compact FPGA processor for the SHA-256 algorithm. The novel processor architecture is based on a custom datapath that exploits the reusing of modules , having as main component a 4-input Arithmetic-Logic Unit not previously reported. This ALU is designed as a result of(More)
