The ultra wide band transmission present the effective solution for the precise ranging and high data rates applications. Standard IEEE 802.15.4 defining PHY and MAC layers for the low power wireless devices was in 2007 extended by amendments aiming to include the ultra wide band frequency bands in order to react on the demands for the ranging and high data rates low power applications. This standard...
This paper deals with the energy efficient issue of cryptographic mechanisms used for secure communication between devices in wireless sensor networks. Since these devices are mainly targeted for low power consumption appliances, there is an effort for optimization of any aspects needed for regular sensor operation. On a basis of utilization of hardware cryptographic accelerators integrated in microcontrollers,...
Due to a low installation cost of communication infrastructure, Low Power Wireless Area Networks (low PAN) presents an efficient solution for home and building automation. The low PANs operate in a microwave radio band that is often shared by several home appliances. Laptops, wireless routers, cordless phones and microwave ovens occupy the 2.4 GHz band without any channel allocation and thus interoperability...
