In this paper, we propose a new protocol for sensors Frequency Shift Keying data transmission named RF-Tania protocol framework. This protocol focuses on Energy Efficiency and it is based on an existent open source protocol stack. Tania protocol framework includes a set of three protocols: The Sensors Data Transmission Protocol (Tania-SDTP), the Ad-Hoc On Demand Protocol (Tania-AHOD) and the Ad-hoc...
We investigate joint information and energy cooperative schemes in a slotted-time cognitive radio network with a primary transmitter-receiver pair and a set of secondary transmitter-receiver pairs. The primary transmitter is assumed to be an energy-harvesting node. We propose a three-stage cooperative transmission protocol. During the first stage, the primary user releases a portion of its time slot...
Wireless transfer of energy through directed radio frequency waves has the potential to realize perennially operating sensor nodes by replenishing the energy contained in the limited on-board battery. However, the high power energy transfer from energy transmitters (ETs) interferes with data communication, limiting the coexistence of these functions. This paper provides the first experimental study...
In this paper, we present a new medium access control (MAC) protocol called Radio Triggered Sensor MAC (RTM) protocol that is expected for the next generation sensor network. The proposed RTM is a cross-layer MAC protocol which utilizes the passive radio sensor hardware for efficient medium access. The passive radio sensors harvest the energy from the wireless signal and energize itself. The passive...
