Multi-hop Transmission and Routing with Hierarchical Modulation
Hierarchical modulation multiplexes layers of different robustness into one stream. Usually being exploited in broadcast systems such as digital video broadcasting, hierarchical modulation can also be applied to unicast communications in a cooperative manner. This article deals with novel multi-hop cooperative transmission and routing strategies with hierarchical modulation. In multi-hop networ...
متن کاملEnergy-Efficient Routing in Frequency-Hop Networks with Adaptive Transmission
We describe and evaluate an energy-efficient protocol for routing traffic in frequency-hop (FH) store-and-forward packet radio networks that employ an adaptive transmission protocol. The adaptive transmission protocol allows the radios to adjust the power in the transmitted signal and the rate of a Reed-Solomon code to respond to variations in partial-band interference and propagation loss. Rou...
متن کاملMulti-Hop Transmission: Benefits and Deficits
Sensor networks are supposed to operate with very little energy, are build of tens to thousands nodes and may be spread over large distances. In order to interconnect nodes in large areas while spending little energy, a self-evident approach is to use sensors as relays, thus saving transmit power while improving connectivity. In other words, nodes are not necessarily directly connected to a bas...
متن کاملAn Efficient Hierarchical Modulation based Orthogonal Frequency Division Multiplexing Transmission Scheme for Digital Video Broadcasting
Due to the increase of users the efficient usage of spectrum plays an important role in digital terrestrial television networks. In digital video broadcasting, local and global content are transmitted by single frequency network and multifrequency network respectively. Multifrequency network support transmission of global content and it consumes large spectrum. Similarly local content are well ...
