Resource Allocation and Cross Layer Control in Wireless Networks Apr 2006
Resource Allocation and Cross Layer Control in Wireless Networks presents abstract models that capture the cross layer interaction from the physical to transport layer in wireless network architectures including cellular, ad-hoc and sensor networks as well as hybrid wireless-wireline. The emphasis in the presentation is on describing the models and the algorithms with application examples that illustrate the range of possible applications. Representative cases are analyzed in full detail to illustrate the applicability of the analysis techniques, while in other cases the results are described without proofs and references to the literature are provided. |

Radio Frequency Interference and its Use as a Weap

Radio frequency is a type of electric current on a wireless network, which emits an electromagnetic field when alternating current is applied to an antenna. Similar to waves that result from a rock thrown into water, radio waves are altered when obstructions appear, and may reflect or scatter for example, depending on their interactions with each other. (Shimonski, 2002) Wave fronts are generated when the waves become reflected. So from a receiver’s perspective, the wave fronts may be in or out of phase with the main signal as they reach the receiver at different times. If the peak of one wave is added to the peak of another, they are in phase and the wave will be amplified. If the peak of one wave comes in contact with the valley of another, they are out of phase, and the wave is eliminated.
Radio Frequency Interference occurs “when a signal radiated by a transmitter is picked up by an electronic device in such a manner that it prevents the clear reception of another and desired signal or causes malfunction of some other electronic device (not simply a radio or television receiver).” (Brock, Fall 1998) RFI can be induced intentionally, or unintentionally. |
