This paper proposes an adaptive bandwidth control scheme for autonomous distributed networks. Based on the consideration that the carrier sense multiple access with collision avoidance (CSMA/CA) is not efficient in terms of throughput due to its strict collision avoidance process, this paper employs a dynamic spectrum control (DSC) in which a certain number of discrete spectra having the highest signal...
Cooperative decoding is powerful technique for establishing good quality TV broadcasting. In cooperative decoding, some TV receivers, nodes, are cooperated, each other. These share the received information signal and thus obtain good quality information signal. Incremental-Maximum Ratio Combining (I-MRC) is one of the cooperative decoding methods. In I-MRC, the best condition's node and second one...
During recent years Wireless Body Area Networks (WBANs) have been experienced continuous developments by researchers both in academia as well as industry due to its capabilities and various promising applications, for instance, in the areas of healthcare, sports, military, etc. One of the crucial requirements in designing a WBAN, especially, for the healthcare applications is network reliability since...
When both a high-priority and a low-priority system share a common frequency band, the low-priority station must sense the presence of the high-priority system, and if required, postpone its transmission or reduce its transmit power to avoid possible interference. To compensate, transmission opportunities of the low-priority system should be ensured as much as possible. Using a transmission scheme...
This paper investigates the properties of social choice functions, that represent resource allocation strategies in interference coupled wireless systems. The resources can be physical layer parameters such as power vectors or antenna weights. The paper investigates the permissible social choice functions, which can be implemented by a mechanism in either Nash equilibria or dominant strategy - for...
