We compare the performance of the simulated and semi-analytical throughput values in terms of average signal to noise ratio (SNR). In the investigated system, OFDMA is combined with adaptive modulation and coding (AMC) technique based on distinct modulation and coding

This strategy is implemented for orthogonal frequency division multiplexing (OFDM) systems with channel state information (CSI) feedback. Low density parity check (LDPC) codes are utilized

The aim of this model is to optimally distribute power in an efficient manner according to the particular irrigation demand of a crop in each irrigation line. The results demonstrate that our proposed method is more efficient and economical in terms of power distribution as compared with the traditional method. Besides, it guarantees an efficient irrigation without affecting crop quality and yields. The irrigation time is considered as important factor in the optimization equation. This optimization formula has been solved using Lagrange multiplier method to minimize the required power and optimally distribute power among water pumps.

The aim of this system is to schedule irrigation according to the particular requirements of a crop and to the change in various climatological parameters and other factors. This is to avoid over- or under-watering which significantly affects the crop quality and yields using the proposed algorithm. Moreover, our algorithm reduces the power switching, hence it conserves energy. The results demonstrate that the fuzzy model is a quick and accurate tool for calculating evapotranspiration as well as the required net irrigation. Additionally, we introduce a general algorithm as a part of the proposed system to calculate the irrigation time, which well suits both micro-irrigation methods: sprinkler and drip irrigation.

The goal is to implement an intelligent irrigation system based on wireless sensor networks and fuzzy logic. This system estimates irrigation amount and schedule needed to be applied under deficit irrigation. The PAN coordinator uses this schedule to employ an energy saving technique for both: irrigation system and sensor network. Thus, it prolongs the sensor's lifetime and conserves irrigation water. The performance of the system was analyzed using MIXIM framework for OMNeT++ simulator. The simulation results show that our system is efficiently thrifty in terms of consumed power and water besides its adaptive and accurate performance. In addition to its suitability for various irrigation systems and equipments, it is also appropriate for different locations and weather conditions.

In this work, we propose and simulate a simple and eco- nomic wireless sensor network architecture composed of only a single sensor node per lane, as a replacement to induc- tion loops to be used in intelligent transportation systems. The results show that our work enhances the average vehicular waiting and travel times as compared with fixed-time signals, which produces significant change by a factor of almost 40%.
