Routing protocols play important roles in mobile adhoc network performance. The Protocols find and decided the communication path with the routing algorithm to deliver the data along the networks. Channel qualities in wireless communication are an important factor in network performance. Previous research in routing protocol development did not much pay attention in this matter. This paper shows the routing algorithm which not concern with this channel quality cannot adapt well in Mobile Adhoc Networks (MANET). We evaluated reactive routing protocol in deterministic and probabilistic propagation models, which are two-rayground and shadowing. These models are used to predict the received signal power of each packet. The result shows the degradation of routing protocol performance in more realistic environment, which is shadowing propagation model. Then we used mathematical analysis based on throughput performance related to the probability of error and Signal to Noise Ratio (SNR). Routing protocols face uncertainty in link quality when the topology of the network became dynamic. The routing protocols have to consider channel quality in the link transmission to acquire higher throughput performance.

There are must-to-do steps in the nano-satellite development process, including the engineering model and flight model test. The atmospheric balloon test can be used to analyze the On Board Data Handling (OBDH) performance. The obtained results from the test are 13 images data captured from the 2900 MASL maximum altitude, also the sensor data i.e. temperature, pressure, humidity, position, and the direction of the balloon payload.

In this paper, we study an implementation of the Benjamini-Hochberg's procedure for cooperative multiband spectrum sensing in cognitive radio. We propose to use equal gain combining on forwarded p-values from cooperative cognitive radio (CR) users as the test statistic at the fusion center. By doing so, the distribution of the test statistic under the null hypothesis at the fusion center does not vary with different number of samples and types of local detectors. Simulation results show that the familywise miss detection rate (FWM) significantly decreases as the number of cooperative CR users increases. This means that the interference to a primary user due to the decision errors in spectrum sensing significantly decreases. Thus, p-value based cooperative multiband spectrum sensing using the Benjamini-Hochberg's procedure is well motivated.

The existance of wireless technology indirectly take huge positive and negative effect on all organism on this earth especially plant. On previous research held by Racuciu, Lftode, and Miclauss said there is an effect on corn plant growth which treated by electromagnetic waves in 1 GHz frequency. The objective of this research is to prove the effect of electromagnetic waves on the plant in microgravity environment. In this research, 2.4 GHz electromagnetic waves were used and the testing environment will be used clinostat.

In this paper, a full wave finite difference time domain (FDTD) computation method based on cylindrical coordinate system is proposed for calculating the resonant frequency of circular cavity resonator. The use of FDTD method with cylindrical coordinate system instead of Cartesian coordinate system is considered due to the geometry shape of analyzed structure, i.e. circular cavity resonator. In the computation, a hollow circular cavity resonator made of perfect conductor with the radius of 50mm and length of 100mm is discretized based on cylindrical coordinate system and numerically computed to determine its resonant frequencies. To verify the proposed method, the theoretical approach for the cavity is carried out by calculating its resonant frequencies for correspondent resonance mode. In addition, a simulation for determining resonant frequencies of the cavity is also conducted using finite element method (FEM) commercialized software. It shows that the FDTD computation result demonstrates an acceptable accuracy compared to the theoretical approach with the discrepancy less than 5% although it is worse than the result of FEM commercialized software.

In this paper discusses about performance analysis of Gigabit Passive Optical Network (GPON) with splitting ratio 1:64. The network topology is simulated using software tool called Optisystem. The transmitter uses a laser components with NRZ modulation scheme and the transmitter power is adjusted to maximum power according to the ITU-T standards. The transmission channel, used a fiber optic cable Single Mode Fiber (SMF) G.652 with a length of 20 km, as maximum length of PON technology, and the cable attenuation of 0.35 dB/km for wavelengths 1310, 1490 nm and 1577 nm. The research concluded that based on link budget, rise time and BER analysis, the performance GPON with 1:64 splitting ratio is not good to be implemented for provide broadband services.

Wireless channel with the presence of Line of Sight (LOS) is often modeled as Rician distribution. In order to track the channel for mobile users, exponentially weighted Least Squares (LS) Single Input Multiple Output (SIMO) channel estimation is employed. By incorporating the optimum forgetting, the system performance in terms of tracking Mean Square Error (MSE) and Bit Error Rate (BER) is evaluated. It is shown that the optimum forgetting factor as well as the system performance, are elevation angle-dependent due to the rapid movement of the user in the coverage area.

In this paper, the development of linear frequency modulated continuous wave (LFM-CW) radar is proposed using GNU radio and USRP. The use of GNU radio which is frequently implemented in software define radio (SDR) is to simplify the development especially in the modulation process of FMCW radar. The beat frequency filter for LFM-CW radar with components for distances of Om and 3m is applied for the realization of GNU software into radio and applied on the USRP. The signal level at receiver will change inline with the variation of target distance. If the target range is further the signal level shrinks. Signal receiver particularly vulnerable to interference noise when the distance is far. LFM-CW radar waves are generated using GNU Radio and USRP already meets the specifications. The radar is implemented in GNU Radio is also capable of detecting one or three targets at varying distances. The difference in the frequency spectrum owned chart on GNU Radio and MATLAB® occurs because the graph GNU radio frequency spectrum, frequency components are taken only positive frequency components, while the negative frequency components are ignored.
