Curently, Wireless Sensor Network (WSN) is applied in many fields such as industrial plants, security, medical, as well as weather and environmental monitoring. The constraint of the use of WSN is the limited power of each sensor node, which means energy consumption efficiency is an important issue in WSN. Routing is a function in WSN which consumes a considerable amount of energy. One of the routing protocol that can increase the energy efficiency of WSN is Low Energy Adaptive Clustering Hierarchy (LEACH). In this research, energy consumption and the number of dead nodes of LEACH are evaluated using MATLAB simulation. The results show that elevation angle and number of clusters affect the energy consumption and number of dead nodes. HAP-WSN system with clustering topology will reduce energy consumption and minimize the number of dead nodes. From a set of simulations, it can be seen that energy consumption for 0° is greater than energy consumption for 10°. It can be also seen that the number of optimum cluster is 4 for both elevation angels.

Carrier Aggregation (CA) is ones of LTE-Advanced features, which can increase transmission bandwidth capacity by aggregating Component Carriers (CCs). The increment of bandwidth capacity depend to numbers of CCs aggregations. It can be two or more CCs aggregation, arranged by 3rd Generation Partnership Project (3GPP). There are intra-band CA and inter-band CA. Intra-band CA divided in two: intra-band contiguous CA and intra-band non-contiguous CA. This research aim to analysis the effect of CA and types of CA which can be optimum in Bandung city. Research start from planning and dimensioning LTE-Advanced radio access network in Bandung area using Atoll software. The scenario bandwidth configuration of CA maximum is 40 MHz and using two CCs by using frequency 1800 MHz and 2100 MHz. Simulation result show the network covered 100% of high speed internet user on simulation area. CA increase RSRP around 3 dB and decrease BLER around 0.02–0.07 %. Inter-band CA with PCell 1800 MHz and total bandwidth 40 MHz has the best mean throughput (43.35 Mbps).

This paper presents the simulation system of low power X-band weather radar based on frequency-modulated continuous-wave (FMCW) signal. The system uses a chirp baseband signal which 10–60MHz up-chirp signal and 60–10MHz down-chirp signal which is generated using Direct Digital Synthesizer (DDS) of AD9850 with 125MHz clock rate. The baseband signal is up-converted at X-band using a mixer with 9.035GHz Voltage Controlled Oscillator (VCO) to be transmitted at frequency of 9GHz. The system uses a bandpass filter (BPF) made of lumped elements to eliminate spurious signals produced by the DDS at the transmitter, and a lowpass filer (LPF) at the receiver. The system also uses a microstrip BPF of Square Loop Resonator (SLR)type as RF filter for X-band frequency. The results show that the system has 10–60MHz bandwidth for baseband signal with 10MHz cut-off frequency for LPF, while RF filter has the bandwidth response of 49MHz at the center frequency of 9.0015GHz.

LTE network optimization becomes an important part of the operation and maintenance procedures. Mobile operators need to reduce the number of errors, such as degradation or outage to provide quality services from the network. Automation is one of the challenges in making operation and maintenance procedures simpler. Self-healing is a domain of Self-Organizing Network (SON) which aims to detect, recover and compensate for the outage as well as possible. This study discusses the simulation of self-healing mechanism on LTE network, using RSRP (Reference Signal Received Power) parameter measurement. In this study the simulation is done using MATLAB R2016a software. The results show that the forward traffic that can not be served in the first simulation with SINR value of 13dB and 16dB is 49.72%. While the second simulation with higher SINR value that is equal to 18dB and 21dB which influence the increase in RSRP value, hence the percentage of average of forward traffic that can not be served decrease 0,94%. In the third simulation with a lower SINR value of 8dB and 11dB that affect the decrease in RSRP value, the percentage of forward traffic that can not be served to increase 1.01%.

In recent years, wireless LANs (WiFi) has been a popular options for mobile devices to connect to the network. As networks are becoming larger and more complex, solutions that simplify network operation and management are urgently needed. Software Defined Networking (SDN) is a state-of-the-art paradigm addressing this issue. While SDN is basically very general, in this work, networking performance related to the handover events is addressed in SDN-based wireless networks. For the investigation, Mininet WiFi, an extension to Mininet as the most popular SDN emulation environment, is used. Two association methods supported in Mininet Wi-Fi are Strongest-Signal-First (SSF) and Least-Loaded-First (LLF). These two methods has their own mechanisms. In this research, an experiment is conducted to observe how association control works in handover scenario. A performace analysis of transfer, jitter, and packet loss are also discussed. The result of the experiment is LLF gains better performance than SSF mode in every sub-scenario.

This paper will report the research about packet drop in NDN, especially those influenced by the distribution pattern of the delivery of interest and packet data from consumer to producer and vice versa. Packet drop that is too large will make packet delivery and data not run well because the interest in upstreams by the consumer can not be received back to the consumer as a packet data. NDN is a network architecture based on content named that will replace the function of IP technology, especially in networks that have topology in large scale. Simulation using NDNSim and topology using Palapa Ring, to examine the effect of packet drop, especially with the application of distribution method. The results conclude that using of Zipf Mandelbrot distribution pattern, can reduce the most significant packet drop probability compared to use of random distribution, The next sequence is on using of Exponential distribution patterns, but using uniform distribution, no reduction of packet drop probability in comparison with scenarios using random distribution.

In this paper, a design of square patch antenna with bandwidth widening using multiple slots is proposed. The resonant frequency of antenna is designed at the frequency of 5.3GHz for C-band application. The shape of patch antenna is square with the dimension of 12.3mm × 12.3mm. The antenna which has the total thickness of 1.6mm is fed by proximity feeding line through a 50Ω SMA connector. The number of slots are 7 located diagonally over the patch and separated 1.2mm each other which also produce circular polarization. Each slot has different length where the center slot has the longest length. To show the feasibility of bandwidth widening, a conventional antenna made of square patch without slots is also investigated. FR4 epoxy dielectric substrates with the relative permittivity of 4.3mm are used for both antennas. The simulation result shows that the −10dB bandwidth response of square patch antenna with multiple slots increases up to 210% compared to the conventional one demonstrating the feasibility of proposed method in enhancing the characteristic of square patch antenna.

The Method of Mel-Frequency Cepstral Coefficients Vector Quantization (MFCC-VQ) can be used in the speaker verification system. The process of feature extraction of speech signal using Mel Frequency Cepstral Coefficients (MFCC) vectors will produce acoustic speech signal. Vector quantization (VQ) is used to form the specific acoustic vector for each speaker. The introduction or verification, Sum Square Error is used to match unidentified speakers with speakers in filebase by the smallest error. In this research, the system is used to verify the speaker, namely red, blue, and green in Indonesian. This system has been tested by comparing the success rates between sound source speaker verification are used as filebase and modeling to the sound source said that is not used as filebase. From 20 times the pronunciation of each test the percentage of success obtained a good speaker verification. On testing the speaker with the same as filebase, the average percentage of verification success was 70%, while testing the speaker that are not used as filebase obtain an average percentage of 83.3% successful verification.
