Abstract

Message Queuing Telemetry Transport for Sensor Networks (MQTT-SN) is a publish-subscribe communication protocol for Wireless Sensor Networks (WSN), which developed to guarantee the needed of publish-subscribe protocol which can be applied for sensor networks which doesn't have network interface. However, MQTT-SN has a weakness because by default MQTT-SN sends plaintext in transmission process, it proves that MQTT-SN don't guarantee security aspect of confidentiality. Security mechanism is needed to ensure confidentiality of MQTT-SN especially in its use as a communication protocol in healthcare system, because in health sector data confidentiality is important. Security mechanism to ensure MQTT-SN confidentiality has been conducted using Advanced Encryption Standard 128 (AES128), which is a conventional cryptographic algorithm with high computational process which not appropriate with WSN characteristics, in addition computational defects has been found in all types of AES, so an alternative algorithm is needed to replace AES. This research provides an alternative solution by applying end-to-end security mechanisms for publishers and subscribers using lightweight stream cipher Grain-128 on prototype electrocardiogram monitoring system based on MQTT-SN. The results showed that, this security mechanism successfully secured electrocardiogram data transmitted on MQTT-SN protocol from confidentiality. Grain-128 performs better than AES128 based on encryption time and memory usage.

Abstract

A growing number of internet users leads to a high amount of network traffic. Servers need to be added to avoid overload. Load balancing is also needed to distribute the load equally. Load balancing is widely implemented in SDN because it's programmable and flexible in a complex network. Therefore, this research proposes the implementation of load balancing in SDN using linear regression. The dataset for modeling linear regression function contains thirty samples. It contains the information of central processing unit (CPU), random access memory (RAM) and number of requests. The linear regression calculation is according to the server's CPU and RAM. The result is a prediction of the number of requests from each server. A server with the lowest request is chosen by the controller to handle the request. This research compares between linear regression and round-robin. In traffic distribution testing using linear regression, server with higher specifications gets more distribution than a server with lower specifications. In the testing of 300 requests per second, linear regression's response time is between 169.3 to 353.4 milliseconds, and round-robin is between 339.2 to 1232.6 milliseconds. Linear regression's throughput is between 241.5 to 310.7 KB/s, and round-robin is between 129.4 to 179.8 KB/s. In CPU utilization testing, the highest CPU usage in linear regression is 75 percent, and round-robin is 98 percent.

Abstract

VANET is a wireless network which using vehicle as a moving node for exchange information and provide comfort and security for vehicle user. Characteristics of VANET are high mobility and different number of vehicle. Number of vehicle in urban area is affected by activity on the area at certain hour such as rush hour in the morning and evening, this caused number of vehicle varies. Previous research stated that DSR is a reactive routing protocol that able to work in VANET and produces good performances based on overhead, packet delivery ratio, and normalized routing load parameter. This study presents an analysis of the effect of node density in VANET network using DSR in urban model area as the simulation. Testing is based on changes in the number of nodes using 30, 60, 90, 120, 150 and 300 nodes with testing parameters end to end delay packet and delivery ratio, also using coefficient determination, F test, and T test for validity testing. The result showed that node density impacted VANET performance when using linier regression for validity testing. The performance of VANET by using DSR produces the best end to end delay in 30 nodes with 3057.79ms, and the worst in 300 nodes with 25432.9ms, while in packet delivery ratio parameter produces the packet successfully sent in 300 nodes with 92.79%, and the least in 30 nodes with 76.88%.

Abstract

The process of education and learning in public schools has limitations on communication problems for the deaf. The communication process in public schools is based on verbal language, whereas the deaf rely on sign language to communicate. Based on this problem, an auxiliary communication tool is needed to carry out learning with deaf students. The systems used in the e-learning process can support the learning process of deaf students. The main feature in this learning process is converting voice into sign language in real-time. Two-way communication requires video, audio, and chat. The system is set up using Web Realtime Communication (WebRTC) as a real-time data transfer protocol using a browser.
