Performance Optimization of Codec in VOIP using Raspberry Pi

By Gomathinayagam.P S. Jayanthy

DOI: https://doi.org/10.5815/ijem.2018.02.06, Pub. Date: 8 Mar. 2018

This paper aims in design and implementation of Voice over Internet Protocol (VoIP) system with a high compression rate. The system uses a Raspberry Pi B+ ARM 11 microcontroller which is faster in processing the audio signal by means of CODEC2 software. An Audio Adapter (CM-108 or 109) is interfaced with the Raspberry Pi, which acts as a bridge in providing the processed voice signal to Raspberry Pi in its required PCM format. The setup is implemented in Local Area Network (LAN) in which the data transmission occurs. During the transmission of the data, the wireshark software was used to analyze the data in the network. A detailed analysis of the comparison results of different CODECs for compression rate and the estimated frame sizes are given. From the results, it is proved that the use of CODEC2 is an efficient system for VoIP. For secure communication, the AES encryption protocol with static private key was implemented. The 3.2Kbps compression technique is suitable for VoIP system as it has high compression rate and less delay compared to the other systems.

Development of Cloud Based Incubator Monitoring System using Raspberry Pi

By Mala Sruthi B S. Jayanthy

DOI: https://doi.org/10.5815/ijeme.2017.05.04, Pub. Date: 8 Sep. 2017

Accurate and quantifiable measurement of light is essential in creating desired outcomes in practical day to day applications such as in Poultry Industry. Light measurement is essential in ensuring the efficiency of egg hatching process. Artificial incubation has been used in the poultry farm for hatching of the eggs. For better hatching of the eggs, the temperature and humidity has to be maintained properly. The proposed system is equipped with DHT11 sensor which monitors the temperature and humidity of the incubator and continuously updates to the cloud through Wi-Fi. Remote user checks the temperature and humidity values and controls the intensity of the bulb through an Android app in his mobile phone. A servo motor is attached to the egg turner kept inside the incubator and is rotated according to the specified delay in order to prevent the yolk from getting stick to the shell of the eggs and also to provide uniform temperature for the eggs. From the experimental results, it is inferred that better hatching of the eggs could be achieved by controlling the intensity of the bulb remotely.
