Fast Networks as a Candidate for LTE-Advanced Networks
Miyim, A.M.,Mahamod Ismail,Rosdiadee Nordin 한국산학기술학회 2013 SmartCR Vol.3 No.2
WiMAX, a technology that is based on the IEEE 802.16 standard air interface, is said to be a potential candidate for next generation (4G) wireless mobile systems. For the system to meet the requirements of LTE-Advanced/IMT-Advanced, it is expected to provide better cell coverage, improved performance and capacity, reduced latency, advanced mobility mechanisms, increasing peak data rates, and most of all to provide quality of service while integrating well with the complex nature of the entire network. This paper therefore, attempts to explain key parameters of the mobile WiMAX technology and developmental stages that make it the future 4G network structure. The focus is on the mobile WiMAX (IEEE 802.16m) specifications, salient features of layer 1 (PHY layer) and layer 2 (data link layer), with emphasis on the MAC sub-layer of the internet layer protocol stack, QoS and scheduler.

Hybrid Encryption of ElGamal-AES with Huffman Coding for Efficient Data Communication
Abdullahi Yahaya Yusuf,Farouk Lawan Gambo,Hyeju Shin,Abubakar Muhamad Miyim 한국디지털콘텐츠학회 2023 The Journal of Contents Computing Vol.5 No.2
Information security or data transmission efficiency and reliability are unanimously considered as some of the most important things that are required whenever communication between parties is to be established. Inefficient data security and improper management of voluminous data during data communication increases data transmission cost, delay in data transmission, and risk of confidentiality and privacy to the transmitted data. Thus, this paper proposes an improved cryptosystem to ensure reliability and efficiency to data in communication channel. The work adopted two cryptographic methods (ElGamal cryptosystem) for the asymmetric key distribution; Advanced Encryption Standard (AES) was suggested for message encryption. In the other hand, Huffman coding (compression algorithm) was introduced along the way to reduce the size of the data to be transmitted. The results of our proposed scheme show that the entropy ensures reliability and encryption time ensures efficiency to data in communication channel. This hybrid scheme is promising with a potential of improving data security.
