  • Sandrasegaran, Kumbesan; Patachaianand, Rachod; Madani, Faisal; Lin, Cheng-Chung (IEEE, 2010)
    In this paper, a new opportunistic feedback protocol for orthogonal frequency division multiple access (OFDMA) systems with mixed realtime (RT) and non-realtime (NRT) traffic is proposed and analysed. Based on the proposed ...
  • Lin, Cheng-Chung; Sandrasegaran, Kumbesan; Reeves, Scott (IEEE, 2012)
    LTE is a purely packet-switched radio access technology and improves the legacy systems by supporting higher data rates with low latency. Release 8 of LTE has a number of gaps that prevent it from meeting the IMT-Advanced ...
  • Chen, Lu; Sandrasegaran, Kumbesan; Basukala, Riyaj; Madani, Faisal; Lin, Cheng-Chung (IEEE, 2010)
    Soft handover (SHO) provides better support for user mobility. The quality of service (QoS) to the mobile wireless subscribers can also grant benefits from SHO. To analyze the impact of SHO on the circuit switched (CS) ...
  • Lin, Cheng-Chung; Sandrasegaran, Kumbesan; Zhu, Xinning; Xu, Zhuliang (Hindawi, 2013)
    Coordinated multipoint (CoMP) transmission and reception is the key technique in LTE-Advanced to improve the cell-edge throughput and/or system throughput. Joint processing (JP) in CoMP technology provides multiple data ...

    Handover in LTE is purely hard handover. The use of break-before-connect handovers reduces the complexity of the LTE network architecture. However, the hard handover may result in data being lost. A Handover algorithm is ...
  • Xu, Zhuliang; Sandrasegaran, Kumbesan; Kong, Xiaoying; Zhu, Xinning; Hu, Bin; Zhao, Jingbin; Lin, Cheng-Chung (AIRCC, 2013)
    This paper presentsa new simple mobile tracking system based on IEEE802.11 wireless signal detection, which can be used for analyzingthe movement of pedestrian traffic. Wi-Fi packets emitted by Wi-Fi enabled smartphones ...
  • Xue, Minjie; Sandrasegaran, Kumbesan; Mohd Ramli, Huda Adibah; Lin, Cheng-Chung (IEEE Computer Society, 2010)
    This paper evaluates the performance of two simple packet scheduling algorithms for real-time traffic in the third generation partnership project long term evolution (3GPP LTE) system. These algorithms, known as Algorithm ...
  • Wu, Leijia; Al Sabbagh, Abdallah; Sandrasegaran, Kumbesan; Elkashlan, Maaged; Lin, Cheng-Chung (IEEE Computer Society, 2010)
    The next generation wireless network is expected to be a heterogeneous. The Radio Access Technology (RAT) selection algorithm, including initial RAT selection and vertical handover, is one of the key research areas in ...
  • Lin, Cheng-Chung; Sandrasegaran, Kumbesan; Mohd Ramli, Huda Adibah; Xue, Minjie (IEEE Computer Society, 2010)
    Long Term Evolution (LTE) is the next generation wireless system that uses Break-before-Connect technology in the handover scheme, unlike handover in the Wide-band Code Division Multiple Access (WCDMA) that uses ...
  • Mohd Ramli, Huda Adibah; Sandrasegaran, Kumbesan; Basukala, Riyaj; Patachaianand, Rachod; Xue, Minjie; Lin, Cheng-Chung (IEEE, 2010)
    Long term evolution (LTE) is the next generation wireless system that supports all IP transmission for multimedia services. The quality of service (QoS) requirements of multimedia services are one of the major challenges ...
  • Xu, Zhuliang; Sandrasegaran, Kumbesan; Hu, Bin; Lin, Cheng-Chung (IJARCSS, 2013)
    Received Signal Strength Indicator (RSSI) was deemed that it is not applicable for WLAN localization directly, as it is highly influenced by environment and limited by the measurement device. This distortion must be ...
