    Position-based, energy-efficient, centralised clustering protocol for wireless sensor networks

    No full text
    We propose a position-based, energy-efficient, and centralised clustering protocol for wireless sensor networks. The protocol aims at prolonging the network lifetime by evenly distributing energy load among sensor nodes in the network. A new cluster head selection algorithm is developed in the proposed protocol. In addition, the protocol uses a novel multi-hop routing approach for inter-cluster communication between cluster heads and the base station. The performance of the proposed protocol is evaluated and compared with three existing clustering-based protocols. Simulation results show that the proposed protocol achieves better energy efficiency and longer network lifetime.Lifang Lu and Cheng-Chew Lim

    Predictive Modeling and Control of Energy Demand for Hybrid Electric Vehicle Systems

    No full text
    In this paper, the predictive and optimal control problem of energy consumption is investigated for hybrid vehicle systems. In order to make the energy usage more efficient (minimizing the energy demand), observations of drivers’ behavior are taken into consideration in analysis and predictive control design. Real world driving experiments are conducted to illustrate the effective and accuracy of the proposed new design techniques.Di Shen, Cheng-Chew Lim, Peng Sh

    Joint backoff control in time and frequency for multichannel wireless systems and its Markov model for analysis

    No full text
    A new joint random access scheme is proposed to enable effective uplink access when users are partially aware of channel conditions in multichannel wireless systems. The proposed scheme mitigates packet collisions with joint backoff control in the time and frequency domains, cooperating with a sensing method that exploits the channel conditions. The performance analysis of the joint access scheme is facilitated by a Markov model that provides a closed-form throughput expression. Simulation results show that this channel access scheme, working together with a simple sensing method, offers significant improvements to system throughput.Hyukjin Lee, Cheng-Chew Lim, Jinho Cho
