    Abstract

    Energy-efficient transmission technique is a very essential performance decision factor for maximizing the lifetime of energy-constrained wireless devices such as Wireless Personal Area Network (WPAN) devices. Moreover, if the WPAN is operated in conjunction with a TDMA based scheme, the assurance of QoS requirements in the actual physical transmission at each allocated time slot is another important factor to be satisfied. We therefore propose an energy-efficient and QoS aware transmission scheme for WPANs operating in conjunction with a TDMA-based contention-free medium access protocol. The proposed algorithm determines the optimum combination of transmit power, physical data rate (i.e. modulation level) and fragment size required to simultaneously minimize the energy consumption and satisfy the required QoS in each assigned time duration. The proposed algorithm demonstrated the improved performance results in terms of throughput and energy consumption via computer simulations. Copyright 2007 ACM.
