Adaptive TDMA Based QoS-Aware MAC protocol for Hierarchical Wireless Sensor Networks
Abstract— This paper presents an adaptive time division multiple access based energy efficient medium access control (ATDMA-MAC) protocol to handle the variable traffic load while maintaining the quality of service (QoS) assurance for delay-sensitive applications. The ATDMA-MAC protocol dynamically allocates time slots to the sensor nodes based on their queue length information to achieve minimum latency for a wide range traffic load. Furthermore, the analytical model of energy consumption has derived to demonstrate the superiority of the ATDMA-MAC protocol. Simulation results show that the proposed ATDMA-MAC protocol sends more data against existing TDMA based MAC protocols with minimum transmission latency and energy consumption.
