Abstract: Achieving the best quality of service (QoS) as per user requirement is one of the important challenges. The time-critical applications in wireless sensor networks (WSNs) demand energy efficient transmission of data with limited resource availability. To resolve these issues, AQSDR has been proposed. The proposed protocol support packet differentiation and selection of sensor node based on energy, delay, and congestion for path establishment to transfer normal data packets providing energy conservation. The multipath is chosen for transmission of emergency packets satisfying delay requirements of non-delay tolerant applications. AQSDR support adaptive path selection, according to application requirement. The proposed technique in this work outperforms when compared with the existing protocol in terms of minimised energy consumption, delay, control overhead, packet drop ratio, and high throughput.

Keywords: clustering; congestion index; delay; energy efficiency; multipath; service differentiation; wireless sensor network; WSN; single path; TDMA; throughput; control overhead; packet drop.
