英文摘要 | Real-time data communication among and battery lifetime of sensor nodes turn into critical issues, due to the rapid development of wireless sensor networks over recent years. This paper presents a multiple priority queue-based system involving (1) a multiple priority queue mechanism to ensure data packet transmission in a real-time system, (2) a finite-size queue for realistic circuit design, (3) an N-policy M/M/1/K queuing model to avoid an energy hole problem, (4) a sleep mode to reduce the battery power consumption for lifetime extension and (5) a birth-death process to compute the probabilities of the sleep, idle, busy and transmit states. The probability in each state is obtained versus the data arrival rate, the service rate, the collision probability and the queue threshold. A high priority queue is validated to provide a shorter delay time, and the power consumtion is minimized with the threshold N as well. |
