摘要：
It is challenging to deal with the tradeoff between energy efficiency and Quality of Service (QoS) for multimedia applications in Wireless Sensor Networks (WSNs). The packet aggregation scheme is widely applied to reduce overhead for high throughput and energy saving in wireless sensor networks. However, it may cause unacceptable delay in WSNs. In order to solve the problem for voice delivering with energy efficiency and proper QoS in WSNs, in this paper, we propose an adaptive waiting packet aggregation (AWPA) algorithm. First, we formulate the problem as an optimization problem. Then we optimize the problem and implement the proposed algorithm. Furthermore, we analyze the performance of the proposed algorithm. Finally, we conduct simulations in the NS-2 plafform to evaluate the performance. The results show that AWPA outperforms existing algorithms for the performance.
