Weak reliability and low energy efficiency are the inherent problems in Underwater Sensor Networks (USNs) characterized by the acoustic channels. Although multiple-path communications coupled by Forward Error Correction (FEC) can achieve high performance for USNs, the low probability of successful recovery of received packets in the destination node significantly affects the overall Packet Error Rate...
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...
