| 摘 要： | 传感器网络(Wireless Sensor Networks, WSN)的事件检测型应用中,如何通过可靠性维护来保证在检测到事件时报警信息能及时、可靠地传输到监控主机至关重要。通过对不可靠的无线链路和网络传输的分析,提出多路冗余可靠性维护算法MPRRM。通过解析方法和仿真分析证明,该算法在可靠性、误报率、延迟和消息开销量上比同类算法具有优势。

| Abstract: | The reliability maintannace of the wireless sensor network is a key point to keep the alarm messages delivered reliably to the monitor center on time in a event detection application. Based on the unreliable links in the wireless sensor network and the network charateristics of an event detection application, MPRRM, a multiple path redundant reliability maintanace algoritm was proposed in this paper. Both analytical and simulation results show that the MPRRM algorithm is superior to the previous published solutions in the metrics of reliability, false positive rate, latency and message overhead. |
