【摘要】：无线体域网络比传统传感网络要求更高的数据传输可靠性和及时性,其可靠性属于数据包级可靠。提出了一种及时可靠的无线体域网络传输协议AODV-RT,该协议考虑到节点的存储资源受限和无线体域网络数据优先级,采用E2E(EndTo-End)、HBH(Hop-By-Hop)以及E2E与HBH相结合的错误恢复机制保证数据传输的可靠性。首先在每个节点缓存优先级别最高的警报信息,提供HBH错误恢复;其次通过在中间节点位置为接收信号强度RSSI较低的后一级节点缓存优先级别较高的数据包,提供E2E与HBH相结合的错误恢复;最后对低优先级数据采取E2E错误恢复。性能分析与模拟实验表明:该协议在数据传输率、端到端延迟和能量消耗等方面优于相似协议MAODV-SIM。
[Abstract]:Wireless bulk area network requires higher reliability and timeliness of data transmission than traditional sensor network, and its reliability belongs to packet-level reliability. This paper presents a timely and reliable wireless bulk area network transport protocol AODV-RT.The protocol takes into account the limited storage resources of nodes and the priority of wireless body area network data. The reliability of data transmission is ensured by using the error recovery mechanism of E2E EndTo-EndTo-EndPen (HBH- Hop-By-Hopp) and E2E combined with HBH. First, the alert information with the highest priority level is cached at each node to provide HBH error recovery; secondly, the higher-priority data packets are cached at the intermediate node location for the lower level of received signal strength RSSI. Provide E2E combined with HBH error recovery; finally take E2E error recovery for low priority data. Performance analysis and simulation experiments show that the proposed protocol is superior to MAODV-Simm in data transmission rate, end-to-end delay and energy consumption.
