| 摘 要： | 针对实时性设备接入传感器网络的需求,研究了传感器网络MAC层协议的保证时隙传送(GTS)竞争与传送协议,对可能的延迟作了估计并通过Petri网进行了仿真。仿真结果认为,在星型传感器网络中,当每个设备需求GTS1个时隙的时候,同时接入网络的设备不能超过7个,否则延迟将无法满足一般实时性要求,超过28个设备的时候某些GTS请求就会被拒绝 |
| 关 键 词： | 传感器网络 保证时隙传送 接入延迟 实时系统 |

| Abstract: | To guarantee Real-time communication in sensor networks, request and locating Guaranteed Time Slot (GTS) of IEEE 802.15.4 were researched. Petri net model about GTS request and locating were put forward. After simulation, it shows, in star sensor networks, if GTS request is more than 7 slots at same time, response time will be not satisfied the common real time system. If there are more than 28 slots, some request will be lost. |
| Keywords: | sensor networks guaranteed-times lot (GTS) response time real time |
