A QoS-based Dynamic Scheduling Middleware of Wireless Multimedia Sensor Networks
نویسنده
چکیده
QoS guarantee in Wireless Multimedia Sensor Networks is considered. QDSM (QoS-based Dynamic Scheduling Middleware) is proposed. In QDSM, firstly a combined service QoS Model is established, secondly the application QoS requirement is interpreted and delivered to WMSNs by this model. Besides, a node schedule algorithm (NSA) based on QDSM is designed. Suitable type and number of sensor nodes can be scheduled. According to users' requirements, data can be collected, processed and transmitted by NSA. Mathematical proof and simulation results show the effectiveness of QDSM in QoS guarantee.

A Fuzzy Based Approach for Rate Control in Wireless Multimedia Sensor Networks
Wireless Multimedia Sensor Networks (WMSNs) undergo congestion when a link (or a node) becomes overpopulated in terms of incoming packets. In WMSNs this happens especially in upstream nodes where all incoming packets meet and directed to the sink node. Congestion in networks, if not handled properly, might lead to congestion collapse which deteriorates the quality of service (QoS). Therefore, i...
