Extension of ReInForM Protocol for (m,k)-firm Real-time Streams in Wireless Sensor Networks

Bijun Li, Ki-Il Kim
2012 Journal of information and communication convergence engineering  
In this paper, a fault recovery scheme for (m,k)-firm real-time streams is proposed to improve the performance of our prior work, by contributing a delay-aware forwarding candidates selection algorithm  ...  Each node can utilize the evaluated stream DBP (G_DBP) and L_DBP values as well as the deadline information of packets to dynamically define the forwarding candidate set.  ...  This scheduling policy is used to evaluate the QoS performance of real-time streams and to better service them according to their (m,k)-firm requirements.  ...

Timeliness and QoS Aware Packet Scheduling for Next Generation Networks

Yao-Nan Lien, Yung-Chuan Wun
2009 2009 International Conference on Network-Based Information Systems  
We could enhance overall QoS without investing more resources if routers could forward packets based on their timeliness and QoS class giving important late packets proper precedence.  ...  We also developed a simple and effective scheduling policy based on this concept for the environments where each packet has a predefined hop-by-hop traveling schedule.  ...  There are several CBR streams simulating real-time traffic and a FTP stream simulating non-real-time traffic.  ...
