Location based Multi-Queue scheduler in wireless sensor network

Recent advances in technology realize small devices which have been enabled wireless communication among sensors. Wireless sensor network is used for monitoring such as environment, earthquake and disaster. In sensor network, real-time end-to-end data communication is very important. If we use traditional First Come First Serve(FCFS) scheduler, which needs a lot of time to send if a packet generated from leaf nodes which is the nodes in end of the network. To reduce the amount of exceeded deadline packet, intermediate node need to change delivery order among packets in its ready queue. In this paper, we propose Multi-Level-Queue scheduler scheme which use different number of queue according to location of node in the network. The simulation result shows that our proposed scheme reduces the Miss Ratio of packet.
