Reduction of Transmission Delay of Low Priority Sensor Data Messages during High Priority Sensor Data Message Transmissions
Megumi Takahashi, Hiroaki Higaki (Tokyo Denki Univ.)
Abstract (in Japanese) (See Japanese page) 
(in English) Wireless sensor networks are for sensor data transmission from a wireless sensor node to a sink node with help of intermediate wireless sensor nodes which forwards sensor data messages along a wireless multihop transmission route. For achieving shorter transmission delay in transmissions of high priority sensor data messages, verious priority-based transmission methods for 1-hop and multihop wireless transmissions have been proposed. However, most of the methods do not consider longer transmission delay of low-priority sensor data message transmissions. This paper proposes a novel method for reduction of transmission delay of low priority sensor data messages by buffering them into wireless sensor nodes nearer to the sink node even though they are out of their origianal wireless multihop transmission route under a condition that they never interfere the transmissions of high priority sensor data message transmissions. Simulation experiments show that the proposed method achieves 3.49%-12.2% reduction of transmission delay of low priority sensor data messages. In cases that the sink nodes are on or near the edge of the wireless sensor network, higher performance improvement is achieved. Thus, the proposed method is better to be applied to such sensor network.
