Strictly Prioritized Multihop Transmission of High-Priority Data Composed of Multiple Frames in Wireless Sensor Networks

Wireless sensor networks and their applications are becoming more diverse, and as an important future challenge, urgent high-priority data must be transferred with minimum delay and loss in a prioritized manner. This paper proposes strictly prioritized multihop transmission of high-priority data, composed of not only single frame but also multiple frames, by reserving the channel and exploiting medium access control coordination among sensor nodes on the route. Its effectiveness is shown through computer simulation.
