In wireless sensor networks (WSNs), the surveillance cameras for prevention of crimes and disasters have been deployed.
An increase in the packet collisions, however, causes an increase in delay and a decrease in the delivery ratio when emergency camera images which are larger capacity than usual are collected.
This is because communication speed of WSN is low, usually lower than 1Mbps, considering low energy consumption.
This paper proposes a new scheme which achieves the low latency in collecting image data in emergency for IEEE 802.15.4
beacon-enabled mode, which is a typical energy-efficient WSN protocol.
In this scheme, the network functions as an energy-efficient WSN in the normal period.
Time slots for image data collection are dynamically assigned using
sleep periods, and the image data is transmitted to the sink node as soon as image data is detected in the emergency
period.
Simulation results show that the proposed scheme is effective. |
