Receiver Initiated Transmission Strategies Applied to Street Lighting Systems Based on Wireless Sensor Networks

摘要

The draft document of the new IEEE 802.15.4e specification assumes receiver initiated transmission (RIT) to reduce energy consumption of wireless sensors by turning off the radio periodically, even if they operate in mesh topology. The original contribution from this paper is developing and evaluating the RIT strategies intended for street lighting systems using wireless sensor networks to control and monitor public lighting systems. This paper presents a new configuration strategies for the RIT mechanism based on mapping weights assigned to devices when routing the gradient, which provides better performance when compared to the energy consumed by the network, average end-to-end delay and end-to-end delivery rate. The experiments were performed using the simulation tool ns-2. Results show that the developed strategies make the use of RIT in urban networks feasible, according to the requirements specified in RFC 5548.
