We propose a joint channel selection and quality aware routing scheme for multi-channel
wireless sensor networks to improve the network lifetime. A data collection traffic pattern is
assumed, where all sensor nodes perform periodic sensing and forward data to a
centralized base station (sink). The proposed scheme achieves improvement of the battery
lifetime by reducing the energy consumed from overhearing and also by dynamically
balancing the battery lifetimes of nodes. Performance evaluations are presented from …

We propose a joint channel selection and quality aware routing scheme for multi-channel
wireless sensor networks that apply asynchronous duty cycling to conserve energy, which is
common in many environmental monitoring applications. Energy resources may vary from
node to node due to differential consumption as well as availability, as observed in
rechargeable sensor networks. A data collection traffic pattern is assumed, where all sensor
nodes periodically forward sensor data to a centralized base station (sink). Under these …
