Multichannel dynamic-path forwarding protocol for wireless sensor networks
Asic System · 2014
To improve the performance of wireless sensor networks in heavy traffic conditions,a multichannel dynamic-path forwarding protocol( MDFP) is proposed. By integrating dynamic-path selection with predictive-wakeup schedule,a sender can predict the wakeup time of available for- warders so that it can avoid relying on sending long preambles to determine the forwarder and trans- mit data. This helps to achieve lower energy consumption and improve delay and reliability of the network in heavy traffic conditions. The MDFP exploits multichannel communication to reduce inter- ference between nodes,so that the reliability of the network in heavy traffic conditions can be further improved. The experiment results on the TelosB testbed showthat,in heavy traffic conditions,com- pared with the state-of-the-art dynamic-path forwarding protocol,the MDFP shows better perform- ance in terms of energy efficiency,delay and reliability.
