Abstract

Duplicate Detectable Opportunistic Forwarding in Duty-Cycled Wireless Sensor Network

Duplicate Detectable Opportunistic Forwarding in Duty-Cycled Wireless Sensor Network routing, offering relatively efficient and adaptive forwarding in low-duty cycled sensor networks, generally allows multiple nodes to forward the same packet simultaneously, especially in intensive traffic networks. 
 
DOF enables senders to obtain information from all potential forwarders via a slotted acknowledgement scheme so that the data packets can be sent to the next-hop forwarder. DOF explores the possibilities as many as possible based on light-weight coordination and removes duplicate packets from the forwarding process. 
 
On an indoor test bed with 20 TelosB nodes, we implement DOF and evaluate its performance. The experimental results show that DOF reduces the average duplicate ratio by 90% compared to state-of-the-art opportunistic protocols and achieves a 61.5% increase in network yield and a 51.4% reduction in energy consumption.

 

Conclusion

In this paper, we propose DOF, a duplicate-detectable, non-synchronized, low-power opportunistic forwarding that adapts to various traffic loads. Based on the slotted acknowledgment, DOF mainly solves the problem of channel degradation incurred by the large amount of duplicates in traditional opportunistic forwarding and retains as much as possible the advantages of opportunistic routing. The test bed experiments show DOF is more efficient and reliable than the state-of – the-art low-duty cycled forwarding protocols.

Building a versatile and proficient sending convention is earnest for a dutycycled wireless sensor network. We propose DOF in this work, a perceivable copy astute sending that is versatile with different loads of activity. In view of the affirmation, DOF mainly takes care of the channel debasement issue caused by the extensive measure of copies in customary deft sending and holds the advantages of sharp steering however much as could be expected.
