MERLIN: Cross-layer integration of MAC and routing for low duty-cycle sensor networks
Sensor network MAC protocols typically sacrifice packet latency to achieve energy efficiency. Such delays may well increase due to routing protocol operation. For this reason it i...

A metric for routing in delay-sensitive wireless sensor networks
Abstract--We present a new scheme to reduce the end-toend routing delay in the mission-critical applications of the wireless sensor networks (WSNs) under the duty cycle model. Whil...
