In this paper, we propose a comprehensive analysis of latencies and power consumption of unicast and multicast communication patterns in single-hop duty cycled 6LoWPAN networks. Simulation and testbed experiments are realised under different Radio Duty Cycling (RDC) protocols, channel checking rates and packet fragmentation. The findings of this study(More)
Wireless Sensor Networks (WSNs) have been recognized as a key technology in shaping tomorrow's world. To assure reliable and cost-effective forwarding of data, opportunistic schemes were explored. In this paper, we evaluate the performance of delay-based opportunistic schemes in WSNs and then propose a mechanism to overcome their drawbacks. The proposed(More)
