In this paper, a robust and efficient delay tolerant and quality of service (QoS) oriented data gathering protocol for low power lossy wireless sensor network (WSN) has been proposed. Our proposed routing protocol applied received signal strength based forwarding node selection and transmission path formation scheme, which has been further armoured with multiple timer based handoff optimisation to enable optimal data transmission, particularly data gathering using single mobile sink node. To ensure backward compatibility of RPL, our proposed scheme has incorporated control message modification that makes our proposed routing protocol applicable for major low power lossy network commonly known as RPL based internet of things (IoT) ecosystem. The higher packet delivery ratio of 98.93% and lower delay and control packet requirements make our proposed routing protocol computationally efficient to be used for major WSN based IoT communication systems.
