AMR6: Advanced multicast routing for 6LoWPAN

Internet of Things(IoT) has emerged as the most promising technology to shape every sphere of life. 6LoWPAN is introduced to connect large number of things which are nothing but sensors of different capabilities. 6LoWPAN incorporates an adaptation layer to enable transmission of IPv6 packets. This layer performs compression of huge IPv6 packets for transmission in low powered networks and controls routing decisions in the network layer. In this paper, a scheme is proposed for multicast scenarios that gives an advanced re-transmission control by providing identification to individual fragments and reducing the number of re-transmission requests by aggregating the requests. Performance of the scheme is measured on the basis of metrics, such as average round-trip time, end to end delay and packet loss(%). The proposed scheme has been developed using TinyOS, an event-driven operating system designed for wireless sensor network and nesC.
