Enhancing 6LoWPAN Schemes to Support Priority Driven Routing

Internet of Things(IoT) has become an emerging area of research. 6LoWPAN is introduced to connect large number of things which are nothing but sensors of different capabilities. In 6LoWPAN, there are mainly two routing schemes, named as route-over (assembly mode) and mesh-under (direct mode), based on which layer is involved during routing decisions. Modified route over comprises the advantages of both schemes. This paper presents a scheme that provides efficient routing in terms of priority by adaptive retry mechanism and hassle free route. Results of the scheme have been taken on the basis of performance metrics, such as average round-trip time, end to end delay and packet loss. Event-driven operating system, TinyOS, is used to develop the proposed scheme.
