Internet of things (IoT) is internetwork of objects, embedded with Hardware and computing software. The heterogeneity in IoT circumstance makes routing a challenging process. In IoT, some devices are connected directly to the internet and some devices connected to internet through gateway. The gateway acts as a bridge between IP Networks and Low Power Lossy Networks (LLN). RPL and LOADng are two major routing protocols used in 6LoWPAN for IoT applications. CALDUEL is a routing technique enhanced from loading protocol to minimize the Route Discovery Overhead. The proposed work is to enhance CALDUEL technique to increase throughput and packet delivery ratio. The proposed work is analyzed using different network scenarios.
