Abstract—A Wireless Sensor Network is formed of small devices with the capability of detecting nearby physical characteristics and sending them hop by hop to the destination nodes by means of low power and short range wireless transmissions. The lifetime of a Wireless Sensor Network primarily relies on the efficiency of the routing protocols. The nodes which lie on the perimeter of the parent node face the issue of packet loss due to the disturbance created by the surrounding devices operating on the same radio band, such as Wi-Fi, Bluetooth, and other 802.15.4 devices. The nodes present on the edge of a network have a packet delivery ratio much lower than the average packet delivery ratio of the whole network. As a result, much research has been carried out on improvement of the packet deliver ratio of the nodes on the edge of the network. In this paper, we propose an efficient routing protocol for low-power and lossy networks in Contiki based on evaluations of the packet delivery ratio and the throughput. Experimental results show that the proposed routing protocol performs better than the baseline models, with a very efficient
