LoWPAN: Efficient Routing Discovery Process for Wireless Sensor Networks (WSNs)

This paper introduces efficient routing discovery process based on 6LoWPAN for wireless sensor networks. This approach is performed in the link layer in order to route the data frame through intermediate sensor nodes without processing the headers in the upper layers. As a result, the routing cost is reduced and the routing efficiency is improved. Further, in the approach, a source node creates multiple separate routing paths using routing discovery process. When one routing path fails, another routing path is randomly selected to work without routing discovery process. This approach also uses the routing path repair algorithm that helps the intermediate node to determine, if the next hop is inaccessible, then it repairs the corresponding routing path to guarantee that the data are correctly routed to the destination node. The performance parameters of the proposed scheme are analysed. The simulation results demonstrate that this approach can decrease the routing cost and curtail the routing delay efficiently.
