Hierarchical addressing scheme for 6LoWPAN WSN
- 101 Downloads
This paper proposes a hierarchical addressing scheme for 6LoWPAN WSN and aims to reduce the addressing cost and latency. The proposed scheme includes the address initialization and address maintenance algorithms. When the network starts, the address initialization algorithm is performed. Through the address initialization process, each node can be configured with a globally unique address without duplication address detection. The address maintenance algorithm is made up of the address configuration sub-algorithm and the address reclamation sub-algorithm. After the address initialization process ends, a new node performs the address configuration sub-algorithm to obtain a globally unique address from a neighbor. The address reclamation sub-algorithm is performed to reclaim the released addresses for reuse so that there is enough address resources available for assignment. Finally, the proposed scheme is evaluated, and the results show that this scheme effectively reduces the addressing delay and cost.
