Label-Based Addressing Scheme for Hierarchical Wireless Sensor Networks

The traditional address-based addressing scheme cannot satisfy the addressing requirement of large-scale and business-centric wireless sensor networks (WSN). To solve this problem, a new hierarchical structure applicable to the large-scale heterogeneous WSN is proposed. Based on the structure, a label-based addressing (LBA) scheme is proposed as well. The proposed scheme different business types into the lables and marks the operated data. By creating a mapping between labels and node IP addresses, a user is able to query any business data through its label. The simulation demonstrates that LBA scheme is outperforms the traditional address-based and other content-based addressing schemes in terms of data request response time and packet delivery.
