A proxy-based Passive Duplicate Address Detection protocol for IPv6 wireless sensor networks
Dana Blouin, Steven Gordon · 2015
IPv6 addressing schemes for networks consisting of power constrained wireless sensor nodes require special consideration to reduce the time and traffic required for a node to join the network. Here we explore several existing models of IPv6 address allocation schemes for this use case. We offer a novel approach to reduce the chance of address duplication via a hierarchical manipulation of the host portion of the IPv6 address space, which represents each segment of the network leaving nodes a large segment of address space to generate a unique identifier portion. Overhead is further reduced though the application of a Passive Duplicate Address Detection scheme, which allows nodes to configure an address but postpone duplication check until traffic traverses the network and is sent out through the gateway.
