Popis: Long identifier brings low packet forwarding efficiency in Internet of Things (IoT), whereas short identifier may suffer from the exhaustion of identifier space. Compared with fixed-length identifiers ( e.g. , IPv4 and IPv6), flexible identifiers are expected for balancing the packet processing efficiency with the various IoT scales. However, it is challenging to make IoT support the flexible identifier-based forwarding. In this letter, we firstly proposed a novel variable-length identifier (VLI) solution for interconnecting IoT networks. In particular, a VLI datagram header is designed to effectively support a flexible identifier field. Following a basic VLI header, one (multiple) extension header(s) can be added if require. Each extension header includes a fixed-size identifier field. According to the combination of multiple identifier fields, the variable-length identifier can be easily achieved, resolved and supported by the IoT nodes in a flexible way. Experimental results show that VLI can decrease the processing delay effectively.
