Abstract

To circumvent the degraded goodput, high latency and low resource utilisation efficiency of conventional transportlayer protocols in the Internet of Things, a novel permutationbased encapsulation scheme is proposed for seamless delivery of packets to achieve high goodput and low latency. In this scheme, extra application-layer data is delivered by our permutationbased data unit (PBDU), which is mapped onto the permutation associated with a legitimate tuple of various packet-lengths in a group. Therefore, the network interface throughput is substantially improved for a given number of resource units in the physical channel. The optimal design of this encapsulation is expressed in closed form to maximise the PBDU size, allowing us
to quantify the attainable improvements of goodput and latency. In addition, the proposed scheme achieves higher physical-layer throughput and secrecy rate than conventional encapsulation.
