Efficient forwarding strategy in HDRP protocol based Internet of Things

Abstract

The Internet of Things (IoT) includes a variety of heterogeneous wireless network technologies such as Delay Tolerant Networks (DTN) and all kinds of smart devices connected over a wireless network. The strong size and cost constraints of DTN nodes lead to corresponding constraints on resources such as energy, memory, communication speed and bandwidth, which in turn limits the contact between DTN nodes. DTN has emerged as a promising new network paradigm that aims to cope with the increasing number of heterogeneous networks and the need for efficient and robust data dissemination to be more stable. But one of the hindering bottlenecks the full applicability of such a DTN-based approach to the IoT, is that forwarding data in an environment could lose when the connection between nodes is intermittent. In this paper, we propose an effective bundle forwarding strategy for the IoT environment in which we control the number of bundle replications to balance energy consumption on the network. Simulation results demonstrate that the proposed solution performs better than other methods in terms of delivery delay and delivery rate (roughly 18% improvement).
