“…Consequently, the FWD strategy brings a potential efficiency gain given tolerance of delivery delay. In [10], the FWD strategy is adopted in a scenario where sensors send data to a mobile sink moving according to a predefined trajectory. The feasibility of the FWD strategy is further investigated in [12] on the basis of directional movement with randomness.…”

Further accelerated by the Internet of Things (IoT) concept, various devices are being continuously introduced into diverse application scenarios. To achieve unattended updates of IoT smart object(s), there remains a challenging problem concerning how to efficiently deliver messages to specific groups of target nodes, especially considering node mobility. In this paper, the relay selection problem is investigated on the basis of directional movement with randomness (e.g. typically associated with the searching or migrating behaviour of animals). Unlike numerous works tackling one-to-one communication, we focus on efficient group delivery (one-to-many). A two-level delay budget model is considered to reflect the flexibility of delay tolerance, which brings potential efficiency gains for group delivery compared with using a single budget boundary. Following the description of the system model, a combinatorial bi-objective optimisation problem is formulated and solutions are proposed. Simulation results show that the greedy algorithm can achieve comparable performance to an evolutionary algorithm when the delivery satisfaction outweighs efficiency. Furthermore, we show that our proposed greedy scheme can outperform the state-of-theart when the delivery efficiency becomes increasingly important.

“…Based on knowledge of vehicular navigation, delay-tolerant delivery has been utilised to reduce forwarding hops in the literature such as [10] and [11]. Nevertheless, the exact movement trajectory of mobile nodes can hardly be known in advance with regard to some IoT scenarios (e.g.…”

“…In literature, a Forward-Wait-Deliver (FWD) strategy has been adopted (such as [9]- [11]) to facilitate energy-efficient dissemination of delay-tolerant information. Instead of immediate delivery to the mobile destination, packets are forwarded to a relay 1 in advance, waiting for later delivery when the destination node is directly contactable.…”

“…For the Type-IV class, a maximum (or average) movement speed is estimated for the mobile node, so a circular movement range can be drawn to predict contact (as in [17] [18]), where the radius depends on the delay since the location report. For the Type-V class, with additional knowledge on movement direction, the location of future contact can be expected given the delay (such as in [19] [9]). However, the speed and direction are not enough to differentiate heterogeneous mobility, which limits the contact prediction based on the Type-IV/V mobility description.…”

As a promising use-case of the Internet of Things (IoT), wildlife tracking and monitoring applications greatly benefit the ecology-related research both commercially and scientifically. In literature, a Forward-Wait-Deliver strategy has been researched to facilitate energy-efficient dissemination of delaytolerant information, which penitentially contributes to long-term tracking and monitoring. However, this strategy is not directly applicable for wildlife tracking and monitoring applications, as the movement trajectory of animals cannot be precisely predicted for relay selection. To this end, further studies are required to utilise partially predictable mobility based on more generalised navigational information such as the movement direction. In this paper, the feasible exploitation of directional movement in pathunconstrained mobility is investigated for strategic forwarding. Our proposal is an advance to the state-of-the-art because the directional correlation of destination movement is considered to dynamically exploit the node mobility for the optimal selection of a stationary relay. Simulation results show that higher delivery utility can be achieved by the proposed fuzzy path model compared with a forwarding scheme without contact prediction or one based on linear trajectory model.
