Delay Tolerant

Many applications of Internet of Things (IoT) have been implemented based on unreliable wireless or mobile networks like the delay tolerant network (DTN). Therefore, it is an important issue for IoT applications to achieve efficient data transmission in DTN. In order to improve delivery rate and optimize delivery delay with low overhead in DTN for IoT applications, we propose a new routing protocol, called Scheduling-Probabilistic Routing Protocol using History of Encounters and Transitivity (PROPHET). In this protocol, we calculate the delivery predictability according to the encountering frequency among nodes. Two scheduling mechanisms are proposed to extend the traditional PROPHET protocol and improve performance in both storage and transmission in DTN. In order to evaluate the proposed routing protocol, we perform simulations and compare it with other routing protocols in an Opportunistic Network Environment (ONE) simulator. The results demonstrate that the proposed Scheduling-PROPHET can achieve better performances in several key aspects compared with the existing protocols.

In Delay tolerant network having intermittent connectivity so there is no guarantee of finding a complete communication path that connecting the source and destination. There no any end to end connectivity for delay-tolerant network selection of routing protocol is important to deliver the message in an efficient way and increases chance to deliver a message to the destination. Some existing routing protocols improve the delivery ratio but it also increases the overhead. Our paper proposed Contact History Based Routing (CHBR) that use Neighborhood Index and Time varying properties such as temporal distance, Temporal Diameter and centrality for benchmarking the existing routing protocol. First, temporal metrics are evaluated for synthetic and real trace data. Then CHBR protocol is compared with the Epidemic and PROPHET for delivery ratio, overhead and the number of messages dropped. This has been carried using Opportunistic Network Environment simulator under real and synthetic datasets.

The main applications of delay tolerant network lie in space research, military, tactical and other security sensitive operations. In these and other applications, secure and energy efficient routing is an important issue in homogeneous and heterogeneous network. This chapter contributes a research work that demonstrates the design, simulation, testing and evaluation of secure, energy efficient and environment independent routing protocol for delay tolerant network. The proposed protocol not only proposed secure approach but also energy efficient approach in homogeneous and heterogeneous environment. The proposed approach utilize sectorization technique to achieve its goals of security, energy efficiency and environment independence. Described in this chapter is a detailed architecture, design, simulation, testing and evaluation of the proposed protocol. Having evaluated these protocols in various simulators, it is concluded that the proposed routing protocol utilized minimum energy and bandwidth and also provided secure transmission.
