Book Description
"Opportunistic networking is employed in scenarios where end-to-end communication paths between nodes cannot be assumed due to continuously changing network topology. In these networks, data is routed in a "store-carry-forward" fashion by exploiting the transient communication opportunities that arise when mobile nodes equipped with short-range wireless interfaces come within each other's transmission range. Designing efficient routing schemes for opportunistic networks is challenging as they face a trade-off between delivery performance and resource consumption. In this thesis, we propose a novel opportunistic routing algorithm that addresses this trade-off by incorporating information about the node contact pattern in the network. Aggregating contact events into a weighted graph enables us to detect communities and learn about the neighbourhoods of nodes. This information is utilized by our algorithm to assess the usefulness of every forwarding opportunity that arises. Performance evaluation of the proposed algorithm shows that it is capable of achieving good delivery performance while consuming significantly fewer resources in comparison to the existing opportunistic routing algorithms." --

Book Description
Routing in sparse networks results in relatively long packet delivery delays and is unreliable. Thus, sparse networks are not an appropriate networking solutions for applications in which delay delivery is of critical importance. However, some applications can tolerate substantial amount of delay. Networks which can support communication for such applications are referred to as the Delay-Tolerant Networks (DTNs). Epidemic Routing Protocol (ERP) has been proposed and widely used for routing in DTNs. ERP is based on the concept of packet flooding - a node that carries a packet transmits (i.e., replicates) the packet to every node that it encounters. Thus, the numbers of copies of the packet rapidly increases. This type of routing results in the shortest possible packet delivery delay and in high packet delivery probability. However, these results come with strict assumptions that the network nodes have sufficiently large amount of energy and storage. In case where the network sequentially routes multiple packets, increasing the number of copies of the packet has its disadvantages. First is the excessive amount of energy used for transmissions. When nodes have limited amount of battery energy, increased number of copies eventually results in faster depletion of the batteries of the network nodes, reduction in the number of active nodes, and in reduced network lifetime. Second is the amount of memory used for packet storage. A node is likely to receive many different packets which will pile up the memory before the node encounters the sink. When its memory is full, the node should either remove a packet from its memory, or not receive another packet. Either way, this results in less packet copies and decrease of packet delivery probability. This study analyzes the ERP for two different cases and shows how to overcome the disadvantages by modifying the ERP. In case when the nodes have limited battery energy, minimizing and equalizing the energy expenditure at the nodes efficiently increases the network lifetime. In case when the nodes have limited storage, using linear combinations of multiple packets increase the packet delivery probability without any major cost of energy or storage.

Book Description
The opportunistic network is an emerging and recent area of research. To make this research area more adaptable for practical and industrial use, there is a need to further investigate several research challenges in all aspects of opportunistic networks. Therefore, Opportunistic Networks: Fundamentals, Applications and Emerging Trends provides theoretical, algorithmic, simulation, and implementation-based research developments related to fundamentals, applications, and emerging research trends in opportunistic networks. The book follows a theoretical approach to describe fundamentals to beginners and incorporates a practical approach depicting the implementation of real-life applications to intermediate and advanced readers. This book is beneficial for academicians, researchers, developers, and engineers who work in or are interested in the fields related to opportunistic networks, delay tolerant networks, and intermittently connected ad hoc networks. This book also serves as a reference book for graduate and postgraduate courses in computer science, computer engineering, and information technology streams.
