As children, many of us were glued to the science fiction stories in comic books or television
shows. Arguably, computer-generated imagery (CGI) in the recent sci-fi shows or movies …

Delay tolerant networks (DTNs) are widely adopted to many network applications, such as
disaster recovery and battlefield communications. Such critical network scenarios call for an …

A Delay Tolerant Network (DTN) is prone to security threats, especially the Selfish and Black-
hole attacks. In this work, we have taken up these two security issues in a DTN based on an …

Delay tolerant network (DTN) is developed for sparse wireless networks with intermittent
connectivity. The low-cost, customized hardware components in DTN nodes leave them …

The delay-tolerant networks (DTNs) are mainly characterized by decentralized and self-
managed structures possessing unique features and characteristics. However, limited …

In Delay Tolerant Networks (DTNs), routing protocols work in an environment where there is
no guarantee of end to end path between source and destination. Mobility of nodes is an …

Delay tolerant networks (DTNs) are resource-constrained networks where messages are
relayed in a store–carry–forward fashion. In most routing protocols of DTNs, each node is …

In opportunistic networks, the nodes connect to each other wirelessly and use the store-carry-
forward technique to transmit the data from one node to another node. Opportunistic …

Maintaining user connectivity over heteroge-neous wireless networks will be a necessity
with the wide spread of wireless networks and limited geographic coverage and capacity of …

Blackhole attack is one of the major security concerns in mobile ad-hoc networks that are
hard to detect. In this type of attack, the malicious node attracts message packets by …
