Delay Tolerant Networks (DTN) comprise nodes with small and limited resources, such as power and storage space. The constraint of resources, together with the mobility and sparsity of DTN nodes, trigger an intermittent connection among the nodes and require delay tolerance of their applications. In such a challenging environment, decentralized routing protocols are implemented with the main concern...
In metropolitan-area mobile adhoc networks (M-MANET), such as in vehicular networks, nodes are not connected continuously. Some nodes are power limited, such as smartphones and laptops, and some nodes have high mobility. This harsh environment imposes networking challenges among the nodes. Routing is one of the critical networking problems that needs to be resolved. Using inexact and only locally...
