Adaptive opportunistic routing over DTMANETS: Proposals and issues

Abstract

The convenience of small, cheep, and mobile communication devices such as laptops, cell phones, handheld devices, and mobiles sensor nodes, has popularized mobile ad hoc networks (MANETs). With the convenience, interconnection among these devices introduced new dimensions of challenges for the technology to be used for communication. Such challenges include wireless communication, mobility, and portability. Furthermore, the sparse behavior of nodes in turbulent areas, where connectivity is commonly not possible all the time, resulted in yet another exciting technology known as delay tolerant networks (DTNs). This work is related to the association of opportunistic techniques with different scenarios in which different opportunistic elements of relay nodes, e.g. message storage capacity, territory and velocity are classified according to its usefulness in a given scenario.
