ABSTRACT
An Opportunistic mobile networks (OMN) considers almost all of the wireless network's peculiarities, like mobility of the user, ad hoc node connections and links, frequent disconnections, network partitions, and link instability, which have to date been dealt with in the wireless network scenario as "exceptions." These peculiarities require specialized routing protocols, and energy management techniques. Energy efficiency in the implementation of routing protocols for mobile ad hoc networks is much needed to prolong the operational time of the network. OppNets can be formed using user mobility when there is a potentially exploitable regularity in patterns. The chapter outlines some of the methodologies based on the following factors that are used to leverage the characteristics of nodes and their connections. They are Frequency at which the nodes are encountered, Strength of social relationships that exist between the users, Places regularly visited, Type of content they are interested in and intelligent infrastructure.
