Next generation networks will certainly face requesting access from different parts of the network. The heterogeneity of communication and application software's changing situations in the environment, from the users, the operators, the business requirements as well as the technologies. Users will be more and more mobile, protocols, etc. will increase and render the network more complex to manage. Opportunistic communication has emerged as a new communication paradigm to cope with these problems. Opportunistic networks exploits the variation of channel conditions, provides an additional degree of freedom in the time domain and increase network performance.
