A survey on routing methodologies for ICMANET

Mobile Ad hoc Networks were well - thought - out as the independent deployment of mobile nodes. It is eminently said that MANET is a self configuring infra - structure less network that do not count on centralized and organized connectivity of mobile nodes. Military networks, Disaster relief efforts are some common instance of Mobile Ad hoc Networks. MANET showed the way for a new form of network namely Intermittently Connected Mobile Ad hoc Network (ICMANET) which is prominently a Delay Tolerant Network. MANET leads to ICMANET due to sparse or high mobility in the networks. The significance of such networks is that they don´t ever hold a complete end-to-end connectivity between nodes. Exemplary examples of intermittent network includes Wildlife Management, Military Surveillance etc. Enormous research works attest massive possible methodologies for efficiently forwarding packets between nodes. The routing methodologies indict mostly the traditional routing protocols akin to AODV, DSR. The exigent factor of ICMANET is to route packets where such traditional protocols do not overlay a resourceful forwarding of data packets. In this paper, we put forward a survey of prevailing routing paradigms that explore techniques for routing along with virtues and shortcomings.
