Investigation and Designing for Network Congestion Detection and Prevention in DTN

Nowadays higher demands of lightweight mobile devices for monitoring critical situation such as weather, tsunami, earth quick and rural area where direct communication not possible. Those area DTN mobile communications play important role to provide message exchange between devices through limited capacity (channel, memory, processing). Due to exhaustive demand of DTN mobile communication, concurrently multiple nodes exchange the message from one location to another through lightweight capable node that arises the problem of congestion, in this paper investigate various existing approach to resolve the network related issue to enhance the performance of delay tolerant network (DTN). Those existing approach give the roadmap to further enhancement of DTN network for smooth working in real time communication in rural area where disseminated connectivity. In the paper we also design new congestion detection and prevention method using collaborative methodologies such as input and output dependency retrieval, energy utilization and fuzzy rule definition and provide lightweight solution to the DTN for improving the efficiency of network where nodes are configure in limited capacity. In future we analyse those work through the network simulator −2 and measure the performance of the network.
