Route discovery by farthest intermediate link distance reliability cost based for MANETs through cross layer approach

Mr. P.A. Abdul Saleem, Dr. Naveen Kumar

MANETs are self-configuring network of mobile routers and associated hosts connected by wireless links, the union of which form an arbitrary topology. The routers are free to move randomly and organize themselves arbitrarily, thus the network wireless topology may change rapidly and unpredictably. MANETs may also be defined as a network formed without any central administration which consists of mobile nodes that use a wireless interface to send packet data or MANET is a collection of mobile nodes with no fixed infrastructure, where some intermediate nodes should participate in forwarding data packets. MANETs have attracted a lot of researchers [1], [2] because of the growing popularity of mobile computing devices. The integration of mobile ad-hoc networks (MANETs) with the Internet and infrastructure based wireless networks have become an essential part of ubiquitous networking and has drawn the attention of researchers from industry and the networking community. Research on cross layer design in adhoc networks has recently attracted in significant interest [3], [4]. Initially, MANETs scenarios are deployed at places like business associates sharing information during meeting, military personnel coordinate emergency effort„s relief personnel coordinating efforts after a natural disaster such as hurricane, earthquake or flooding. Today, MANETs are required to support increasing demand for multimedia communication. The proposed research scheme FILDRC improves the end to end delay, throughput and also reduces the overhead to some limit. Traditional protocol selects the route with the smallest hop count. This can be implemented in military environment. It is observed that when load density is low, the link distance should be short; otherwise the link distance is large. Link distance is adjusted according to the network load. In this research paper we are concentrating mainly link distance on networks, end-to-end delay, and throughput in multi hop wireless networks.
