A Review of Multipath Routing protocols for AD-HOC network”

Digital communication

ad hoc networks contain a collection of wireless nodes which communicate among themselves without the exigency of fixed infrastructure. Limited transmittal span of wireless network nodes causes multiple hops to share information with any other node in the network. The main function of Mobile Ad Hoc networks is to find and establish the route between source nodes and destination node, and forwards the traffic from source node to neighbour node to reach destination when the transmission range exceeds. The major issue in Mobile Ad-hoc networks (MANET) is maintaining the topological information in the network. An ad-hoc network has certain characteristics, which imposes new demands on the routing protocol. The most important characteristic is the dynamic topology, which is a consequence of node mobility. Nodes can change position quite frequently, which means that we need a routing protocol that quickly adapts to topology changes .Many routing protocols are available in Mobile Ad-hoc networks.
