Enhancing performance using TOHIP in MANET
Abstract— Mobile Ad hoc Network (MANET) is a special self-describing wireless ad hoc network which consists of additional number of nodes that can move randomly and erratically. Due to this infrastructure it enables numerous kinds of attacks and establish topology-exposure problem. Many of the existing multipath protocols may ignore the topology-exposure problem. In this, we proposed a TOpology-HIding multipath routing Protocol (TOHIP) for preventing attacks in topology-exposure. In TOHIP, the link connection information is hidden in route messages, so that the malicious nodes cannot conclude the network topology. In Route Reply phase, the protocol TOHIP can also be used to establish multiple node-disjoint routes and eliminate the unreliable route before transmitting packets in Route Probe phase. With facilitate of a newly designed protocol, security was assured and earned superior capability of finding routes in MANET. The simulation result shows that TOHIP has given recovered performance when compared with Ad hoc On-demand Multipath Distance Vector (AOMDV) routing protocol.
