Dynamic search technique used for improving passive source routing protocol in MANET

Mobile Adhoc Network are dynamically configurable and organized network, without any existing infrastructure. It is an integration of numerous wireless nodes. To communicate between the nodes efficiently, A routing protocol builds the route efficiently between the nodes within a network. The routing algorithm should dynamic discover a route; effectively maintain the route with minimum overhead and bandwidth. Our work proposes a novel Passive Source Routing protocol that has a very small communication overhead. The proposed work enhances light-weight passive source routing protocol for MANETs, To enhance the PSR, we use Dynamic search algorithms namely DSF, DSRW and Knowledge Based - DS to discover the route. In such method, every node of the wireless network contains a neighbor table. Such table contains each node and its neighbors with distance between them. Therefore, each node has a full topology of the wireless network which is useful to discover the route. Periodic information exchange is used to update such table. The solution of routing are analysed in MANET and performance are evaluate using NS-2 simulator with various network paramters.
