Distributed cache updating dynamic source routing protocol ppt

Even though the protocol performs well in static and low-mobility environments, the performance degrades rapidly with increasing mobility. The major difference between this and the other on-demand routing protocols is that it is beacon-less and hence does not require periodic hello packet beacon transmissions, which are used by a node to inform its neighbors of its presence. This algorithm helps to reduce the time in sending and receiving the data. In a reactive on-demand approach such as this, a route is established only when it is required and hence the need to find routes to all other nodes in the network as required by the table-driven approach is eliminated. Thus, all nodes except the destination forward a RouteRequest packet during the route construction phase. Also, considerable routing overhead is involved due to the source-routing mechanism employed in DSR. The connection setup delay is higher than in table-driven protocols. This RouteRequest is flooded throughout the network. The disadvantage of this protocol is that the route maintenance mechanism does not locally repair a broken link. The sequence number on the packet is used to prevent loop formations and to avoid multiple transmissions of the same RouteRequest by an intermediate node that receives it through multiple paths. The erroneous hop will be removed from the node's route cache; all routes containing the hop are truncated at that point. Stale route cache information could also result in inconsistencies during the route reconstruction phase. References[ edit ] It was first described in: Advantages and disadvantages[ edit ] This protocol uses a reactive approach which eliminates the need to periodically flood the network with table update messages which are required in a table-driven approach. In the event of fatal transmission, the Route Maintenance Phase is initiated whereby the Route Error packets are generated at a node. Otherwise, the node will reverse the route based on the route record in the Route Request message header this requires that all links are symmetric. The accumulated path information is cached by nodes processing the route discovery packets. This route cache is also used during the route construction phase. The packet is forwarded only if it is not a duplicate RouteRequest. This may result in high overhead for long paths or large addresses, like IPv6. The intermediate nodes also utilize the route cache information efficiently to reduce the control overhead. Lets have look how the proposed system helps us to eliminate all the above stated drawbacks. Distributed cache updating dynamic source routing protocol ppt



The destination node, on receiving a RouteRequest packet, responds by sending a RouteReply packet back to the source, which carries the route traversed by the RouteRequest packet received. In a reactive on-demand approach such as this, a route is established only when it is required and hence the need to find routes to all other nodes in the network as required by the table-driven approach is eliminated. In the event of fatal transmission, the Route Maintenance Phase is initiated whereby the Route Error packets are generated at a node. Even though the protocol performs well in static and low-mobility environments, the performance degrades rapidly with increasing mobility. Lets have look how the proposed system helps us to eliminate all the above stated drawbacks. Every router will maintain its own cache table and contain the information about its neighboring router. References[ edit ] It was first described in: Each RouteRequest carries a sequence number generated by the source node and the path it has traversed. In this case if failure occurs the data packet have to sent again and this increases the time for receiving and sending of data. In case if any router fails during the transmission of the data the cache algorithm removes this router and routes the information to the destination router through other router in the network. To return the Route Reply, the destination node must have a route to the source node. Thus, all nodes except the destination forward a RouteRequest packet during the route construction phase. This protocol is truly based on source routing whereby all the routing information is maintained continually updated at mobile nodes. The algorithm used contains some modules which are as follows. This may result in high overhead for long paths or large addresses, like IPv6. Nodes can also learn about the neighboring routes traversed by data packets if operated in the promiscuous mode the mode of operation in which a node can receive the packets that are neither broadcast nor addressed to itself.

This routing overhead is directly proportional to the path length. If the route is in the Destination Node's route cache, the route would be used. The sequence number on the packet is used to prevent loop formations and to avoid multiple transmissions of the same RouteRequest by an intermediate node that receives it through multiple paths. The main aim of the project Distributed Cache Updating for Dynamic Source Routing Protocol is eliminating the problem of loss of data packet during the packet are being transmitted from the router by using the protocol. A destination node, after receiving the first RouteRequest packet, replies to the source node through the reverse path the RouteRequest packet had traversed. This route cache is also used during the route construction phase. To return the Route Reply, the destination node must have a route to the source node. The disadvantage of this protocol is that the route maintenance mechanism does not locally repair a broken link. Nodes can also learn about the neighboring routes traversed by data packets if operated in the promiscuous mode the mode of operation in which a node can receive the packets that are neither broadcast nor addressed to itself. Again, the Route Discovery Phase is initiated to determine the most viable route. The packet is forwarded only if it is not a duplicate RouteRequest. The destination node, on receiving a RouteRequest packet, responds by sending a RouteReply packet back to the source, which carries the route traversed by the RouteRequest packet received. Restricting bandwidth[ edit ] Dynamic source routing protocol DSR is an on-demand protocol designed to restrict the bandwidth consumed by control packets in ad hoc wireless networks by eliminating the periodic table-update messages required in the table-driven approach. This protocol is truly based on source routing whereby all the routing information is maintained continually updated at mobile nodes. References[ edit ] It was first described in: This table will contain all the information regarding the routers through which the packet will travel through will sending and receiving the information. The major difference between this and the other on-demand routing protocols is that it is beacon-less and hence does not require periodic hello packet beacon transmissions, which are used by a node to inform its neighbors of its presence. The erroneous hop will be removed from the node's route cache; all routes containing the hop are truncated at that point. The intermediate nodes also utilize the route cache information efficiently to reduce the control overhead. It has only two major phases, which are Route Discovery and Route Maintenance. To avoid using source routing, DSR optionally defines a flow id option that allows packets to be forwarded on a hop-by-hop basis. Consider a source node that does not have a route to the destination. Even though the protocol performs well in static and low-mobility environments, the performance degrades rapidly with increasing mobility.
