We have frequently referred to the routing algorithm as the network layer. It uses the hop count as metric in route selection. Routing algorithms an overview sciencedirect topics. Learning the optimally coordinated routes from the statistical. Routing algorithms can be distinguished by the way their two main operations are performed. Unicast routing protocols for wireless ad hoc networks. The routing algorithm selects the single receiver from the group based on which is the nearest according to some distance measure. Here, we will describe the routing algorithms that are studied in the present work. In practice for example, with the internets ospf routing protocol. A simple internetwork where h represents hosts and r represents routers. A metric is a standard of measurementfor example, path lengththat is used by routing algorithms to determine the optimal path to a destination. This model was developed by the resilinets research group at the university of kansas. The different optimization techniques are ant, bee, ant bee, ant ga, ant pso, ga, pso, ant dijkstra are the combinations used in the packet delivery. To be able to exchange any information about the network, some entity needs to collect data related to the metrics used in the routing algorithm.
For example, suppose that there is a street with 200 m length. In this example, the time required for the broadcast packet to reach all nodes is the. Routing protocols routing protocol protocol to exchange of information between routers about the current state of the network routing protocol jobs create routing table entries keep routing table uptodate compute the best choice for the next hop router. Dsdv routing destinationsequenced distance vector dsdv routing protocol is a proactive, tabledriven routing protocol for manets developed by charles e. Routing algorithm classification a linkstate routing algorithm. This algorithm, for example, can be used to route queries to nodes that have a camera, and enough energy to use it. Vehicular adhoc networks, routing protocol, positionbased routing, learning automata. Routing is the process of selecting a path for traffic in a network or between or across multiple. Traditional routing algorithms are likely to be inefficient due to slow convergence times e.
Linkstate ls routing algorithm dijkstras algorithm topology and link costs known to all nodes accomplished via link state broadcast all nodes have same info computes least cost paths from one node source to all other nodes gives forwarding table for that node iterative. Cisco routers, for example, attribute a value known as the administrative distance to each. Routing in packet networks shortest path algorithms. Routing all addresses are globally known no connection setup host sends packet with destination address in header no path state. A highly adaptive distributed routing algorithm for.
