Advantages And Disadvantages Of SSA And Static Routing Protocol

The Router protocols implemented will be a OSPF which stands for (open shortest path first). Because of the large network being introduced this protocol will be the most useful. This protocol operates on Internal Gateway Protocols by routing the most direct path and using the bandwidth most optimally. This not only reduces the use of

the routing protocol is simply flooding, S will broadest the data packets and then these data packets are rebroadcasted by every neighbor of S, and

In a figure all ways from S to D incorporate hosts that are outside the request zone. Accordingly, there is no surety that a way can be discovered comprising just of the hosts in a picked request zone. In this manner, if a route is not found inside of a suitable timeout period, our convention Wows S to start another route disclosure with an extended request zone – in our simulations, the extended zone incorporates the whole system space. in this case the inactivity in deciding the route to D be longer.

Its advantages are that its implementation is simple due to the fact that the intermediate nodes only respond to requests and never initiate communication themselves, that it can easily monitor if a node is responsive or not and that it locates data in an efficient way since each node in the network only maintains information for about logN nodes, where N is the number of nodes. Its disadvantages are that it sends queries repeatedly over long distances under certain circumstances because it uses the iterative scheme and that it does not learn useful routing information from received queries like the Kademlia protocol

Though aggregations, CIDR scheme can decrease forwarding tables. The practice of aggregation can still be inhibited by few components. For example a network 208.12.21/24 needs to use the IP address allocated in the same network and the same IP prefix to be used when it needs to modify its service provider. Therefore from the same service provider all networks from 208.12.16/24 to 208.12.31/24 can still be reached, except 208.12.21/24 breaking process of aggregation.

| Given a network topology of two or more routers and an IPv4 addressing scheme, implement static routing and confirm layer 3 connectivity.

In the location-based routing, sensor nodes are distributed randomly in an interesting area. They are positioned mostly by utilizing of Global position system. The distance among the sensor nodes is evaluated by the signal strength obtained from those nodes and coordinates are computed by interchanging information among neighbouring nodes. Location-based routing networks are;

Ranges of Addresses – Class A, Class B and Class C and the private ranges

In this example, here node A wants to send data packets to node D and starts to find the shortest path for its destination, so if node D is a malicious node then it will show that it has active route to the specified destination. It will then send the response In the example, data packets transfer in a hierarchic data center network. The link capacity is 1000 kb/s. The number on each is the traffic load. The distribution of traffic is based on equal cost multi-path (ECMP). In figure 8, we can see that the 3). Congestions

All vehicles transmit a 200-byte safety message at 10Hz with data rate of 6 Mbps. All vehicles attempt to continuously route 64-byte packets at an application rate of 2.048 Kbps to one of 10 other vehicles, selected as sink vehicles. The antenna height AHk of each vehicle is 1.5m. Transmit power is set to 10 dBm and the transmission range for safety message packet delivery is 145 m. For each experiment PCAP trace file per node is enabled. The routing statistics are gathered and compared for each experiment, i-e, with NS2 mobility trace file and with PySNS3. The simulation parameters for performance evaluation of PySNS3 are shown in Table III. In order to calculate packet delivery ratio (PDR), we must count; i) the packets that are actually received, and ii) the transmitted packets that are expected to be received. Both are relative to a specified (circular) coverage area shown in Fig. 6. Let's assume that the transmission range of vehicle A, is in meters, such that TRA > dAB. Where, dAB is distance between A and B, and dBC is the distance between B and

This protocol use Dijkstra algorithm. It maintains a complex data base, also called as link state database, which contains full information about the remote routers and the exact network topology. The goal from this protocol is to provide similar information about network connection to each router, so each router can calculate the best route to each network this is happen when each router generates information about itself and pass these information to other routers in the network so each router make a copy of this information without changing it.

DSDV is a proactive, hop-by-hop distance vector routing protocol where the routing table is maintained by each and every network node. The routing table consists of all the nodes required to reach destination also including the nodes to which packets are not sent. The routing table is kept updated at every time after each entry. In order to avoid the routing loops, DSDV uses the concept of sequence numbers to maintain the originality of route at all times. For the network in figure. 1 below, the routing table for node A can be seen in table. 1 which contains information about all possible paths reachable by node A, along with the next hop, number of hops and sequence number.

In simulated network the source node designated as1 initiates the routing procedure by sending RREQ or Route Request message to its surrounding nodes. The RREQ message sent by the source node is denoted in the color green. The other RREQ messages are shown in cyan, yellow, black etc. The source node 1 is sending the RREQ message to its neighbour nodes 5, 6, 9, 11 and 13 and the links are formed shown by the green line. Every time node 5,6,9,11,13 is sending the RREQ message to its neighbour and the links are formed.

The wired scenario in OMNET++ consists of a reader, tags and central coordinator. The network description file is made up of two areas in a warehouse. The two areas along with the central coordinator forms the network.

A group of wireless sensor nodes (devices) dynamically constructs a temporary network without the exercise of any pre-existing network infrastructure or centralized administration. The main goal of ad-hoc networking is multihop broadcasting in which packets are transferred from source node to destination node through the intermediate nodes (hops). The main function of multi hop WSN is to enable communication between two terminal devices through a bit of middle nodes, which are transferring information from one level to another level. On the foundation of network connectivity, it dynamically gets to determine that which nodes should get included in routing, each node involved in routing transmit the data to further
