Wireless Network Routing Protocol Analysis
In Wireless networks nodes send information from one point to another by using electromagnetic waves without relying on any physical connection. The main benefit of mobile wireless networks is access to the application from anywhere and at anytime. The wireless network is preferred because the cost of wired network is expensive due to the high cost of Ethernet cables, hubs and switches. Wireless networks based on IEEE 802.11 allow seamless access to organization network. The most widely used wireless standard is IEEE 802.11b which is a moderate-range, moderate-speed technology. It extends throughput up to 11Mbps using the same 2.4GHz as IEEE 802.11. …show more content…
AODV allows mobile nodes to respond to the breakage of links and changes in network topology. The main feature of AODV is it uses destination sequence number for each route entry, and that sequence number is created by the destination. The messages defined by AODV are Route Requests (RREQs), Route Replies (RREPs) and Route Errors (RERRs). When a node requires a route to the destination then that node broadcasts a RREQ to the destination in order to find the route. A route is made available by unicasting a RREP back to the source. Nodes check the link status of neighbour nodes , if the link breaks then the node will use RERR message to send notifications to other nodes to indicate the loss of …show more content…
According to that, TCP Vegas is better than other TCP implementations in terms of sending data and information. Simulation, implementation concludes that TCP Vegas provide higher throughput than compare to other TCP implementations. Sack is fair to Reno and it is competing with Vegas, and finally Vegas easily adapts to the changing bandwidth.
Hala A. ElAarag and Mostafa A. Bassiouni[5], published paper on “Transport Control Protocol for Wireless Connections”, in that comparison of TCP Reno, New Reno and Sack is done. Here network topology consists of three nodes: a fixed host, a base station and the mobile host, and evaluated throughput, packet delay and transfer time. TCP Reno shows high throughput, least transfer time and less packet delay than

Application – this layer is specific to applications and provides services such as email, network software services and file transfers Presentation - In this layer, the data is formatted in a schema that network understands, and also manages data encryption and decryption Session – this layer establishes and controls the data communication between

971 Words | 4 PagesI am going to explain the current methods and protocols we use in a LAN environment to provide a high level of redundancy, such as EtherChannel, FHRP (First Hop Redundancy Protocols) and STP (Spanning Tree protocols). I will briefly explain how the protocols work & then discusses the latest implementations of the protocol and the environment you would expect to see them working in. The STP is a protocol that prevents loops from occurring in a switched LAN environments when a device has multiple interconnected paths. The protocols works by sending BDPU messages across in the interconnected devices, detects the loop then removes it from the topology by shutting down the port.

Another new aspect is challenger module will only allow one client to securely communicate with the server so communication architecture is peer to peer only but multiple clients can try to connect, so they will be connected to server but will not be authenticated to start messaging they have to wait for authenticated communication clearance one by one. Here the flow diagrams are described in two parts –First in Fig. 1 the generic communication model and in Fig.
Nt1330 Unit 1 Review Paper
572 Words | 3 PagesNetwork monitoring now is limited because of the number of servers it takes to deal with the large influx of router data. Router manufacturers have been attempting to combat this by adding counters to the routers that report on the number of data packets a router has processed during some time interval, but adding counters for every special task would be impractical and put more stress on servers since they would need thousands more to process the flood of data coming in. To combat this a system called Marple was created by researchers at MIT, Cisco Systems, and Barefoot Networks(Hardesty). Marple involves a programming language the allows network operators to specify a wide range of network-monitoring tasks and a small set of simple circuit elements that can execute any function specified in the language.

710 Words | 3 PagesFinally, the client sends a ACK packet back to the server, acknowledging the connection has been established. This sets up a full duplex connection between the client and server, meaning they can both send and receive data from each other simultaneously. After the 3-way handshake in the screenshot, an HTTP get request is made by the web browser for the website; the server ACKnowledges this and sends the website data to the web browser. For ending the connection, a 4-way handshake is used. In the screenshot, the client first ACKnowledges that it has successfully received the HTTP data, and then the sever sends out a FIN packet, which the client ACKnowledges, and then the client sends out a FIN packet, which the sever then ACKnowleges, and then the connection times out, thus ending the data exchange
