Routing Systems : Routing Protocols

Transmission Control Protocol/Internet Protocol (TCP/IP) are the basic communication protocols, which were designed to provide low level support for internetworking. This term is generally also used to refer to a more generalised collection of protocols developed by the internet community and U.S. Department of Defence.

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;

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

routing. In this chapter, we introduce some popular routing protocols in each of the three

A WSN is a type of wireless networks that consists of collection sensor nodes which are tiny devices. Each sensor node of the network has different processing capability. It may contain multiple types of memory (program, data and flash memories), have a RF transceiver, have a power source (e.g., batteries and solar cells), and accommodate various sensors and actuators. The nodes communicate wirelessly and often self-organize after being deployed in an ad hoc fashion [13, 14]. Optimum need of each sensor node is to maximize its own utility function. Also the whole network requires resource assignments balance to perform in a useful and efficient way. This chapter presents a brief survey on WSNs showing its types, characterizing features, protocols and applications.

It just doesn't get much simpler than the physical bus topology when it comes to connecting nodes on a Local Area Network (LAN). The most common implementation of a linear bus topology is IEEE 802.3 Ethernet. All devices in a bus topology are connected to a single cable called the bus, backbone, or ether. The transmission medium has a physical beginning and an end. All connections must be terminated with a resistor to keep data transmissions from being mistaken as network traffic. The terminating resistor must match the impedance of the cable.

The Wireless Routing Protocol (WRP) is a table-based distance-vector routing protocol. Each node in the network maintains a Distance table (DT), a Link-Cost table, a Routing table and a Message Retransmission list. The DT contains the network observation of the neighbours of a node. It contains a matrix where each element contains the distance and the one

The increasing usage of networks especially wireless networks for different applications, has moved to focus towards the design and optimal routing of the networks in the modern life. The use of wireless networks instead of wired networks solves many issues in real life. These challenges includes the Mobility, signal fading, power and energy, data rate, security etc.

Routing lies at the core of any NDN architecture. NDN projects have proposed diverse solutions for routing. In this survey, I present a list of major NDN routing projects and the comparative analysis of four proposed routing models based on performance evaluation factors. My perspective on the requirements of ideal content routing model is introduced based on results of the survey.

There are number of metrics which are helpful for deciding the efficiency of a protocol. In this work the parameters used to evaluate the efficiency of a protocol are the packet delivery ratio, packet statistics in the network and the throughput of the network. The protocols AODV and AODVBC are checked against these parameters for their performance. Packet delivery ratio of the network is improved as the mobility with respect to the number of nodes changes. Increase in the PDR (Packet delivery ratio is because of the less number of packet drops when AODVBC is used. Fig. 4 justifies the better performance of AODVBC routing protocol over AODV protocol in terms of less number of packets drop.

The further sections of survey paper are organized as follows: Section 2 provides the introduction about the different routing algorithms that we are comparing. Simulation setup and data traces used are under Section 3. Metrics to calculate algorithm performance are under section 4. Section 5 shows the performance comparisons for all the routing algorithms. Default parameter settings are used for this purpose. The performance comparison includes the average message replication statistics of each protocol, packet drop ratio, the message delivery cost, message overhead ratio for a protocol, Number of redundant packets in the network, total message forwards required in each network and lastly the packet wastage index. Section 6 comprises of

Abstract— Mobile Ad hoc Network (MANET) is a special self-describing wireless ad hoc network which consists of more number of nodes that can move randomly and erratically. Because of this infrastructure it enables many kinds of attacks and establish topology-exposure problem. Many of the existing multipath protocols may ignore the topology-exposure problem. In this, we proposed a TOpology-HIding multipath routing Protocol (TOHIP) for preventing attacks in topology-exposure. In TOHIP, the link connection information is hidden in route messages, so that the malicious nodes cannot conclude the network topology. In Route Reply phase, the protocol TOHIP can also be used to establish multiple node-disjoint routes and eliminate the unreliable route before transmitting packets in Route Probe phase. With the help of a newly designed protocol, security was assured and earned better capability of finding routes in MANET. The simulation result shows that TOHIP has given better performance when compared with Ad hoc On-demand Multipath Distance Vector (AOMDV) routing protocol.

This section has represents the over read of connected paper support the present analysis. These papers do not seem to be utterly associated with project approach however positively enhance the performance of network routing protocol.

Routing as we can say is selecting the best path in the network to transfer data from one point to another. And Routing algorithm on a router in computer networks decides on which incoming line a packet should travel and thus creating the routing decision. It depends on various factors like stability, robustness, simplicity, correctness, fairness and optimality.

Internet usage has skyrocketed in the last decade, propelled by web and multimedia applications. While the predominant way to access the Internet is still cable or fiber, an increasing number of users now demand mobile, ubiquitous access whether they are at home at work or on the move. For instance, they want to compare prices on the web while shopping at the local department store, access Internet “navigation” aids from their car, read e-mail while riding a bus or hold a project review while at the local coffee shop or in the airport lounge. The concept of wireless, mobile Internet is not new. When the packet switching technology, the fabric of the Internet, was introduced with the ARPANET in 1969, the Department of Defense immediately understood the potential of a packet switched radio technology to interconnect mobile nodes in the battlefield. Consequently, the ad hoc protocols must self-configure to adjust to environment, traffic and mission changes. What emerges from these characteristics if the vision of an extremely flexible, malleable and yet robust and formidable network architecture. Because of its mobile, non-infrastructure nature, the ad hoc network poses new design requirements. The first is self-configuration (of addresses and routing) in the expression of mobility. At the function level, ad hoc network users typically communicate and collaborate as teams. These applications thus require efficient group
