Introduction

1.1 Introduction:

A Mobile Ad hoc Networks (MANETs) stand for a structure of wireless mobile hosts that can dynamically and liberally self organize in to temporary and uninformed network topologies, allocating devices and people to faultlessly communicate without any kinds of pre-existing design of communication structure. The appliances of these networks are extremely necessary in areas like lecture theatres, conference halls, battlefields emergency rescue services, battlefields and other places whenever it’s become very difficult to employment the network infrastructures. In a Mobile Ad Hoc Network the network may experience unpredictable and rapid topology changes because of arbitrarily node movement. Routing paths in Mobile Ad hoc Network possibly have multiple hops, and each node in Mobile Ad hoc Network has the responsibility to perform like a router [1]. So each node in the Ad hoc networking is responsible for forwarding data packets to other nodes [2]. Routing in Mobile Ad hoc Network has been a tough job ever while the wireless mobile networks came into reality because of frequently change in network. Development of dynamic routing protocols is a huge challenge in the design of Ad hoc networks which can proficiently find routes among. These protocols are classified into hybrid, pro-active and reactive routing protocols [3] and the identification of the most appropriate routing protocol to be used depends on various facts which are scalability, traffic and mobility models and quality of service.

The CBR (Constant Bit Rate) and TCP (Transmission Control Protocol) are mobility and traffic models. These models perform a significant role in calculating the performance of routing protocols. The scope of this paper is to compare and evaluate the performance of TCP against CBR traffic models using AODV routing protocol.

    The simulation results of this thesis can allow to conclude that using the multipath with quality of service is the best method to get less jitter and more throughput as compare with another published paper and this algorithm gets less jitter without using multipath as in the first experiment, but the throughput is reduced in big network as in the sixth experiment because the transfer packet from client to server not fixed ,the packet take one path in first transfer but in second transfer may take another path to send to server and this can reduce the network throughput in random network .…

    AODV has pooled properties of both DSR and DSDV. It uses route discovery process for sustaining route information through the basis of routing table. It is a reactive protocol as it doesn’t need to establish or maintain routes to nodes that are not involved in the communication. AODV handles route discovery process with Route Request (RREQ) messages to broadcast to neighbour nodes. The message floods through the network till the desired destination is reached. Sequence number guarantees the loop freedom. The destination node at once receiving a RREQ unicasts a Route Reply (RREP) back to the source node. Node transmitting a RREP message creates routing table entries for forward route. For route maintenance, nodes send HELLO messages intermittently to neighbour nodes. If any node in the network miss the mark to receive three consecutive HELLO messages from its neighbour, it presumes that link to that particular node is down. A node that perceive a broken link directs a Route Error (RERR) message to any upstream node. At once a node receives a RERR message it will signpost a new source discovery process. The AODV protocol uses sequence numbers to determine the timeliness of each packet and to…

    TCP / IP Model - provides end-to-end connectivity specifying how data should be formatted, addressed, transmitted, routed and received at the destination. This functionality has been organized into four abstraction layers which are used to sort all related protocols according to the scope of networking involved.[1][2] From lowest to highest, the layers are the link layer, containing communication technologies for a single network segment (link), the internet layer, connecting hosts across independent networks, thus establishing internetworking.…

    This book provides generic approach architecture for the implementation of the wireless sensor networks. It proposes for a move into the routing protocols and improvement of networks through routing optimization, medium access and control of power while at the same time fulfilling the daily goals. It emphasizes on the importance to node information in the many wireless sensor network applications as well as the communication protocol. This solution can be applicable in the case of NHS since the use of wireless sensor networks can greatly help in transferring large data files, including the imaging files to…

    Designing secure key distribution in an ad-hoc network might be an extremely hard task. Any reliance on a certificate of authority is not trivial at all, for the same reasons that reliance in any centralized authority is problematic. Additional problems include the increased packet sizes required by authentication extensions, unicast/multicast routing, Quality of Service support and power aware routing. Furthermore, due to the limited transmission range of wireless network interfaces, multiple hops may be needed to exchange data between nodes in the network (c.f.…

    The factors that account for the success and popularity of TCP/IP are integrated addressing system, design for routing, underlying network independence, scalability, open standards and development process, and university. TCP/IP includes within it a system for identifying and addressing devices on both small and large networks. Unlike some network layer protocols, TCP/IP is specifically designed to facilitate the routing of info over a network of arbitrary complexity. TCP/IP operates primarily at layers three and above, and includes provisions to allow it to function on almost any lower layer technology, including LANs, wireless LANs, and WANs of various sorts. One of the most amazing characteristics of TCP/IP is how scalable its protocols have proven to be. The TCP/IP standards are not proprietary, but open standards freely available to the public. Everyone uses TCP/IP because everyone uses it.…

    In this lab, we’ll investigate the behavior of TCP in detail. We’ll do so by analyzing a trace of the TCP segments sent and received in transferring a 150KB file (containing the text of Lewis Carrol’ s Alice’s Adventures in Wonderland) from your computer to a remote server. We’ll study TCP’s use of sequence and acknowledgement numbers for providing reliable data transfer; we’ll see TCP’s congestion control algorithm – slow start and congestion avoidance – in action; and we’ll look at TCP’s receiver-advertised flow control mechanism. We’ll also briefly consider TCP connection setup and we’ll investigate the performance (throughput and round-trip time) of the TCP connection between your computer and the server.…

    IEEE 802.11 is the de facto standard for WLANs. It specifies both the medium access control (MAC) and the physical (PHY) layers for WLANs. The MAC layer operates on top of one of several physical layers. Medium access is performed using Carrier Sense Multiple Access with Collision Avoidance. However, simple CSMA is susceptible to the hidden node problem, especially in so called ad hoc networks where a node may communicate directly with every other node in range or using intermediate nodes as relays otherwise. Hidden nodes cause costly packet collisions and thus significantly affect network performance. In order to combat the hidden node problem, a mechanism known as Request to Send/Clear to Send (RTS/CTS) handshake is often used. RTS/CTS mechanism is supported in the IEEE 802.11 family of standards. The RTS/CTS mechanism was initially proposed in a protocol called Multiple- Access with Collision Avoidance (MACA). From a network point of view, one of the primary reasons for using the RTS/CTS mechanism is to avoid network congestion resulting from frequent packet collisions. Figure 1 depicts a conceptual “throughput versus Packet Size” curve for a network. In the presence of congestion, the throughput goes to zero as the Packet Size is increased beyond a certain value. A properly designed network, on the other hand, maintains the maximum throughput as the Packet Size goes to infinity.…
