Choice of Routing Protocols TORA is a very good protocol but it is not preferred as it is quite complex and its was designed to scale to large networks while this thesis project is concentrating on small to medium sized networks.
These products are discussed below. This information is used to form the reply path for the route reply packet as AODV uses only symmetric links.
This feature allows TORA to scale up to larger networks but has higher overhead for smaller networks. There are many wireless products available but only few of them have ad hoc capabilities.
The qualities of AODV and DSR appear similar, but studies have shown that DSR has the edge over AODV in terms of number of packets successfully delivered under conditions of high node mobility and movement speed without significant expense in routing overhead bytes resulting from storing the entire route in the packet header [ 2 ].
There are two major phases for the protocol: Bluetooth Bluetooth is a technology that promises fast, secure, point-to-point wireless communications over short distances approximately 10 metres for devices as diverse as mobile phones, consumer electronics appliances and desktop computers [ 2 ].
An intermediate node may wish to record the routing information in its tables to improve performance but it is not mandatory. It uses spectrum in the unlicensed ISM 1 band of 2.
When ever a link failure occurs, the source is notified and a route discovery can be requested again if needed. Another feature of DSR is that it supports asymmetric links as a route reply can be piggybacked onto a new route request packet. The overhead will increase significantly for networks with larger hop diameters as more routing information will be contained in the packet headers.
The key difference between DSR and other protocols is the routing information is contained in the packet header. When intermediate nodes forwards the route request packet it records in its own tables which node the route request came from.
To find a route to the destination, the source broadcasts a route request packet.
The ad hoc mode allows for ad hoc network of nodes, but communication is point-to-point, with no multihop capabilities. TORA is a fairly complicated protocol but its main feature is that when a link fails the control messages are only propagates around the point of failure.
DSR is suited for small to medium sized networks as its overhead can scale all the way down to zero. Refer to Table for a table of features of these products. While other protocols need to re-initiate a route discovery when a link fails, TORA would be able to patch itself up around the point of failure.
Features of commercial ad hoc products. This broadcast message propagates through the network until it reaches an intermediate node that has recent route information about the destination or until it reaches the destination.
In an IEEE True ad hoc multihop Bluetooth devices are still yet to be commercialised. Although Bluetooth has been standardized for quite some time, Bluetooth devices are still not widely available.
It is a source-initiated on-demand protocol and it finds multiple routes between the source and the destination. Since the routing information is contained in the packet header then the intermediate nodes do not need to maintain routing information.
As the route reply packet traverses back to the source, the nodes along the reverse path enter the routing information into their tables.
The Bluetooth devices which are currently available are only point-to-point or point-to-multipoint devices. Since the IEEE MASTER THESIS REPORT MSc IN ELECTRICAL ENGINEERING WITH EMPHASIS ON TELECOMMUNICATION TRASMISSION CONTROL PROTOCOL (TCP) (AODV, DSR and TORA) are to be evaluated with three different TCP variants (Tahoe, Reno The thesis will address the scientific society about the TCP and MANET implementations in.
