Black-hole attack implemented in tcl


Hole Attack Implemented In TCL

In sample20.tcl, while simulating Blackhole attack in MANET, the blackhole attacker does not obey the communication model. Data Transmission is established between nodes using UDP agent and CBR traffic. Sender sends the data via attacker. Source node transfers data to attacker that does not have shortest route to Destination. Attacker does not forward data to its neighbors.

how to launch wormhole attack in ns2

A Mobile Ad hoc Network (MANET) comprises of mobile nodes that moves independently in an open environment. Communication between the nodes in a MANET is enabled with the aid of intermediate routers. The nature of MANET such as open medium, dynamic network topology, lack of centralized monitoring, and lack of clear defense mechanisms makes it vulnerable to several routing attacks. In MANET routing, there is a high probability for intermediate nodes to be malicious that might be a threat to the security. Worm ....etc

SEMINAR REPORT ON SLAMMER WORM: THE FASTEST SPREADING BOMBSHELL ON THE INTERNET

What is a computer virus?
Of primary concern is as to what a computer virus is. A virus is a
computer program that by your help or by attaching itself to some other
program is able to move from one computer to another. Typically these
programs are often malicious rather than beneficial even if they have
no payload associated with them as they snatch away the system
resources. There are several classes of code that fall under t ....etc

Selective Repeat is part of the automatic repeat-request (ARQ). With selective repeat, the sender sends a number of frames specified by a window size even without the need to wait for individual ACK from the receiver as in Go-Back-N ARQ. The receiver may selectively reject a single frame, which may be retransmitted alone; this contrasts with other forms of ARQ, which must send every frame from that point again. The receiver accepts out-of-order frames and buffers them. The sender individually retransmits frames that have timed out. ....etc

ABSTRACT
lwIP is an implementation of the TCP/IP protocol stack.. Interest for connecting small devices to existing network infrastructure such as global internet is steadily increasing. Such devices often has very limited CPU and memory resources and may not able to run an instance of TCP/IP protocol suite.
The focus of the lwIP stack is to reduce memory usage and code size, making lwIP suitable for use in small clients with very limited resources such as embedded systems. In order to reduce processing and memory demand ....etc

ABSTRACT
Bluetooth is one of the standards for wireless communication. Tt is excepted that the number of services provided over Bluetooth links will rapidly increase during the next few years. This puts hard demands on the Bluetooth specification, to preserve the interoperability between services offered from different manufactures. It's the Bluetooth profile specification that states the requirement on a Bluetooth applicat ....etc
