LIGHTWEIGHT SYBIL ATTACK DETECTION IN MANETS PDF

Due to the complex nature of MANETs and its resource constraint nodes, there has always been a need to develop lightweight security solutions. Since MANETs require a unique, distinct, and persistent identity per node in order for their security protocols to be viable, Sybil attacks pose a serious threat to such networks. A Sybil attacker can either create more than one identity on a single physical device in order to launch a coordinated attack on the network or can switch identities in order to weaken the detection process, thereby promoting lack of accountability in the network. In this research, we propose a lightweight scheme to detect the new identities of Sybil attackers without using centralized trusted third party or any extra hardware, such as directional antennae or a geographical positioning system. Through the help of extensive simulations and real-world testbed experiments, we are able to demonstrate that our proposed scheme detects Sybil identities with good accuracy even in the presence of mobility.

Due to the complex nature of MANETs and its resource constraint nodes, there has always been a need to develop lightweight security solutions. The vehicles may not have a direct internet connection.

The wireless roadside instruments may be connected to the internet, and then these allow the information from the vehicles to be sent over the internet. Personal Area Network is a network of various devices like laptop, mobile, PDAs within a range of an individual i. A measure of number of information units processed by a system in a given amount of time.

The aim was to have small, low power, low cost devices having efficient protocols for enhances scalability and survivability Jublin, Another way of defining throughput is the rate of successful message delivery over a communication channel.

Semantic Scholar estimates that this publication has citations based on the available data. KumarSwarnakaran Hemalatha Thus individuals and vehicles can be interconnected without a pre-existing communication infrastructure or when the employment of such infrastructure needs wireless extension. Complete Chapter List Search this Book: This has led to the idea of computing to emerge as one of the research hotspots within the computer science world.

Some MANETs are restricted to a neighborhood area of wireless devices, whereas others could also be connected to the internet.

The exponential growth in the use of mobile devices like laptops, smartphones, tabs, Ipads, PDAs has bought a detectioj within the computing world. Thus, this type of wireless network is considered as Mobile Ad hoc network. Whereas the nodes that are not within the direct communication range use intermediate nodes to communicate with one another. These days at one particular instance, a user can utilize series of electronic platforms to access information at any place and at any time.

Manets are usually not secure as they are dynamic in nature. A Denial of Service DoS attack is an attempt to make the network resources unavailable to its intended user.

It has units of time. This attack can decrease the trust of any legitimate node by using identity of that node and accumulate the secret or important data. Since eavesdropping activities do not affect the normal operation of network transmission, both the sender and the recipient can hardly notice that the data has been stolen, intercepted or defaced. Signal to Noise Ratio is a measure to detect the amount of signal in the presence of background noise.

MANETs represent complex distributed systems that may This forms a one-to-one mapping between an identity and also be part of a huge complex system, such as a complex an entity and that is usually assumed either implicitly or system-of-systems used for crisis management operations. Due to the complex nature of MANETs and its resource constraint explicitly by many protocol mechanisms; hence two identities nodes, there has always been a need to develop lightweight implies two distinct nodes. Unfortunately malicious nodes can security solutions. Since MANETs require a unique, distinct, and illegitimately claim multiple identities and violate this one-to- persistent identity per node in order for their security protocols to one mapping of identity and entity philosophy. Douceur [2] be viable, Sybil attacks pose a serious threat to such networks.
