A PTP method in network security for misbehavior detection system is a method of detecting malicious misbehavior activity within networks. The System detects the malicious node and blocks them by adding into Blacklist. Malicious nodes are the compromised machine present in the network, which performs the task given by bot server i.e. it does not forward the legitimate message to another node in...

Wireless sensor networks (WSNs) consists of small nodes with constrain capabilities. It enables numerous applications with distributed network infrastructure. With its nature and application scenario, security of WSN had drawn a great attention. In malicious environments for a functional WSN, security mechanisms are essential. Malicious or internal attacker has gained attention as the most chal...

Sensor network applications may involve dealing with the remote, distributed monitoring of inaccessible and hostile locations. These networks are vulnerable to security breaches both physically and electronically. The sensor nodes, once compromised, can send erroneous data to the base station ,thereby possibly compromising network effectiveness. The sensor nodes are organized in a hierarchy whe...

In Mobile Adhoc Networks (MANETs), routing attacks are considered as a serious issue. However, in the presence of malicious nodes, the networks are affected by various kinds of attacks. The malicious node(s) can attack a MANET in different ways, such as sending fake messages several times; fake routing information and advertising fake links to disrupt routing operations. Black hole attacks are ...

Due to the disconnected and store-and-forward architecture in multimedia social networks (MSNs), routing becomes a great challenge with the frequent path disruptions. Moreover, some nodes in MSNs tend to be selfish or malicious, e.g. they sometimes will not forward packets for other nodes or will launch passive and active attacks in order to save their limited resources such as bandwidth, batte...

In this paper, we are concerned of a particularly severe security attack that affects the ad hoc networks routing protocols, it is called the wormhole attack. We can think of wormhole attack as a two phase process launched by one or several malicious nodes. In the first phase, these malicious nodes, called wormhole nodes, try to lure legitimate nodes to send data to other nodes via them. In the...

This paper addresses the issue of the security of Internet Coordinate Systems, by proposing a general method for malicious behavior detection during coordinate computations. We first show that the dynamics of a node, in a coordinate system without abnormal or malicious behavior, can be modeled by a Linear State Space model and tracked by a Kalman filter. Then we show, that the obtained model ca...

In distributed systems, it is difficult to predict whether the node is genuine or not and this may lead to the addition of selfish/ malicious nodes. The selfish/malicious nodes are the nodes that continue the execution of their codes for unknown/prolonged duration. For allotting the nodes with resources, the mutual exclusion algorithms, either token based, non-token based quorum-based or agreem...
