The document presents a technique to detect nodes that selectively drop or modify packets in wireless sensor networks. It proposes using a triple key distribution method where any three consecutive nodes on a routing path secure communications with each other. Simulation results showed that the proposed triple key method efficiently detects malicious nodes and identifies attacks earlier than some recently proposed approaches.
Secure and Reliable Data Routing in Wireless Sensor Networkdbpublications
Wireless Sensor Networks (WSNs) are materializing as one of the dominant technologies of the future because of their large range of applications in military and civilian fields. Because of their operating behavior, they are often neglected and thus vulnerable to various types of attacks. For instance, an attacker could catch sensor nodes, getting all the information saved therein-sensor nodes are generally considered to not be temper-proof. Hence, an attacker may clone cached sensor nodes and use them in the network to conduct a variety of mischievous activities. As the decisions taken by a sensor network rely on the information gathered by the sensor nodes, if an adversary inhibits the necessary or confidential data from being forwarded to the BS/ target, this will cause the whole breakdown of the network or outcomes in the wrong judgment being made, possibly causing deliberate loss. There are many types of attacks such as compromised node, denial of service attack, black hole attack, etc. Hence there is a necessity to find all such attacks in WSN, and to safely route our sensitive information to the target. This paper represents the survey of some types of attacks and there detection techniques. Also the survey includes different techniques for secure and reliable data collection in Wireless Sensor Networks.
A black-hole attack in the Mobile Ad-hoc NETwork (MANET) is an attack occurs due to malicious nodes,
which attracts the data packets by falsely advertising a fresh route to the destination. In this paper, we
present a clustering approach in Ad-hoc On-demand Distance Vector (AODV) routing protocol for the
detection and prevention of black-hole attack in MANETs. In this approach every member of the cluster will
ping once to the cluster head, to detect the peculiar difference between the number of data packets received
and forwarded by the node. If anomalousness is perceived, all the nodes will obscure the malicious nodes
from the network.

Secure dynamic source routing protocol for defending black hole attacks in mo...nooriasukmaningtyas
Wireless Ad Hoc Network is a dynamically organized network on emergency
situations, in which a group of wireless devices send data among themselves
without requiring any base stations for forwarding data. Here the nodes itself
perform the functions of routing. This important characteristic of mobile ad
hoc networks allows the hassle free set up of the network for
communications in different crisis such as battlefield and natural disaster
zones. Multi hop communication in MANET is achieved by the cooperation
of nodes in forwarding data packets. This feature of MANET is largely
exploited to launch a security attack called black hole attack. A light weight
solution called SEC-DSR is proposed to defend the network from black hole
attack and enables communication among nodes even in the presence of
attackers. In this scheme, by analyzing only the control packets used for
routing in the network, the compromised nodes launching the attack are
identified. From the collective judgment by the participating nodes in the
routing path, a secure route free of black hole nodes is selected for
communication by the host. Simulation results validate and ensure the
effectiveness of the proposed solution tested on an ad hoc network with
compromised black hole nodes.

SECURED GREEDY PERIMETER STATELESS ROUTING FOR WIRELESS SENSOR NETWORKS ijasuc
Wireless sensor networks are collections of large number of sensor nodes. The sensor nodes are featured
with limited energy, computation and transmission power. Each node in the network coordinates with
every other node in forwarding their packets to reach the destination. Since these nodes operate in a
physically insecure environment; they are vulnerable to different types of attacks such as selective
forwarding and sinkhole. These attacks can inject malicious packets by compromising the node.
Geographical routing protocols of wireless sensor networks have been developed without considering the
security aspects against these attacks. In this paper, a secure routing protocol named secured greedy
perimeter stateless routing protocol (S-GPSR) is proposed for mobile sensor networks by incorporating
trust based mechanism in the existing greedy perimeter stateless routing protocol (GPSR). Simulation
results prove that S-GPSR outperforms the GPSR by reducing the overhead and improving the delivery

A Secure message exchange and anti-jamming mechanism in manetIJSRD
Secure neighbor discovery is the fundamental process in the MANET deployed in aggressive environment. It refers to the process that nodes exchange messages to discover and authenticate each other. It is defenseless to the jamming attack in which the adversary intentionally transmits signals to prevent neighboring nodes from exchanging messages. Existing anti-jamming communications depends on JR-SND. The JR-SND, a jamming-resilient secure neighbor discovery scheme for MANETs based on Random spread-code pre-distribution and Direct Sequence Spread Spectrum (DSSS). In Existing, they prevent the jamming and introduce the anti-jamming mechanism using DSSS introduce the secure message exchange mechanism and prevent the collisions during packet transmission. But in this we lack of introducing to detect the selfish and malicious nodes in the network. For this, in the Future Work we will enhance the work by detecting the selfish nodes using Watchdog and Neighbor Coverage-based Probabilistic Rebroadcast Protocol (NCPR).
TRIDNT: THE TRUST-BASED ROUTING PROTOCOL WITH CONTROLLED DEGREE OF NODE SELFI...IJNSA Journal
In Mobile ad-hoc network, nodes must cooperate to achieve the routing purposes. Node misbehaviour due to selfish or malicious intention could significantly degrade the performance of MANET because most existing routing protocols in MANET are aiming at finding most efficiency path. In this paper, we propose a Two node-disjoint Routes protocol for Isolating Dropper Node in MANET (TRIDNT) to deal with misbehaviour in MANET. TRIDNT allows some degree of selfishness to give an incentive to the selfish nodes to declare itself to its neighbours, which reduce the misbehaving nodes searching time. In TRIDNT two node-disjoint routes between the source and destination are selected based on their trust values. We use both DLL-ACK and end-to-end TCP-ACK to monitor the behaviour of routing path nodes: if a malicious behaviour is detected then the path searching tool starts to identify the malicious nodes and isolate them. Finally by using a mathematical analysis we find that our proposed protocol reduces the searching time of malicious nodes comparing to the route expected life time, and avoids the isolated misbehaving node from sharing in all future routes, which improve the overall network throughput.

A Novel Acknowledgement based Intrusion Detection System for MANETsIJMER
In Mobile Ad Hoc Networks(MANETs), a set of interacting nodes should cooperatively
implement the routing functions to enable end-to-end communication along dynamic paths composed by
multi-hop wireless links. Several multi-hop routing protocols have been proposed for ad hoc networks,
and most popular ones include: Dynamic Source Routing (DSR), Optimized Link-State Routing (OLSR),
Ad Hoc On-Demand Distance Vector (AODV) and Destination- Sequenced Distance-Vector (DSDV).
Most of these protocols rely on the assumption of a trustworthy cooperation among all participating
nodes; unfortunately, this may not be a realistic assumption in real hosts. Malicious hosts could exploit
the weakness of MANET to launch various kinds of attacks. Node mobility on ad hoc network cannot be
restricted. As results, many Intrusion Detection System(IDS) solutions have been proposed for the wired
network, which they are defined on strategic points such as switches, gateways, and routers, can not be
implemented on the MANET. Thus, the wired network IDS characteristics must be modified prior to be
implemented in the ad hoc network. Thus an IDS should be added to enhance the security level of
MANETs. If MANET can detect the attackers as soon as they enter the network, we will be able to
completely eliminate the potential vulnerabilities caused by compromised nodes at the first time. IDSs
usually act as the second layer in MANETs. This paper presents an novel IDS for MANETs which is
based on acknowledgements.
In this paper we propose a system that allows a safe and secure data transfer in MANETs between the source and the destination. As MANETs are unplanned networks and networks of instant communication, they are prone to attacks like disclosure, brute force attacks etc. In this paper we mainly concentrate on limiting the disclosure attacks in MANETs. Disclosure attack means that the network is monitored quietly without modifying it. The monitoring of network is possible only if the traffic is known. Hiding of traffic between the source and destination would prevent disclosure attacks in MANETs. To hide the traffic between the source and destination we must identify it. The traffic is identified using STARS(Statistical Traffic Pattern Discovery System for MANETs) technique. Using this technique, the traffic is made observable only for the intermediary nodes and the data is sent via intermediary nodes to the destination as single hop. The data which is sent as single hop by hop via intermediary nodes prevents the malicious node from knowing the original source and destination and thus preventing MANETs from disclosure attack.
Advisedly delayed packet attack on tcp based mobile ad-hoc networkseSAT Journals
Abstract Efficient routing in mobile ad-hoc networks (MANETs) is a challenging task due to its varying physical channel characteristics, dynamic topology and un-centralized communication. Furthermore, multihop routing is required when the source-destination pairs are not in each other’s communication range. Due to the above challenges these networks are vulnerable to various types of attacks on various layers of the TCP/IP protocol stack. In this thesis, we implement and analyze an attack called advisedly delay packet attack on ad-hoc on-demand distance vector (AODV) routing protocol. The advisedly delay packet attack is an attack that effects the TCP-based as well as UDP-based data transmissions but in this thesis we will also see how it exploits the TCP congestion control mechanism to decrease the throughput of the network. In this attack, the attacker exploit the period of retransmission time out (RTO) of the sender and attack in such a way so the sender is always transmitting in the slow start phase.

With its wireless and distributed nature it is exposed to several security threats. One of the threats in MANET is the wormhole attack.

Link Reliability based Detection and Predecessor base Route Establishment for...IJERA Editor
Mobile Ad hoc Network (MANET) is consists of mobile hosts or sensor nodes proficient of functioning in
absence of infrastructure. Such networks should be capable of self forming, self organizing, self managing, self
recovering, and able to operate under dynamic conditions. The multi-hop communication phenomenon is used
to sending information to receiver. To attain this, each mobile node depends on its neighbor or range node to
forward the data packet to the destination. In fact, most of previous studies on MANET have implicitly assumed
that nodes are cooperative such as node cooperation becomes a very important issue in MANET. The attacker in
dynamic network are easily affected the routing performance and data receiving ratio is affected as compared to
normal performance of network as well as dropping of data is enhanced. The packets percentage is degrades is
the confirmation of attacker misbehavior. The characteristics of wormhole attack is to making the tunnel and
reply the positive acknowledgement of destination at time of route request and drop all the data deliver through
tunnel. The attacker is identified by the past and current data receiving and forwarding in MANET. The
proposed IPS (Intrusion Detection and Prevention System) provides the security on the basis of link reliability.
In this work, we proposed new link reliability based security through Predecessor based Route Establishment of
detecting routing misbehavior of wormhole attack for prevention in MANET. The attacker is blocked through
the broadcasting scheme used by proposed prevention scheme from their actual identification to neighbors. The
security provider nodes are blocking the communication of attacker and provide the secure communication
among the mobile nodes. The performance of proposed scheme is evaluated through performance metrics like
PDR and throughput.
Discovering adaptive wireless sensor network using eSAT Journals
Abstract When we consider the standard Bellman-Ford algorithm, it uses static values of link cost function and distance function. These static values are stored in sink node so that the sink node requires memory to keep data safe. Therefore the space, message and time complexity of a network and node increases. To overcome this we discover Fast Time Dependent Shortest Path algorithm with message and used in network with β synchronizer. The FTSP algorithm uses dynamic values of link cost function and distance function and to store these values we are using vector compression method so that there is no need to store the data into the sink node. Because of this the message, time and space complexity of node will be decreases. Keywords- Duty cycle, Time dependent, β synchronizer

adds some checking responsibility to all its neighbours. SADEC proves more efficient than baseline local

In this work, we proposed new link reliability based security through Predecessor based Route Establishment of
detecting routing misbehavior of wormhole attack for prevention in MANET. The attacker is blocked through
the broadcasting scheme used by proposed prevention scheme from their actual identification to neighbors. The
security provider nodes are blocking the communication of attacker and provide the secure communication
among the mobile nodes. The performance of proposed scheme is evaluated through performance metrics like
PDR and throughput.
Discovering adaptive wireless sensor network using eSAT Journals
Abstract When we consider the standard Bellman-Ford algorithm, it uses static values of link cost function and distance function. These static values are stored in sink node so that the sink node requires memory to keep data safe. Therefore the space, message and time complexity of a network and node increases. To overcome this we discover Fast Time Dependent Shortest Path algorithm with message and used in network with β synchronizer. The FTSP algorithm uses dynamic values of link cost function and distance function and to store these values we are using vector compression method so that there is no need to store the data into the sink node. Because of this the message, time and space complexity of node will be decreases. Keywords- Duty cycle, Time dependent, β synchronizer

INFRINGEMENT PRECLUSION SYSTEM VIA SADEC: STEALTHY ATTACK DETECTION AND COUNT...ijp2p
In this paper we are providing a implementation details about simulated solution of stealthy packet drop
attack. Stealthy packet drop attack is a suite of four attack types, includes colluding collision, packet
misrouting, identity delegation and power control. Stealthy packet drop attacks disrupts the packet from
reaching to it’s destination through malicious behaviour. These attacks can be easily breakdown the
multi-hop wireless ad-hoc networks. Most widely preferred method for detecting attacks in wireless
network is behaviour based detection method. In this method a normal network overhears
communication from its neighbourhood. Here we are implementing a SADEC protocol which is
proposed solution of stealthy packet drop attacks. SADEC overlaid the base line local monitoring. In
base line local monitoring each neighbour maintains additional information about routing path also it
adds some checking responsibility to all its neighbours. SADEC proves more efficient than baseline local
monitoring to mitigate successfully all the stealthy attack types.

We all have good and bad thoughts from time to time and situation to situation. We are bombarded daily with spiraling thoughts(both negative and positive) creating all-consuming feel , making us difficult to manage with associated suffering. Good thoughts are like our Mob Signal (Positive thought) amidst noise(negative thought) in the atmosphere. Negative thoughts like noise outweigh positive thoughts. These thoughts often create unwanted confusion, trouble, stress and frustration in our mind as well as chaos in our physical world. Negative thoughts are also known as “distorted thinking”.
