    Security Enhancement in AODV protocol against Network Layer Attacks
    (Excel India Publishers, 2014) Singh, Khushmeet; Kaur, Amanpreet
    A mobile Ad hoc network (MANET) is a wireless decentralized and self-configuring network in which nodes communicate with each other either directly or through intermediate nodes. Each node plays role of both transmitter and receiver. These unique features make MANET suitable for use in various emergency situations. Besides the various advantages, the open medium, rapidly changing topology and lack of centralized monitoring make MANET's vulnerable to different attacks. Hence it is vital to develop some security mechanism to protect MANET from attacks. In this paper performance of AODV Protocol is analyzed in presence of two network layer active attacks namely Blackhole and Malicious packet dropping. In active attack, an attacker disrupts the regular operation of the network, change the data or harm the system. Both these attacks are performed simultaneously on the network. Solution is proposed and simulated to prevent Blackhole attack. Malicious packet dropping attack is prevented by using watchdog intrusion detection system. Both solutions are combined and Performance of AODV and Modified AODV protocol is analysed under both attacks with respect to Packet Delivery Ratio, Average End-to-End Delay and Routing Overhead using NS2.

    A Comprehensive Review on Performance of AODV Protocol for Wormhole Attack
    (IJRET, 2014) Kaur, Gurmeet; Kaur, Amanpreet
    Wireless Networking is becoming very popular and interesting technology especially in these days as everyone wants wireless connectivity at anywhere anytime. It contains numerous wireless network technologies such as WiFi, WiMax, HSDPA and WiBro etc. Based on structural arrangement, wireless networks are categorized into two main categories: fixed infrastructure wireless networks and infrastructure less wireless networks. Mobile Ad-Hoc Networks (MANETs) come under the category of infrastructure less wireless networks, which is an autonomous system of mobile hosts connected by wireless links. Nodes are free to move and can join or leave the network at any time whenever required. Wireless ad hoc networks eradicate various problems which may come out while setting up the infrastructure. Communication among nodes in these networks is accomplished via different routing protocols. But these protocols have different security flaws and using these flaws, an attacker can launch many kinds of attacks. Wormhole attack is one of the serious attack in the context of mobile ad-hoc network, which can disrupt any routing channel completely. In this work, an attempt has been made to compare the performance of on-demand reactive routing protocol: Ad hoc On Demand Distance Vector (AODV) with two approaches: normal and attack. The performance metrics evaluated for the two examined approaches are Throughput, Packet Delivery Ratio, Delay and Jitter.

    Behavior analysis of LEACH protocol
    (Institute of Electrical and Electronics Engineers Inc., 2014) Maurya, Prashant; Kaur, Amanpreet; Choudhary, Rohit
    A wireless sensor network (WSN) is an emerging field comprising of sensor nodes with limited resources like power, memory etc. It is used to monitor the remote areas where recharging or replacing the battery power of sensor nodes is not possible. So, energy is a most challenging issue in case of WSN. Low-Energy Adaptive Clustering Hierarchy (LEACH) is the first significant protocol which consumes less amount of energy while routing the data to the base station. In this paper LEACH protocol has been analyzed with different percentage of cluster heads at different locations of base station in the network. ? 2014 IEEE.
