    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.

    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.
