    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.

    Performance analysis of spin protocol under different security threats in wireless sensor networks
    (Central University of Punjab, 2014) Choudhary, Rohit; Kaur, Amanpreet
    The wireless sensor network consists of homogenous sensor nodes with limited energy and computational power which are self organisable. These nodes use radio frequency channels to communicate with each other wirelessly. Besides that wireless sensor networks are resource constrained with low energy and low bandwidth along with shorter communication range. The evolution of VLSI circuit technology has also enabled the development of wireless sensor networks. The ease of deployment and low cost availability of sensor devices has attracted much advancement in wireless sensor networks. The nodes with capabilities of sensing and computing help the administrator to observe particular environment like battle field, climatic conditions and weather forecasting in remote areas etc. This dissertation research is about the study of performance challenges in wireless sensor networks using Sensor Protocol for Information via Negotiation(SPIN) protocol under various security threats and to analyse their impact on SPIN. The empirical study has been carried to validate the issues studied in literature review by simulating the scenarios. On the basis of achieved observations the inference is drawn about the better protocol in sensor network and future recommendations are made for the analysis and enhancement.
