    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.

    The new great game in central asia : India's interests and challenges
    (Central University of Punjab, 2014) Thokar, Parvaiz Ahmad; Singh, Bawa
    The Great Game which divided Persia into a Russian-controlled northern zone, a nominally independent central zone, and a British-controlled southern zone, officially ended with the Anglo-Russian Convention of 1907. After the end of Cold War, Central Asia became the central point of attention by the world powers, US, Russia and China, EU etc and many other regional players. Possessing divergent interests, the competition among external powers in the region is popularly termed as the New Great Game. Central Asian governments are working to use renewed external involvement to their sovereign advantage, extract economic benefits and political support where possible. India considers the region as geo-strategically and economically vital to fulfill its various interests like energy, trade and investment, security etc and both the regions own multifaceted historical ties. Apart from economic and other commercial interests, India also considers the region vital for the security and stability of Afghanistan. At present Middle East region accomplishes the required energy imports of India but in recent times, the region turned more unstable. Hence Indian policymakers started thinking about an alternative source and identified Central Asia as the best option. Therefore, economic diplomacy remains India's basic policy thrust towards the region and needs no clash but a compatibility of interests with the new states. v India has to face many challenges to get connected with Central Asia like the New Great Game, lack of proper road link, religious extremism and terrorism, drug trafficking, small arms proliferation and the most challenging one that is NATO withdrawal from Afghanistan in 2014. India has to take lead to overcome the significant influence made by several regional powers and to make its own position extremely strong in the region. Hence this study will make an assessment about diverse interests that India possesses and various challenges due to role of external major powers in the region and also India's strategy to protect its interests in energy rich Central Asia.
