Item Performance evaluation of manet routing protocols dsdv, tora enhanced tora(Central University of Punjab, 2014) Kaur, Amandeep; MeenakshiWireless Networking has become the phrase du jour these days because of an attractive number of benefits it offers to the end users, by enabling them to access and share a wide pool of resources and information across the globe. Mobile ad hoc networks (MANETs) are a kind of infrastructure less wireless networks in which all the nodes act as peers and themselves configure the network. Mobile ad hoc networks are an open area of research because of its applicability in a number of areas like tactical networks, emergency services and education. One of the major challenges in networking is the efficient, accurate, reliable, secure and immediate delivery of data from source to destination. Therefore, the efficient routing of data across the mobile ad hoc network is a major concern of researchers all over the world. Several routing protocols have been developed to send data efficiently across mobile ad hoc networks. These protocols have been divided into three categories- Proactive, Reactive and Hybrid. The performance evaluation of these protocols has been going on since a long time. Most of the current research focuses on the pause times, simulation times and network size to measure the performance of various mobile ad hoc network routing protocols. A very few work has been done on the performance analysis of protocols by varying the underlying mobility models and traffic patterns. This dissertation work is focused on the improvement of the poor performance of TORA with the rise in number of traffic connections. This behavior has been credited to the link sensing mechanism of Internet MANET Encapsulation protocol (IMEP). IMEP is a multi-purpose network-layer protocol that supports the operation of many routing protocols including TORA. It provides mechanism for sensing the status of links in TORA. This link sensing mechanism has been investigated and proposed modification by K. H. Lim and A. Datta has been implemented to observe improvement in the overall performance of Enhanced-TORA protocol in comparison with original TORA. iv Through this research, investigations have been made into the behavior of DSDV, and TORA mobile ad hoc routing protocols by varying the underlying mobility models (Random Waypoint, Random Direction and Manhattan Grid model) and Traffic patterns (FTP, TELNET, HTTP). The metrics used to analyze the performance are Throughput, Average End to End delay, Routing overhead, Packet Delivery Ratio and Packet Loss. This research draws an analysis whether under which mobility model and traffic pattern combination these protocols give the best performance. Results show that DSDV gives best performance under Manhattan Grid Mobility model and FTP traffic pattern. Whereas, TORA and Enhanced-TORA give best performance under Random Direction Mobility model and FTP traffic. The performance of Enhanced-TORA is then compared with original TORA using 10 traffic connections under Random Direction mobility model and FTP Traffic and it was observed that Enhanced-TORA outperformed original TORA thereby eliminating the problem of performance degradation with rise in number of connectionsItem Water consumption pattern in hpuseholds of urban south asia : A study of bathinda city(Central University of Punjab, 2014) Kaur, Amandeep; Singh, Kiran KWater is used by human being by different ways; mainly it is divided into three different sectors: Agriculture sector, Industrial Sector and Domestic sector. Three of them have different factors that affect the consumption level of water. Many factors like culture, food habits, working conditions, income, and technological advancement determine the requirement of water in any area. South Asia has been fortunate in having abundant fresh water reserve but the increasing population and overexploitation of surface and ground water over the past few decades has resulted in water scarcity in this region. Water availability in South Asian countries and their cities varies with area and socio-economic groups. That availability leads to varied water consumption patterns at domestic household. People in cities have access to water at all times and places which sent a wrong signal that the water is available in plenty. These type of wrong information leads to wastage of water at domestic household. While many people are known to the fact that water resources are declining day by day but their water consumption patterns at their household are not in favour of water resources conservation. More number of water appliances, bathing and washing habits, method of watering plants at home leads to wastage of water at home. On the other hand, accessibility to fresh and clean water is also a big question. This study is an effort to analyse people behaviour and perception to know the water consumption pattern at domestic household in Bathinda city, fifth largest state of Punjab. Many socio-economic factors affect the consumption pattern, perception and awareness in domestic households. The study is based on primary and secondary data. The household survey was conducted to know the v consumption, availability, access and people awareness for conservation of water in domestic households. Water consumption will be correlated to socio economic factors such as income, household size, education level etc.Item India's trade with six EU countries: Trends and patterns(Central University of Punjab, 2013) Kaur, Amandeep; Kaur, SandeepIndia and European Union trade relations go back to 1960s. Both sides started their bilateral trade relations after their first summit which, was held in 2000 and after that India-EU has gone through various rounds of summits and negotiations for improving the bilateral trade ties. As a result, Free Trade Agreement was agreed upon between them in 2007 but it is still not fully implemented. EU is India's largest trading partner which has accounted 14.8 percent in its total trade in 2011. The study has taken up six nations of EU namely Belgium, France, Germany, Italy, Netherlands and UK as these countries have a large average share of trade with India during 1996-2011. The study strives to find out the trade competitiveness and patterns of India with these six EU countries by using various indices like Trade Intensity Index (TII), Revealed Comparative Advantage Index (RCA), Revealed Symmetric Comparative Advantage Index (RSCA) and Intra Industry Trade Index (IIT). The study finds out that India's growth of exports are more as compared to imports towards these countries. Among EU's six countries, UK, Germany, Netherlands and France are the main trade partners of India. Regarding commodity composition, India's 'iron and steel', 'organic chemicals' and 'electrical equipments' are the main top ten export commodities and 'pearls and precious stones metals & coins etc', 'organic chemicals', 'electrical equipment', 'iron and steel', 'nuclear reactors', 'optical photos' and 'commodities elsewhere classified' are in the top ten import commodities of India from these six countries. Regarding RCA index of India with these countries commodities namely 'silk', 'cotton', 'articles of accessories' and 'articles of leather' and 'animals guts' have still remained in top position during the whole study period and with the severe effect of Euro crisis, some of the commodities lost their earlier place in 2011 like Indian 'cotton', 'tea coffee' and 'carpets'. RSCA index shows almost same results for these commodities. Then in the IIT index for 'chemicals and allied industries', 'wood and wood products', 'metals' and 'machinery electrical' accounted higher value of IIT index in 2000 but it has been decreasing in 2011. The study suggested that, there is diversification in goods and latest technology should be used to benefit from bilateral trade. There is still further scope to improve the FDI flows between India-EU. India should adopt policies which are open, attractive and investor friendly to enhance the FDI flows. There is a need to implement the FTA agreement at fast pace, for this there is great requirement of political will.Item Socio-economic impact of Bt cotton in Bathinda district of Punjab(Central University of Punjab, 2011) Kaur, Amandeep; Kahlon, A. S.An attempt has been made in this study to assess the socio-economic impact of Bt cotton in Bathinda district of Punjab. The assessment is based mainly on primary data which is processed by applying regression analysis, Probit model and simple averages. On an average, 77.67 percent of total cropped area of the district is under Bt cotton cultivation as compared to 0.39 percent of Desi cotton cultivation. The decision of a farmer to adopt Bt cotton is significantly influenced by age and education of the farmer i.e. younger and better educated farmers prefer Bt cotton to Desi cotton. The study reveals that Bt cotton farmers are earning relatively higher net returns than that of Desi cotton farmers by Rs 19336 per acre due to relatively higher yield of 809 kg per acre as compared to Desi cotton yield of 420 kg per acre. The category wise analysis of Bt cotton farmers and Desi cotton farmers shows that farmers belonging to Others? category are earning more net returns than the Marginal and Small farmers. It was largely due to increased area under irrigation by Others? category of farmers. The social impact on the basis of perceptions of the sample farmers also revealed that Bt cotton is not adversely impacting health and reduced number of sprays has improved the quality of environment. Not a single farmer attributed the suicide cases to Bt cotton. Although Bt cotton cultivation is economically viable, yet higher seed cost hinders the pace of adoption by the Marginal and Small farmers. It is suggested that there is an urgent need for government to regulate the price of seeds of Bt cotton
