    Performance analysis of aodv for wormhole attack using different mobility models
    (Central University of Punjab, 2014) Kaur, Gurmeet; Kaur, Amanpreet
    Mobile Ad-Hoc Network (MANET) is a type of temporary wireless network, in which the nodes are mobile and have dynamic network topology. According to structural arrangement, wireless networks are classified into two main types: fixed infrastructure wireless networks and non-infrastructure wireless networks. Mobile Ad-Hoc Networks (MANETs) fall under the type of infrastructure less wireless networks. Mobile nodes can communicate to each other through wireless links in this type of an autonomous system. At any time, whenever required nodes can join or leave the network as nodes are free to move. Although various routing protocols are used in the communication process but those protocols have numerous security complexities. An intruder can perform many attacks (both active and passive attacks) through different security flaws. Wormhole attack is an active attack in the context of mobile ad-hoc networks that disrupts the normal routing functioning of any routing protocol. In this work, an attempt has been made to analyze and compare the performance of demand oriented or reactive routing protocol: Ad-hoc On Demand Distance Vector (AODV) with two approaches: AODV without wormhole attack and AODV under attack using two mobility models viz. Random Way Point Model and Reference Point Group Mobility Model. Evaluation of two examined approaches has been done in terms of performance metrics such as Average Throughput, PDR (Packet Delivery Ratio), Jitter, Average End to End Delay and Packet Drop Rate. An approach has also been used to analyze participated malicious nodes in the wormhole peer list. Along with this, the attack has been detected with the help of metrics such as Average Throughput, Average End to End Delay, Jitter and Packet Delivery Ratio.

    Public transport and mobility in urban south asia (A study of bathinda city)
    (Central University of Punjab, 2014) Kumar, Gaurav; Singh, Kiran. K
    Public transport plays a vital role in the development of the modern era as an integral part of the socio-economic and political structure of the country. Thus urban transport, its infrastructure and traffic management should involve optimal integration of the means and ways of mobility to create maximum ease and comfort maintaining the socioeconomic and physical integration of the city. It has a great influence and impact on regional patterns of development, economic viability, and environment and on maintaining socially acceptable levels of quality of life. As the cities expand, there is a consequential expansion of transportation needs. Urbanization brings with it increased affluence which results in increased mobility. There is daily mobility of people on account of social, religious, economic, political, entertainment needs. In developing countries where urbanization rates are increasing, the combined effect of high rapid growth coupled with increased mobility and large increases in population is a cause for concern. The rapid growth and utilization of private transport is becoming a source of congestion as well as pollution in the cities. There is no doubt that private transport has become advantageous over public transport but their unprecedented growth will have unimaginable consequences. This study is an attempt to evaluate public transport and urban mobility in Bathinda, what is the quality and quality related perception about public transport and what is the nature of mobility? In the situation of rapid growth in the private vehicle in the city the role of public transport in the mobility of v people has become crucial to understand. The data required for the present study has been collected from both primary and secondary sources. The secondary data for the study has been collected from government, semi-government and private sources such as from the City Bus Enterprise, Punjab Roads Authority, District Transport office, books, articles, research papers, journals, magazines & other internet resources. The primary data has been collected through field survey taking personal interviews which was done under varying circumstances such as taking bus rides, riding in autos, waiting in line for a bus to come and also visiting different wards of the city. Collected data were analysed and presented using descriptive statistical methods.
