For each Express train there is a "TATKAL" scheme that reserves few seats on emergency basis. In the existing scheme for each seat a ticket is issued after charging a fixed price. However,(More)
Participatory Sensing system (PSS) is being thought of as an alternative model in the pervasive computing environment, to collect effective data from mobile human agents, where deployment of sensor agents to collect data will be costly. One of the main difficulties in collecting data from the human agents is that, they are not willing to participate in this(More)
—The doctors (or expert consultants) are the critical resources on which the success of critical medical cases are heavily dependent. With the emerging technologies (such as video conferencing, smartphone, etc.) this is no longer a dream but a true fact, that for critical medical cases in a hospital, expert consultants from around the world could be hired,(More)

As the success of any critical operation (or surgery) is heavily dependent on ECs, so they can be thought of as one of the crucial elements of the healthcare domain. In many(More)
The economic settings of allocating resources in cloud computing have been studied, so far, by the concept of mechanism design with money. However in some applications resources can be disseminated by the service providers to some users free of cost. The problem of allocating resources in this charitable environment predominantly becomes challenging if the(More)
Agents (specially humans) with smart devices are stemming with astounding rapidity and that may play a big role in information and communication technology apart from being used only as a mere calling devices. Inculcating the power of smart devices carried by the agents in several different applications is commonly termed as participatory sensing (PS). In(More)
—First-come-first-serve (FCFS) scheme is used for selling the goods in market that is a multi-million dollar industry for any popular event. But in a competitive environment is this FCFS efficient? In earlier literature it has been shown that the auction based alternative solutions using the framework of mechanism design, a sub field of game theory [18] can(More)
