| Abstract | We consider the problem of selfish misbehavior in scheduling algorithms of wireless networks. All wireless scheduling algorithms are designed under the assumption that network users will follow the algorithm specifications. In this paper, we study two scheduling algorithms in which a selfish user might misbehave in order to achieve better performance. In the first case, we consider a network that implements cross-layered rate control mechanism to determine arrival rate of users as well as link schedules. We explain a scenario in which a selfish user obtains extra throughput by misleading the scheduling component of the network. We find an equivalent optimization framework that captures misbehavior pattern of the selfish user. We present a solution to prevent such a greedy behavior by imposing a cost term on the utility function of the users. In the second part of the work, we consider the family of random access scheduling algorithms in which users of the wireless network wait for randomly chosen back-off intervals before accessing the medium. A selfish user might wait for smaller back-off in order to obtain an unfair advantage. We present a comparison method to detect such a greedy misbehavior. |

National Digital Library of India (NDLI) is a virtual repository of learning resources which is not just a repository with search/browse facilities but provides a host of services for the learner community. It is sponsored and mentored by Ministry of Education, Government of India, through its National Mission on Education through Information and Communication Technology (NMEICT). Filtered and federated searching is employed to facilitate focused searching so that learners can find the right resource with least effort and in minimum time. NDLI provides user group-specific services such as Examination Preparatory for School and College students and job aspirants. Services for Researchers and general learners are also provided. NDLI is designed to hold content of any language and provides interface support for 10 most widely used Indian languages. It is built to provide support for all academic levels including researchers and life-long learners, all disciplines, all popular forms of access devices and differently-abled learners. It is designed to enable people to learn and prepare from best practices from all over the world and to facilitate researchers to perform inter-linked exploration from multiple sources. It is developed, operated and maintained from Indian Institute of Technology Kharagpur.

NDLI is a conglomeration of freely available or institutionally contributed or donated or publisher managed contents. Almost all these contents are hosted and accessed from respective sources. The responsibility for authenticity, relevance, completeness, accuracy, reliability and suitability of these contents rests with the respective organization and NDLI has no responsibility or liability for these. Every effort is made to keep the NDLI portal up and running smoothly unless there are some unavoidable technical issues.
Ministry of Education, through its National Mission on Education through Information and Communication Technology (NMEICT), has sponsored and funded the National Digital Library of India (NDLI) project.
