| Abstract | In testing our multi-agent cyber security system, Ant-Based Cyber Defense (ABCD) we have found that pheromone efficacy, swarm formation, and cyber-security properties of a multi-agent system can be affected by non-uniform delay times experienced by the ant agents as they traverse on large-scale, real-world networks. This led to tests where we artificially induced delay on large sections of a network to experiment with swarms under different delay conditions. As predicted by queuing theory, we found that more agents gathered in grid sections with longer inter-node propagation/transmission delays and that the population of agents in the sections with longer delays was proportional to the delay times in that network section relative to the rest of the network. We verified the observed operational behavior via both simulation and queuing theoretic analysis and found that there may be no closed-form solution to the steady state of a system without static transition probabilities. In ABCD, transition probabilities are dynamic, arising from non-deterministic pheromone deposition rates. Without careful tuning of multi-agent security systems to a given network's delay characteristics the security provided may be significantly less than desired because agents may not be distributed as needed or required by the designers. We have used the findings in this study to discover parameters to help make this tuning possible. |

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.
