An effective infrastructure for pocket switch network

This thesis report is submitted in partial fulfilment of the requirements for the degree of Bachelor of Science in Computer Science and Engineering, 2017.Cataloged from PDF version of thesis report.Includes bibliographical references (pages 61-64).In everyday life we are using Internet with fixed routing configurations such as Broadband, mobile data etc. Pocket Switch Networks (PSN) uses phones as the medium to connect with other people without a fixed cellular network or Internet. Since no fixed route to destination is available, problems arise when a node wants to send any message to a destination node. Packets are forwarded by flooding. Flooding causes increase in network congestion, resource consumption, delay and drop of packets. This approach can be applied to smaller networks but in large scale inefficient. To deliver messages in a larger network with high throughput and low latency we propose an infrastructure for PSN called ZoneCluster. First, we used probabilistic approach to eliminate flooding by forming clusters and having inter-cluster and intra-cluster routing. Secondly, we have saved the path of delivered messages from source to destination so that they can use the same path for faster communication. Lastly, we emphasize its application for larger networks such as an AD-Hoc WAN by comparing its performance with other protocols.Mohammad Kaif Ul MajedAnika MariamAfia NoshinMd. Jamiul Alam KhanB.
