ROBUST COMMUNICATION IN HETEROGENEOUS AND DISTRIBUTED SYSTEMS

Abstract: This thesis work has aimed to implement a robust communication system for military aircrafts produced by Saab. A big part of the thesis focuses on a comparison study of different possible designs and their impact on the system. From the comparison study a decentralized, Peer to Peer, Publish/Subscribe system was selected for implementation. All publications are sent directly from a publisher to the subscribers without any intermediate forwarding node. This has shown good results in comparison to the previous centralized solution where all data had to pass through a single server node. The new system has one master node that is responsible for registrations of both publishers and subscribers and distribute any necessary information to affected clients. This thesis has shown that the Single Point of Failure that was one of the main issues on the previous design has been removed and the performance of the system has increased as well. The Round Trip Time of a set of messages has shown to be improved up to 70.78%.
