CBR – Component Based Routing · In this project system engineering techniques are applied to the development of optimal routing protocols for mobile ad hoc networks. · Decomposition of known Routing Protocols into components. · Study, both by analysis and simulation, the impact of each component to the overall performance of the Routing Protocol. · Determine optimal component versions for different types of networks. · This project is a subtask of the U.S. Army Research Laboratory (ARL) Collaborative Technology Alliance (CTA) in Communications and Networking in collaboration with top research organizations from industry and academy. · I am involved in the modeling of performance of various component versions and in the development of Software Applications to incorporate the component models designed by all the involved institutions. Signal Processing for Cross-Layer Congestion Control · Development of a network congestion control mechanism that maximizes the data throughput and at the same time guarantees a fair distribution of bandwidth among all of the nodes in the network. · This mechanism permits the coexistence of multiple data flows in an ad hoc network, by controlling congestion as a cooperative effort of the nodes in the congested region. · The developed scheme significantly outperforms current control mechanisms. · The algorithm extends the concept of AQM (Active Queue Management) to Wireless Networks that use 802.11 DCF as their MAC protocol. · This project was also a subtask of the U.S. Army Research Laboratory (ARL) Collaborative Technology Alliance (CTA). · I was involved with the design of the algorithm as well as the design and implementation of the simulation experiments to test the proposed algorithm. |
