👋  Hey there, I'm Subathra - a Network Analytics Engineer at Eishaa Networks, want to learn, create, innovate and contribute. My principle is to never stop learning!

Network Analtics Engineer @Eishaa Networks, Chennai.

Low power design of Network on Chip

• Implemented conventional Network on Chip (NoC) with XY routing algorithm using SimEvents and Simulink toolboxes in Simulink.
• Designed and implemented NoC with a reduced number of routers.
• Implemented RTM routing algorithm for single layer NoC in Matlab code editor and imported to Simulink using SimEvents toolbox.
• Designed and implemented multi-layer NoC by creating a subsystem and using mask editor in Simulink.
• A routing table was introduced to externally store and access the destination router address from the spreadsheet to reduce the number of computations.
• A priority-based packet transmission was implemented using SimEvents and Simulink toolbox in Simulink.
• Created different test case scenarios to test the model and estimate packet delivery ratio and packet drop.
• A microstrip patch antenna was designed and its radio pattern is obtained for different frequencies using the antenna designer in MATLAB.
• Zigbee model was introduced inside the enhanced NOC model using communication, SimEvents, and Simulink toolbox in Simulink.

LTE-A for military applications

• Implemented an LTE single core network using INETv4.1.1 and LTE module in OMNET++.
• Different test case scenarios such as a network with high mobile nodes, static nodes, dense network, and so on were created to check the network performance.
• Modified the existing eNB module by adding UE and EPC modules in OMNET++.
• An algorithm was introduced to switch the eNB nodes between different states (isolated, meshed, vUE) based on the mobility of nodes and availability of the core network.
• Reviewed the model and fixed the issues raised during the integration of the module.
