Due to technology scaling, network-on-chip (NoC) become the viable solution for on-chip many-core systems. The most critical concern of NoC is congestion management caused due to heavy communication traffic between nodes. Without an appropriate congestion resolution strategy for reducing heavy in-network traffic, the efficiency of the entire network is damaged severely. In this paper, an interval based record-keeping mechanism is presented to reduce network traffic and congestion by maintaining a history table and previous packet transaction records at each node. Proposed method performs certain validity checks before allowing using previous transaction record from history table. The performance of the technique is investigated in terms of average delay and compared to the state-of-the-art routing algorithms using the Access Noxim simulator. The simulation results demonstrate that the proposed method has outperformed in terms of global average delay, with 8-12% improvement, the average number of hits is 26-61% greater than misses under different synthetic traffic. The proposed algorithm has been tested under various topological configurations for efficiency evaluations.

“…Fully adaptive routing indicates improvement in thermal distribution without performance degradation to lower the temperature and meet the performance specifications of high priority packets. A collaborative thermal-aware adaptive routing (CTTAR) scheme [4] to synchronize network traffic and thermal information is presented. Since unnecessary packet switching causes hotspots, the CTTAR first employs dynamic buffer change, which can restrict the routing resource around overheated regions to slow the rate of temperature increase based on expected thermal details.…”

“…Cooling mechanisms also known as heat sinks usually exist on only one side of the chip in multi-layer 3D NoC. Hence, layers further away from the heat sink have higher possibility of the thermal hotspots [4]. Due to these thermal hotspot difficulties and aggravation of failure mechanism puts an extra strain on cooling cost of the chip and reliability reduction in 3D NoC.…”

Network-on-Chip NoC based systems have severe thermal problems due to the stacking of dies and disproportionate cooling efficiency of different layers. While adaptive routing can help with thermal issues, current routing algorithms are either thermally imbalanced or suffer from traffic congestion. In this work a novel thermal aware dynamic weighted adaptive routing algorithm has been proposed that takes traffic and temperature information into account and prevents packets being routed across congested and thermally aggravated areas. Dynamic weighted model will consider parameters related to congestion and thermal issues and provide a balanced suitable approach according to the current scenario at each node. The efficiency of the proposed algorithm is analyzed and evaluated with state-of-the-art thermal-aware routing algorithms using a simulation environment. Results obtained from the simulation shows that the proposed algorithm has performed better in terms of global average delay with 17-33 percent improvement and better thermal profiling under various synthetic traffic conditions.
