1 1 Aggregated Traffic Flow Weight Controlled Hierarchical MAC Protocol for Wireless Sensor Networks Asia FI School Presented By Md. Abdur Razzaque Kyung Hee University Global Campus, South Korea

2 2 Contents Introduction Proposed Traffic Model Proposed ATW-HMAC Protocol Analytical Analysis Conclusion

3 3 Introduction S-MAC, TRAMA, T-MAC, FLAMA saves significant amount of energy by periodically switching off the nodes to low power mode. They save energy at the cost of throughput and end-to- end packet delay. Incurs a great amount of energy overhead due to: clock synchronization, schedule message passing, waking up the radio periodically. Works fine in very low data rate networks. How to design an energy-efficient MAC protocol that greatly minimizes the network congestion while maximizing the achievable data delivery rate? Supports multiple application types. Supports both multi-path and single-path network.

4 4 Traffic Model

5 5 Determination of CW min Values Single-path routingMulti-path routing Both the events are of type AEvent 1 is B type and event 2 is A type Both the events are of type AEvent 1 is B type and event 2 is A type Node ID

6 6 Analytical Analysis Weighted Fair Rate Allocation: Energy Consumption Analysis:

7 7 Conclusion Next problem to address: How to further increase the overall throughput whenever data packets from a single source node are routed over multiple paths by employing a dynamic traffic engineering algorithm.
