A Multipath Energy Efficient Congestion Control Scheme for Wireless Sensor Network

Problem statement: In most of the existing works either detection of congestion or scheme for congestion control in wireless sensor networks are presented. A very few works have been done, taken in to account of both congestion detection and congestion control. In most of the congestion detection works they have not achieved accuracy in detecting congestion and have resulted with high latency time. Approach: In this study, we propose to design a multi-path energy efficient congestion control scheme to reduce the packet loss due to congestion. In our congestion detection approach, we follow a combined congestion estimation technique taking in to account on three main parameters specifically queue size, contention and traffic rate. For the congestion control, we design a rate control technique and a multipath routing protocol. Results and Conclusion: Simulation results show that our proposed approach achieves better throughput and packet delivery ratio with reduced delay, packet drop and energy.
