Joint Congestion Control and Packet Scheduling in Wireless Sensor Network


Background: Congestion is the most important starting place for packet drop, escalating queuing delay, small throughput, retransmission of packets, and hence utilization of extra energy, also running down of communication resources. With the aim of surpassing this complication, Joint Congestion Control and Packet Scheduling (JCCPS) mechanism with the help of Space-Time Division Multiple Access (STDMA) is proposed in this research work. Methods: Here, an extended version which makes use of both cluster and tree based strategy is formulated. This builds a node-centric approach that makes a load balanced tree in WSNs of asymmetric structural design. Results: The proposed approach results in less congestion in the complete network, boosts the throughput and at the same time increases the packet delivery ratio (pdr) and also diminishes delay. Moreover, it also boosts network efficiency by the way of increased delivery of packets. Load balancing, network lifetime, and scalability are essential constraints for numerous data collecting sensor network applications. Furthermore, the proposed STDMA packet scheduling approach has enhanced working than the existing schedulers in accordance with the average task waiting time and end-to-end delay. Conclusion: The proposed JCCPS protocol is very effective to determine the constraints which influence the network.
