Hybrid sensor network with high throughput and fairness
Xuming Fang · Journal of Computer Applications · 2010
Though the higher transmission rate and fairness are demanded in Wireless Sensor Netwoks (WSNs), it is hard to enhance the network throughput and fairness due to the constraints of WSNs. However, inspired by some special scenarios in practice, Hybrid Sensor Networks (HSNs) can be designed to make up the drawbacks in the deployment of WSNs. In this paper an optimal throughput allocation mechanism for fixed sensor network was proposed, and then three heuristic algorithms that were called greedy algorithm, K-increment clustering algorithm and hybrid algorithm for the wire deployment problem were presented. The simulation results show that the hybrid algorithm, which performs best among these three algorithms, achieves up to 75% improvement on minimum node throughput in the network. Therefore, the whole network performance could be significantly improved.
