Enhancing the Performance of Wireless Sensor Networks Using Aggregation Tree Model

As the scale of the network increases, especially wireless sensor networks comes into fashion, the problem of enhancing the performance of the networks turns into a focus topic. When network information changes, frequent route computing and network state updates can cause computing and traffic overhead, respectively. A novel protocol, which is based on aggregation tree routing model (ATRM) is used in this paper, which aims to minimize the alteration of network topology with virtual multiple-input-multiple-output and to minimize the end-to-end delay. The simulation results show that our protocol not only results in significantly lower overhead, but also gives higher levels of network performance.
