Bridge Wireless Sensor Network for Disaster Tolerance Technology

In NS2 network simulation, a bridge wireless ad hoc sensor monitoring network with 6kbps production from dynamic sensor nodes is examined. Three routing algorithm packet loss rates under different wireless bandwidths are analyzed using AODV, DODV, and DSR. The results show the following. With 1Mbps wireless bandwidth, the AODV routing algorithm is suitable for the bridge of small-scale wireless ad hoc sensor monitoring networks. To improve the capability of disaster tolerance, the sink node monitoring center needs to be used. With 2 Mbps wireless bandwidth, the performance of DSR routing algorithm is significantly better than other algorithms. With greater than 2 Mbps wireless bandwidth, the network bandwidth requires a two times larger flow of data as bandwidth increases, and the performance of the three routing algorithms is consistent.
