I’m planning to construct a Wireless Sensor Network which uses 18 Xbee 802.15.4 modules (17 as routers and 1 as broadcaster). The network will be configured as a star network configuration with the broadcaster sending out 50 messages/second to the other 17 routers (4 bytes/message). Therefore, it looks like the network throughput should be: 5048 = 1.6 kbps. Is everything considered realistic with Xbee 802.15.4?
These 18 Xbee modules are to be installed in the same room which size is 5m x 15m.
