3、he following Fig. 2 shows the block diagram of the wireless sensor node.Fig. 2 Block diagram of Zigbee based wireless sensor nodeThe main microprocessor of the sensor node is based on the Zigbee compliance product from C

4、irronet. The high power transmission type ZMN2405HP Zigbee module is using the CC2430 transceiver IC from Texas Instrument comply to the IEEE 802.15.4 standards with a maximum transmission power of 100 mW using the dipol

5、e antenna and 250 mW using the directional patch antenna. The transceiver IC is integrated with the 8051 microcontroller with a low power but high performance of 64 kByte programmable flash features. The module alone req

6、uires a 5VDC power supply, multiple sensor inputs/outputs with ADC, operating at a frequency of 2.4 GHz with a configurable sleep mode to get the best of power consumption as low as 3uA [5].The main microcontroller in th

7、e module is reprogrammable whether to function as an end device, router or coordinator nodes. As an end device sensor node, it can only communicate with the router or coordinator to pass the data from the sensor. An end

8、device can only communicate indirectly with the other end device through the router or coordinator. The sensor node defined as a router is responsible for routing data from other routers or end device to the coordinator

9、or to other routers closer to the coordinator. The router can also be a data input device like the end device but in actual application it is generally used to extended the coverage distance of the monitoring system. The

10、re can be only one coordinator for the monitoring system. The coordinator responsible for setting the channel for the network to use, assigning network address to routers and end devices and keeping the routing tables fo
