2. Environment Monitoring System
Environmental monitoring has been an important part of Wireless Sensor Network applications. It grows widely along
with the development of recent technology. In general, environmental monitoring system controls and monitors
environment parameters such as temperature, humidity, light and pressure.
There are several studies that focus in environmental monitoring applications [4][5]. Some researchers implement the fault
tolerant and studies the tradeoff between tool expense and lifetime of sensor network [6] to make sure the fault tolerance is
in the three dimensional settings.[7] and [8] developed multi hop communication applications, which means the data of the
temperature and humidity will be transmitted to the neighbour node and then sent to the end user PC. The environmental
parameter data measurement will display the result using Java [3] and the data are interpreted into a graph and table.
Thus, it is necessary to understand the requirements for the development of monitoring applications [9].
2.1 Autonomy
It is compulsory to make sure the battery used is able to function properly throughout the deployment because the radio
transceiver is a solid energy consumer and the network must be energy-wise.
2.2 Reliability
Simple handling and predictable operations are needed in order to avoid unexpected crashes system. Besides, maintenance
by any person should be avoided because the end users may lack the knowledge on networking and also the changes on the
area of interest that often happens while transmitting the packet data. Therefore, it is important to achieve reliability in order
to prevent packet loss during bad weather conditions.
2.3 Robustness
The network has to be robust to encounter problems such as hardware failure and poor signal connectivity. For example,
the effect of humidity can bring short circuit problem and lead to system reboot.
