Complex Adaptive WSNs for Polluted Environment Monitoring

The development of low cost, low power, multi-functional sensor nodes created a new form of networking applicable to a variety of fields. The goal is to create low cost, low power consumption and web accessed wireless sensor nodes in order to be used for environment monitoring. A wireless sensor network consists of large number of sensor nodes. One of these nodes is used as a gateway to be connected to the internet; this node is called a base station or a sink node. The capabilities of the gateway node will be larger than the other nodes in the system. However it will be directly connected to the internet via Wi-Fi or Ethernet adapter. Moreover a web server may be installed on this node; this will enable the system to be directly accessed any time from any location. The low power consumption is strongly needed to be used in A wireless sensor networks; this because the wireless sensor nodes almost powered by batteries. In order to achieve this goal an intelligent hardware and intelligent software should be implemented carefully to adapt the environment changes and do some adjustments and calibrations on the system.
