A survey of wireless sensor networks

Wireless sensor network is a special kind of Ad hoc networks and includes a set of small nodes which are able to sense their surroundings with a definite goal, information processing, storage, data exchange with other nodes and also the adjustability in response to the changes. Typically all the nodes are homogeneous and practically work together to achieve the overall goal of the network. The main goal in wireless sensor networks is to supervise and control the weather conditions and changes, physically or chemically, in an environment with a known limitation.
