ENERGY-EFFICIENT CLUSTER BASED ARCHITECTURE DESIGN FOR WIRELESS SENSOR NETWORKS

Sensor networks are unlike other forms of networks in a variety of ways with respect
to their various functionalities in the sense that they are severely hampered by
inadequate local resources such as battery power, storage and the dependability of
each node. These networks usually consist of cheap, unreliable nodes. Due to these
properties, the efficient collaboration among individual nodes which is essential for
the successful completion of the overall network task might be lacking. Moreover,
efficient collaboration is necessary for providing services such as information
processing, message transmission, maximizing network lifetime and for the reduction
of propagation delay. There are several network design parameters which have a
tremendous impact on the lifetime of the network; among these parameters are
latency, routing and energy efficient techniques. These are the most important ones
because in some critical application areas a quick response may be necessary and an
accurate form of the data must be received by the end user.
