Wireless Sensor Networks (WSNs) are new generation of computer networks which have many potential applications and unique challenges. They usually consist of hundreds or thousands small sensor nodes such as MICA2, which operate autonomously; conditions such as cost, invisible deployment and many application domains, lead to small size and limited resources sensors. WSNs are susceptible to energy criterion and most of traditional networks architectures (i.e. Flat) are unusable on WSNs; due to count of existent sensor nodes, large-scale networks and their constraints.
