1 Introduction to the Wireless Sensor Network (WSN)

In recent times, advances in microelectronic mechanical systems (MEMS) and wireless communication technologies have led to the proliferation of wireless sensor networks (WSNs). A WSN can be broadly described as a network of nodes that makes a collaborative effort in sensing certain specified data around its periphery and thereby controls the surrounding environment. A typical sensor network consists of a large number of low-cost, low-powered sensor nodes that are deployable in harsh operating environments. Because of their varied applications in civilian and military ...
