EFFICIENT AND SECURE DATA TRANSMISSION IN WIRELESS SENSOR NETWORKS

Abstract

Communication based on wireless sensor networks happens across a wireless channel. There are numerous users in a large area, for instance, mobile users. Numerous towers in the local vicinity serve as nodes, or sensors, in wireless sensor networks. Thus, communication takes place between nodes without the need for a physical connection. In other words, data is transmitted from a transmitter node to a sink node, which connects to an external base station or to each other via a large number of intermediary nodes.  Numerous nodes make up a network, with one serving as a source node and one or more serving as a destination node. Wireless sensor networks have the benefit of operating unattended in severe environments, where manual human monitoring methods are unsafe and ineffective.
