Survey on Wireless Sensor Networks-Structure & Routing Protocols

Wireless Sensor Networks (WSN) are large collection of tiny nodes in order to gather information or to monitor the surrounding. The network formed with these set of nodes are organized into various manner. In order to provide a guaranteed service a periodic data collection of the environment is required and hence WSNs required to maximize network lifetime. The efficiency of WSN is strongly depends on routing protocols & other parameters like aggregation techniques, security. Variety of sensing capabilities results, sensor network usage in wide applications with most effective methods for data transmissions & processing.
