Energy Efficient Data Aggregation of Wireless Sensor Network and Attacks using Error Bound

A wireless sensor networks (WSNs) consist of as many numbers of nodes which can communicate with each other. The sensor nodes consume energy during sensing, processing and transmission. In Wireless sensor network power and energy resources are limited. The number of sensor nodes is deployed in physical area. If each node sends information to the base station, energy is wasted and therefore the network energy are consume quickly. In this paper for data aggregation the READA technique will be used with some error bound. Redundancy Elimination for accurate data Aggregation (READA) uses a grouping and compression mechanism to get rid of duplicate information within the aggregated set of information to be sent to the base station. In wireless sensor network, security and energy efficiency issues are found. In this paper, different types of attacks associated with WSN and their effects are discussed.
