Reliable and efficient data gathering algorithms in wireless sensor networks

Abstract

People in our planet are very much interested in monitoring every entity in and around them In their peering action sensor networks are the one which are widely used in large numbers to monitor the environment in which physical parameters such as temperature sound vibration pressure motion and pollutants are measured with the aid of sensor networks Defense field has widely intensively employed sensor networks in battlefield surveillance The use of sensor networks have entered into many areas such as industrial process monitoring and control machine health monitoring, environment and habitat monitoring healthcare applications home automation and traffic control Sensor network is a type of ad hoc network which has no infrastructure at the bottom In a sensor network each sensor node can sense and collect the information Then the collected data is sent to the sink Data gathering is a broad research area in Wireless Sensor Network WSN The WSN considers the problem of communicating data between the base station and remote data sources via intermediate sensor nodes in a hierarchical sensor network
