Wireless Sensor Networks (WSNs) with large number of sensor nodes are used to monitor the sensing filed.Sensor node energy efficiency and sensor network data-transfer reliability are the primary design parameters.Some applications may require heterogeneous sensor nodes with different sensed phenomena and different hardware characteristics.This heterogeneity imposes an added constraint to the mining of useful information from the network.At the same time, a stream of data that is frequently reported from each node to the base station or sink may be needed.In this paper we are considering multi-feature sensor network where the sensors are having ability to measure more than one phenomenon.Our focus is on developing a new clustering algorithm that handles the concept of multi-feature sensor networks.Sensor nodes in WSN are based on energy, minimizing energy consumption is an important issue in WSN.Data mining in such multi-feature sensor network is also another important issue.As the existing LEACH protocol, the protocol used for clustering, is having drawbacks with respect to energy consumption.We are building new improved or modified LEACH communication protocol that consumes less energy compared with the existing one.
