Wireless Sensor Network is an adhoc network of tiny sensors. Each sensor is defined with some energy. As the data is transferred over the network each sensor spends some energy and cost in sending, receiving and forwarding data. Network life depends on how much energy and cost spends in each transmission. Opportunistic routing has been shown to improve the network throughput, by allowing nodes that overhear the transmission and closer to the destination to participate in forwarding packets, i.e., in forwarder list. WSN basically refers to the exploitation and management of data created by the environment of WSN that is usually of very demanding nature, given the huge amount of data being transformed on the basis of real time by a wide number of WSN based Things, which are interlinked on a worldwide scale via the Internet. Moreover, this kind of data is usually imperfect and heterogeneous as they originate from distinct type of sources, which are mainly sampled using a hardware i.e. of low-cost, and are carried over the communication links of unreliable nature. To enable an effective and seamless integration of such a dynamically changing, wide-volume, imperfect, distributed, and heterogeneous data into the applications and services of valuable form, plans are needed to preprocess and clean the data, in order to provide real time data analytics and in a fashion of distributed form, to serve the informational data in a standard form such that it can be reused easily, to search and index the data on the basis of its content or description, and to provide data storage in a scalable form along with its management..
