A Wireless Sensor Network (WSN) is emerging field in Information and communication technology. In WSN data transmission and data collection are unsecure because of sensor node Incompatibility. So providing security to Sensor network is very important. The key based Mechanism is secure data collection and it's mainly used to guarantee data confidentiality. Range pair wise key is largely used due to the necessary of data encryption and decryption between each pair range of communication node. Fixed key mechanism difficult for the attacker to detect the regularity of the randomly generated key chain function in privacy homomorphism (PH).PH means no intermediate node to encrypt and decrypt only direct collect and aggregate data for encryption and decryption. It is special key based scheme. It's totally based on beta distribution and some statistical tool using key code method by using Complexity exchanging code key method addressing protocol. We show how to reduce significant attacks and secure data collection on wireless sensor network.

The Sensor Planning Service (SPS) is service model to define the web service interface for requesting user driven acquisitions and observation. It's defined by the Open Geospatial Consortium (OGC) Sensor Web Enablement (SWE) group to provide standardized interface for tasking sensors to allow to defining, checking, modifying and cancelling tasks of sensor and sensor data. The goal of Sensor Planning Service (SPS) of OGC - SWE is standardize the interoperability between a client and a server collection management environment. The Sensor Planning Service (SPS) is need to automate complex data flow in a large enterprises that are depend on live & stored data from sensors and multimedia equipment. The obstacle are faced in Sensor Planning Service (SPS) are (I) Observation from sensor at the right time and right place will be problem, (II) acquisition information(data) that are collected at a specific time and specific place will be problem. The above two obstacle are accomplished and obtained by the web based semantic technology in order to provide & apply the ontology based semantic rule to user driven a acquisitions and observation of Sensor Planning Service (SPS). The novelty of our approach is by adding the semantic rule to Sensor Planning Service model in SWE and we implemented Sensor Planning Service (SPS) with semantic knowledge based to achieve high standardized service model for Sensor Planning Service (SPS) of OGC - SWE.
