To improve Security enhancement and Lifetime Management Scheme for Wireless Sensor Networks

چکیده
Environment monitoring is one of the complex tasks in any industry. Sensor devices are used to handle the environment monitoring operations. Temperature, the sensor devices observe pressure and humidity values. The sensor networks are constructed with sensor devices. Battery power and bandwidth are the main limitations of the sensor networks. Managing the node lifetime and network lifetime are the complex task in the sensor networks. The data security is the most crucial task in the sensor network data transmission process. Scheduling schemes are used to increase the lifetime of the node and network. Lifetime based scheduling model is used in the existing schemes. Homogeneous and heterogeneous lifetime based models are used to increase the lifetime of the sensor networks. Same battery power is used in all nodes under the homogeneous environment. Heterogeneous environment uses the nodes with different battery power. The scheduling scheme manages the network connectivity and path switching operations. The coverage and lifetime models are integrated in the lifetime management scheme. The homogeneous coverage uses the node with same coverage distance for all nodes. The heterogeneous coverage manages the nodes with different coverage distance values. The system is designed with the sleep-wakeup scheduling algorithm. The path switching is carried out to transfer the data values from the node to the sink node. The system reduces the path switching frequency. The network lifetime is increased in a considerable manner. The data security is provided using the RC4 (Rivest Cipher) algorithm.
