Routing Driven Key Management Scheme for Heterogeneous Sensor Networks
The many-to-one traffic pattern dominates in sensor networks, where a large number of sensor nodes send data to one sink. A sensor node may only communicate with a small portion of its neighbors. Most existing key management schemes for sensor networks are designed to establish shared keys for all pairs of neighbor sensors, no matter […]
An Efficient Key Management Scheme based on Elliptic Curve Signcryption for Heterogeneous Wireless Sensor Networks
an efficient key management scheme based on public key elliptic curves signcryption scheme for Heterogeneous sensor networks has been proposed. The proposed protocol is optimized for cluster sensor networks and is efficient in terms of complexity, number of message exchange, computation, and storage requirements with optimized security benefits for clustered environment. The proposed key management […]
Software Design of Beam Steering of a Phased Array Radar
A software design and its’ hardware platform of beam steering of a active phased array radar is presented in the paper. In this design, FPGA (Field－Programmable Gate Array) is adopted to realize the core algorithm and Single Chip Microcomputer (SCM) is used as the heart of control and adjustment of array module-drive board. A control […]
