Secure access is one of the fundamental problems in wireless mobile networks. Digital signature is a widely used technique to protect messages’ authenticity and nodes’ identities. From the practical perspective, to ensure the quality of services in wireless mobile networks, ideally the process of signature verification should introduce minimum delay. Batch cryptography technique is a powerful tool...
Glaucoma is an eye disease, where the elevated level of intraocular pressure (IOP) in the anterior chamber of the eye can damage the optic nerve causing irreversible blindness [1]. An IOP monitoring microsystem (IMM) implanted in the interior chamber of the eye is required to take frequent IOP measurements to account for its diurnal variation and dependency on the body posture, which is not possible...
Considering a system model of three nodes two-way relay channel with analog network coding, this paper discusses the optimal transmission power allocation problem to maximize the system achievable sum-rate. We propose an optimal transmission power allocation solution and show that our solution performs better than the uniform power allocation by numerical results.
To achieve better monitoring for small-scaled mobile robot, a real-time status monitoring platform is developed in this paper. The communication method between the MCU and the host computer is discussed and the formulation principles and rules of communication protocols are given. The main framework for the debugging software, the display measures of real-time monitoring data curves, and the insert...
Wireless power delivery to implantable biomedical devices by means of inductive coupling has been proved to be feasible. MEMS coils which are fabricated with micro-fabrication technology are used as the coupling coils. MEMS coils were formed by Cu electroplating with the thickness of 15μm. This paper present a new stack packaged MEMS coils which are helpful in improving the coupling efficiency. An...
