Methods for attaching radio transmitters to rock iguanas (genus Cyclura) are described and compared based on signal range, longevity of attachment, and potential disturbance to animal behavior or health. Case studies are described for all instances of internal implantation, ingestion, and external attachment of transmitters for which data are available. Signal range did not differ dramatically ...

We study the role of caches in wireless interference networks. We focus on content caching and delivery across a Gaussian interference network, where both transmitters and receivers are equipped with caches. We provide a constant-factor approximation of the system’s degrees of freedom (DoF), for arbitrary number of transmitters, number of receivers, content library size, receiver cache size, an...

Problem statement: Power consumption was one of the most challenging aspects to design low power wireless sensor nodes. The objectives of the study were to (i) Design low voltage, low power transmitters for wireless sensor nodes and (ii) Compare and analyze the performance of the transmitters. Approach: The transmitters employed direct digital modulation scheme to reduce the power consumption o...

We consider a cognitive radio network in which a multiple-access secondary system coexists with an automatic repeat request (ARQ)-based primary system under heavy primary traffic. To achieve spectrum sharing without degrading the performance of the primary system, the secondary transmitters alternate between cooperation and access modes based on a credit system. In the cooperation mode, the sec...

The deep dorsal horn represents a major site for the integration of spinal sensory information. The bulbospinal monoamine transmitters, released from serotonergic, noradrenergic, and dopaminergic systems, exert modulatory control over spinal sensory systems as does acetylcholine, an intrinsic spinal cord biogenic amine transmitter. Whole cell recordings of deep dorsal horn neurons in the rat sp...

This paper develops a stochastic geometry-based approach for the modeling and analysis of singleand multi-cluster wireless networks. We first define finite homogeneous Poisson point processes to model the number and locations of the transmitters in a confined region as a single-cluster wireless network. We study the coverage probability for a reference receiver for two strategies; closest-selec...

Molecular communication is the process of transmitting information by modulating the concentration of molecules over time. Molecular communication is suitable for autonomous nanomachines which are limited in size and capability and for interfacing with biological systems which perform functions controlled or influenced by molecules. Some functions may require nanomachines to perform sequential ...
