We present nanoNS3, a network simulator for modeling Bacterial Molecular Communication (BMC) networks. nanoNS3 is built atop the Network Simulator 3 (ns-3). nanoNS3 is designed to achieve the following goals: 1) accurately and realistically model real world BMC, 2) maintain high computational efficiency, 3) allow newly designed protocols to be implemented(More)
—LTE-A as a cellular technology has gained tremendous importance in recent years due to its high data-rates and improved data access for mobile devices. Recently, utilizing the unlicensed band as a supplementary band for LTE-A is being considered to expand the capacity of mobile systems. License-assisted access using LTE (LAA-LTE) will thus operate in the(More)
—In this work we consider nano-scale communication using bacterial populations as transceivers. We demonstrate using a microfluidic test-bed and a population of genetically engineered Escherichia coli bacteria serving as the communication receiver that a simple modulation like on-off keying (OOK) is indeed achievable, but suffers from very poor data-rates.(More)
In this work, we focus on the problem of source addressing in multiple source single receiver bacterial communication network. We propose amplitude-addressing, where the amplitude of transmitted signal is assigned as address of the source. We analyse the performance of the network with different addressing mechanisms and propose an optimum address sequence(More)
A group of 420 elderly people (163 women and 257 men with a mean age of 65 years) from urban and rural populations in India were selected for the study. The caloric intake of 93.3% was less than the recommended allowance, the mean daily caloric intake being 1191 kcal in men and 928 kcal in women. Except for calcium, all nutrients were deficient in their(More)
AIM To estimate bone mineral density and fracture threshold in South Indian elderly and to correlate BMD with risk factors. MATERIAL AND METHODS A prospective study of estimating bone mineral density (BMD) was done in 116 elderly patients from the out-patient Department of Geriatric Medicine, Government General Hospital, Chennai. Bone density was(More)
