Design of Wireless Nanosensor Networks for Intrabody Application
Emerging nanotechnology presents great potential to change human society. Nanoscale devices are able to be included with Internet. This new communication paradigm, referred to as Internet of Nanothings (IoNT), demands very short-range connections among nanoscale devices. IoNT raises many challenges to realize it. Current network protocols and techniques may not be directly applied to communicate with nanosensors. Due to the very limited capability of nanodevices, the devices must have simple communication and simple medium sharing mechanism in order to collect the data effectively from nanosensors. Moreover, nanosensors may be deployed at organs of the human body, and they may produce large data. In this process, the data transmission from nanosensors to gateway should be controlled from the energy efficiency point of view. In this paper, we propose a wireless nanosensor network (WNSN) at the nanoscale that would be useful for intrabody disease detection. The proposed conceptual network model is based on On-Off Keying (OOK) protocol and TDMA framework. The model assumes hexagonal cell-based nanosensors deployed in cylindrical shape 3D hexagonal pole. We also present in this paper the analysis of the data transmission efficiency, for the various combinations of transmission methods, exploiting hybrid, direct, and multi-hop methods.
THE family of a black immigrant has blasted his death as a “modern-day lynching” after he was shot dead while allegedly on a hunting trip with five white men.
Peter Spencer, 29, was reportedly shot at least nine times earlier this month as the men with him claim they acted in “self-defense,” his family says.
He had been dropped to a cabin in Venango County, Pennsylvania, in the afternoon of December 11 by his pregnant fiancee Carmela King who said she received a text shortly afterward to say he was staying the night.
At 2.30am on December 12, police were called to the cabin on Carls Road and found Peter dead at the scene.
A 25-year-old-man was taken into custody but Pennsylvania State Police provided no further details when contacted by The US Sun.
Multiple guns were also reportedly found at the scene but no charges have been filed.
“We are talking six bullets into the chest, two into the buttocks, and one we have a different opinion – either through the mouth or from the neck out of the mouth,” Tim Stevens, CEO of the Black Political Empowerment Project, alleged to WTAE.
Peter, who was originally from Jamacia, had reportedly been contacted by a man he used to work with on Snapchat about the hunting trip.
The man allegedly brought along his own friends as well, two GoFundMe pages set up by the family said.
“This time he was taken directly into the woods and not this person’s mother’s home … to the fiancé she didn’t totally feel comfortable with that,” Stevens said of Peter’s arrival at the cabin.
Peter’s brother Tehilah Spencer claimed on a fundraising page that the 29-year-old was “murdered in cold blood.”
