... To the best of our knowledge there has been no research in the literature on customizing a method to ensure that the packet reaches a sleeping destination node. For that reason, a retransmission algorithm was already proposed [5] in combination with the sleeping mechanism. The aim of this algorithm is to increase the destination node's chances of receiving the packet if it is asleep when the packet reaches the destination zone. ...

Efficient Retransmission Algorithm for Ensuring Packet Delivery to Sleeping Destination Node
Self-configuring asynchronous sleeping in heterogeneous networks

ITU Journal on Future and Evolving Technologies

... In our proposed fine-grained sleeping mechanism [10], all the nodes have the same awake-sleep cycle, equal to T s . Inside the cycle, all the nodes have the same awake duration (or percentage of T s ), but the beginning of the awake interval is different for each node and is randomly determined. ...

Scaling up Routing in Nanonetworks with Asynchronous Node Sleeping

... With this in mind, we assume 64 bits as the frame size for high-priority events and 32 bits for low-priority events. In accordance with the related literature [17], [36]- [38], we assign a conservative nanonode symbol rate of 10 6 symbols per second. This means that in an On-Off keying modulation [36], typical for these environments and denoted as TS-OOK modulation, where one symbol equals one bit, the bitrate (R) is equal to 1 Mbps, and the value of t f is 64 µs and 32 µs, respectively. ...

Congestion Control by Deviation Routing in Electromagnetic Nanonetworks
  • Citing Conference Paper
  • September 2019

... For this reason, a flooding-based routing protocol is utilized in these types of intrabody nanonetworks where all the nanobots in the cohort receive all the transmitted packets. The main dis-advantage of the flooding-based routing protocols (even in optimized variants such as backoff-based flooding [35]) is the high number of re-transmissions which leads to faster nanobot energy depletion and increased packet loss. The different networking layers of a nanobot based on the OSI model are explained as follows. ...

Efficient Multi-Hop Broadcasting in Dense Nanonetworks
  • Citing Conference Paper
  • November 2018

... The probability needs to be tuned to prevent broadcast storms and guarantee message delivery. Backoff flooding is a highly efficient flooding scheme using a counter-based mechanism to count copies received, and adds a random waiting time (backoff) to packet forwarding [2]. The backoff window depends on the neighbor density. ...

Efficient Density Estimation Algorithm for Ultra Dense Wireless Networks
  • Citing Conference Paper
  • July 2018

... More recently, TeraSim [229] has been developed to simulate the THz communications for nanoscale scenarios in addition to the macroscale ones. Another recent electromagnetic nanonetwork simulation software, BitSimulator [230], can simulate nanonetworks with concurrent transmissions among numerous nano-devices to test coding, channel access, routing, and congestion control. Apart from the communication simulators, a 3D model [231] has also been developed, which provides a vessel model to expedite the research of in-vessel nanonetworks. ...

Bit simulator, an electromagnetic nanonetworks simulator
  • Citing Conference Paper
  • September 2018

... We started our study of this phenomenon by a second series of simulation, objective of which is to determine the ray of the zone of interference characterizing every node of network. In effect an experimental study [12] was led in this sense. Results concluded that in free space the zone of interference is nearly double the zone of communication. ...

Going for large scale with nano-wireless simulations

... Modular robots can use various application layer algorithms to enable specific functionalities and tasks [236]. However, the choice of these algorithms depends on what the modular robot system needs to accomplish, which may require combining and customising different algorithms to meet the application requirements to ensure efficient communication, coordination, decision-making, and task execution. ...
