4.1 Simulation Environment

Our radio model uses characteristics similar to Telosb interface
and using ad hoc routing. Telosb uses CC2420 chip [cc2420chipcon]
, supporting eight different transmission power levels. Energy
consumptions for different transmission power levels are shown in
Table [tab:Telosb-Transmission-Power]. To simulate the typical
Telosb energy model in NS-2, we calculate the energy consumption
by each power level, given by: E=Pt, where power is the product
of the voltage and current drained at particular power level (P=VI
). Table [tab:Simulation-parameter-settings] shows our simulation

Simulation Parameter Settings

| Parameter | Value |
| Channel carrier frequency | 2450 MHz |
| Data packet size | 25 bytes |
| Data rate | 12 kbps |
| RXthresh_ | -94 dB |
| Max Queue length | Large enough to avoid any drops |

In this paper, a new approach to transmission power control was
presented for multihop and single hop WSNs. While some
researchers have suggested that short-range multihop
communication can extend sensor node's lifespan, our results,
both numerical analysis and simulation, show that this is not the
case. We have shown that if the distance between source and
destination is fixed, then the total energy consumption in the
WSN increases as we increase the number of hops and reduce the
transmission power for each hop. The difference between our
results and the published literature is due to the fact that we
consider all components of energy consumption and not just the
component related to the radiating power from antennas.
Furthermore, we provide an effective approach to test TPC in
multihop communication at the physical layer.

Quantifying the End-to-End Delay Performance in Multihop Wireless Networks

- This project uses a window based flow control and rate based scheduling algorithm for multihop wireless networks with fixed-route flows operated under a general interference model with interference degree. The proposed algorithm not only achieves a provable throughput guarantee, but also leads to explicit upper bounds on the end-to-end delay of every flow. The end-to-end delay and throughput bounds are in simple and closed forms, and they explicitly quantify the tradeoff between throughput and delay of every flow....   [tags: multihop wireless, wireless networks, throughput]

New Approach to Education System Essay

- Lots of people have a transformative influence on people’s lives. This can be achieved with different ways; education is one of these ways. From Aristotle to today’s world, lots of people have been contributing big impacts on education system which has big effect on people’s personality and lives. Anne Sullivan, William McGuffey, Emma Willard, and Maria Montessori all great teachers who did their work very well and they had a profound impact on the lives of innumerable people. In today’s world lots of students, teachers, and parents think that Montessori education system is much successful than traditional education system....   [tags: montessori, self-control, pedagogical methods]

Essay on No Control of Happiness in Brave New World

- Brave New World, acknowledges government control which results in the failure of a society. It is a world created where everything is under control, being observed, and synthetic. The society was manufactured in a test tube therefore, it was factory made. The people were born and developed in the test tubes, so their human nature became adapted so an individual cannot identify or approach it. Every little detail of a person's life is prearranged. These people's lives revolve around their community, their existence, and security; never their individual happiness....   [tags: Brave New World Essays]

High Performance Architecture for IP Based Multihop Networks Essay

- High performance Architecture for IP based multihop 802.11 Networks The concept of a forwarding node, which receives packets from upstream nodes and then transmits these packets to downstream nodes, is a key element of any multihop network, wired or wireless. While high-speed IP router architectures have been extensively studied for wired networks, the concept of a “wireless IP router” has not been addressed so far. This article provides all the problems and methods for increasing the throughput in multihop networks by changing the MAC layer and enhancing it with IP packet forwarding and routing....   [tags: computer technology]

A New Quality Control System Essay

- Change can be difficult in many situations because it is easy to get complacent and stuck in our ways. In a corporate setting change can be even more difficult. On a corporate level change will involve many people, many departments, and even a whole corporate culture. In the case of John Smithers he was asked to implement a new quality control system for the company he worked for. In the end the program never gained any traction and John felt his days were numbered because some staff changes were already being made....   [tags: Emotion, Management, Quality control, Starbucks]

Tobacco Control Of New Zealand Essay

- Health promotion is all about improving everyone’s health, an important health issue to date is tobacco control in New Zealand. Smoking is not only dangerous for those who smoke, as 5000 people die each year due to second hand-smoke (MOH, 2014). A survey taken in 2011 by the Ministry of Health showed that Maori continue to have high smoking rates at 41 percent and that two in five are smoking. The high percentage of smokers is strongly correlated to the low socioeconomic status of most Maori’s throughout New Zealand....   [tags: New Zealand, Health care, Indigenous Australians]

- Fig. 1 and Fig. 2 show energy per packet consumed as we increase the number of hops for both radiating and electronic parts respectively. These results were obtained using our derived numerical model. Fig. 3 shows numerical and simulation results obtained for average energy (radiating and electronic) per packet consumed as we increase the number of hops. The percentage of energy storage spent by each individual node as we increase the number hops is shown in Fig. 4. The x-axis label shows each individual node, where SNK, S and R denote sink node, source node and relaying node respectively....   [tags: Electrical Engineering]

Rent Control: Pros And Cons Essay example

- Rent Control: Pros and Cons Rent control is the government imposition of price ceilings on rent for apartments in certain areas of a city. The goal is usually to protect the rights of the poor. Thus, in a rent controlled or rent stabilized building, the amount of rent will not increase as quickly as inflation. While the moral side of rent control may have some appeal, in the long run the disadvantages far outweigh the advantages. Those who argue in favor of rent control say that it is the only way to protect lower-income tenants from landlords who overprice, and from being forced to move out of a neighborhood because they cannot afford the rent....   [tags: Rent Control New York Argumentative Essays]

Brave New World: Out of Control Essay

- Brave New World: Out of Control In the 1932 satirical novel Brave New World, Aldous Huxley describes an emotionless, mechanized world of the future, set mostly in London, in which individuality is eliminated, creativity is stifled, and such institutions as marriage, family, and church are unpleasant artifacts of a world long gone. In this society, people are mass-produced; human eggs are artificially engineered by technicians. Happiness is achieved through physical gratification and peace is safeguarded by the conditioning of youth and by dispensing soma, a tranquilizer....   [tags: Brave New World]
