Idea solution


Question 1:
What is the importance of IEEE 802.11b wireless network in developing MANET infrastructure?

Solution:
IEEE expanded on the original 802.11 standard in July 1999, creating the 802.11b specification. 802.11b supports bandwidth up to 11 Mbps, comparable to traditional Ethernet.
802.11b uses the same unregulated radio signaling frequency (2.4 GHz) as the original 802.11 standard. Vendors often prefer using these frequencies to lower their production costs. Being unregulated, 802.11b gear can incur interference from microwave ovens, cordless phones, and other appliances using the same 2.4 GHz range. However, by installing 802.11b gear a reasonable distance from other appliances, interference can easily be avoided.

Question 2:
How the forth generation of mobile wireless networks (4GM) can be implemented in the
modern military environment?

Solution:

Evaluation of wireless networks for performance evaluation is a popular research
area and a wealth of literature exists in this area. Wireless networks in infrastructure
mode as well as Ad-hoc networks such as MANETs are considered extensively.
Simulation results are provided for E-learning scenarios for cases where wireless
networks in infrastructure mode are employed, however the possibilities of using adhoc
networks and performance evaluation of e-learning scenarios with ad hoc
networks are not considered. This paper presents an evaluation of the performances
for wireless Ad-hoc networks employed in typical e-learning environment by using the
OPNET modeller. Numerical simulation results, discussions and comparisons are
provided. The results can be of great help for optimisation studies in typical e-learning
environments. The performance issues are considered together with scalability
concerns.

Question 3:
What are the major power challenges of 4G MANET?

Solution:

When processing speed doubles every 2 years, another significant component of

wireless devices limits their usage in the military environment - a battery. The forth generation of wireless technology offers increased bandwidth, mobility and the signal’s range. Increasing the signal power, a device requires more electrical power that will be consumed during signal transmission. The amount of energy currently stored in batteries needs to be increased to utterly benefit from the forth generation of mobile wireless network implementation. More sophisticated, with additional routing protocols and security enhanced, wireless nodes require also a lot of computational power. Although the processors speed increases and its they turn into lower power consumption by introducing nanometer processor technology, the software requirements become

more and more complicated requiring faster hardware and more electrical energy.

rechargeable or non-rechargeable batteries, which in result will decrease soldiers’ mobility. The solution for this problem can be new batteries designs and wireless

technology that will lower power consumption. Power aware microarchitecture, maximization of power efficiency, and management of heat, that is produced as a result of increased computational power, are issues that current chip leaders, like Intel, have to

consider while designing their products. Another solution for power constraints of mobile devices in military environment are coming up technologies such as designed by mPhase nanobatteries, which are disposable batteries. Nanobatteries’ revolutionary design uses “super hydrophobic characteristics of nanotexture circuses to control battery’s internal reaction“ and preserves energy for over 15 years by separating electrolyte from reactive

metal when are stored. Its small and flexible size supports nanobatteries candidacy for the military scenario implementation battery that will power up mobile 4G.
