Comparative study of various voip applications in 802.11 a wireless network s...ijmnct
Today, Voice over Wireless Local Area Network (VOWLAN) is the most accepted Internet application.
There are a large number of literatures regarding the performance of various WLAN networks. Most of
them focus on simulations and modeling, but there are also some experiments with real networks. This
paper explains the comparison of performance of two different VOIP (Voice over Internet Protocol)
applications over the same IEEE 802.11a wireless network. Radio link standard 802.11a have maximum
transmission rate of 54Mbps. First protocol is session initiation protocol (SIP) and second is H.323
protocol. First one has an agent called SIP proxy. Second have a gateway reflects the characteristics of a
Switched Circuit Network (SCN). With this comparison we have required to obtain a better understanding
of wireless network suitability for voice communication in IP network.

WiMAX (Ver. 802.16e-2005) network scenarios. We also discuss about the various updates in
the Advanced Air Interface update (802.16m – 2011), which aims at fulfilling the 4G requirements as put forward by the ITU IMT-Advanced requirements.
Rm literature survey_on_scheduling_and_resource_allocation_for_ieee_80211ax_p...RESHAN FARAZ
IEEE 8021.11 is the standard defined for WLAN(Wireless Local Area Network). It first
came into the picture in 1997 which offer a speed of 2Mbit/s. After that we have different
versions, 802.11b having speed 11Mbit/s, 802.11a/g having 54 Mbit/s, 802.11n having 600
Mbit/s, and even above Gbit/s rates in the latest 802.11ac. These speeds can be achieved
by means of different modulation and coding scheme, wider channel and adaptation of
Multiple Input Multiple Output (MIMO) technologies[7]. The 802.11ax will provide outstanding average throughput in the dense environment. Many clients connect with the
Access Point (AP) simultaneously using the Orthogonal frequency-division multiple access
(OFDMA) where AP divides the entire frequency band into multiple subsets of orthogonal
sub carrier called as Resource Unit (RU),These RUs are assigned to different user to transit
in parallel which make 802.11ax different from all other versions of 802.11 so we need some
scheduling and resource allocation mechanism to utilize the features of 802.11ax. Before
going to scheduling and resource allocation, let us discuss some features of 802.11ax

Neuro-symbolic is not enough, we need neuro-*semantic*Frank van Harmelen
Neuro-symbolic (NeSy) AI is on the rise. However, simply machine learning on just any symbolic structure is not sufficient to really harvest the gains of NeSy. These will only be gained when the symbolic structures have an actual semantics. I give an operational definition of semantics as “predictable inference”.
All of this illustrated with link prediction over knowledge graphs, but the argument is general.

Epistemic Interaction - tuning interfaces to provide information for AI supportAlan Dix
Paper presented at SYNERGY workshop at AVI 2024, Genoa, Italy. 3rd June 2024
https://alandix.com/academic/papers/synergy2024-epistemic/
As machine learning integrates deeper into human-computer interactions, the concept of epistemic interaction emerges, aiming to refine these interactions to enhance system adaptability. This approach encourages minor, intentional adjustments in user behaviour to enrich the data available for system learning. This paper introduces epistemic interaction within the context of human-system communication, illustrating how deliberate interaction design can improve system understanding and adaptation. Through concrete examples, we demonstrate the potential of epistemic interaction to significantly advance human-computer interaction by leveraging intuitive human communication strategies to inform system design and functionality, offering a novel pathway for enriching user-system engagements.

Kubernetes & AI - Beauty and the Beast !?! @KCD Istanbul 2024Tobias Schneck
As AI technology is pushing into IT I was wondering myself, as an “infrastructure container kubernetes guy”, how get this fancy AI technology get managed from an infrastructure operational view? Is it possible to apply our lovely cloud native principals as well? What benefit’s both technologies could bring to each other?
Let me take this questions and provide you a short journey through existing deployment models and use cases for AI software. On practical examples, we discuss what cloud/on-premise strategy we may need for applying it to our own infrastructure to get it to work from an enterprise perspective. I want to give an overview about infrastructure requirements and technologies, what could be beneficial or limiting your AI use cases in an enterprise environment. An interactive Demo will give you some insides, what approaches I got already working for real.

2. 1 IEEE 802.11ah
is the WLAN standard
operating under sub 1GHz
frequency range (about 900MHz). It
is designed to extend range of
existing 11ac wifi network
operating in 2.4/5GHz as well as to
utilize the emerging opportunities
in IoT(Internet of Things) space.
It will also be used for
home automation, smart grid,
low power sensors and
wearable consumer electronic
devices.
supports completely new
PHY(Physical) layer and
MAC(Medium Access Control)
layer. These have been described
below. Following table-1 mentions
802.11ah frequencies supported in
different parts of the world.
It supports various bandwidths
viz. 1MHz, 2MHz, 4MHz, 8MHz and 16MHz.
Hence it is considered to be 10 times
downclocked version of IEEE 802.11ac
standard. Like other wifi network, 802.11ah
network also consists of 11ah AP(Access
Point) and 11ah compliant devices such as
water meter, power meter, Gas meter as
well as systems compliant to IEEE
802.11ah protocol stack.
3. It has higher
frequency range.
The IEEE 802.11 is
easy to installation.
The IEEE 802.11 has
reduced wiring
expense.
Simultaneously use of
equipment. It use also
unlicensed part of the
radio spectrum.
1 There are some important advantages of IEEE 802.11 are given below,
It is less cost
effective
It has efficient coding
technique..
4. 4 There are some disadvantages of IEEE 802.11 are given below,
7. In IEEE 802.11ah, the
extended range requirement is
fulfilled by introducing 1 MHz wide
transmission and by using a new
Modulation and Coding Scheme
(MCS) index (MCS10).
3 COVERAGE RANGE
8. The IEEE 802.11ah amendment is
intended to operate below 1 GHz which,
besides improved coverage, faces less
interference. This characteristic of the
IEEE 802.11ah appears particularly
attractive for IoT applications, where
hundreds or thousands of devices are
expected to coexist.
3 TIME AND FREQUENCY RESOURCES
12. In 802.11 system, an AP allocates an identifier called Association
IDentifier (AID), to each station during the association stage [15]. In a given
network, AID is a unique ID, through which the AP can indicate its associated
stations. The possible number of associated stations of an AP is up to 2,007 in
legacy 802.11 standard due to the limited length of the partial virtual bitmap of
Traffic Indication Map (TIM) Information Element (IE), where each bit indicates
the corresponding station’s AID.
4
13. with power saving mode, a station alternates between
awake state and doze state, where the station in doze state turns
off the radio components such that it cannot sense incoming
signals at all. When there are packets destined to a station in doze
state, the AP buffers the packets until the station wakes up and
requests the delivery of the buffered traffic.
4 POWER SAVING
14. To make the non-TIM stations’ traffic under control, 802.11ah
AP can let them wake up at a predefined time so that the wake-up time
of these non-TIM stations and their channel access attempts could be
temporally spread out. To exchange the wake up timing information
between AP and stations, 802.11ah has defined an IE called Target
Wake Time (TWT) IE, which is exchanged by association request and
association response frames. In TWT IE, there are four fields, i.e.,
request type, target wake time, minimum wake duration, and wake
interval mantissa, which are used to determine when and how often a
station wakes up for downlink and/or uplink transmissions.
4 CHANNEL ACCESS
15. A major deficiency of 802.11ah is its low data rates, and to overcome it,
there have been many efforts on throughput enhancements.
The first intention was to design more compact frame formats to reduce protocol
overheads, and correspondingly, a more compact MAC header format has been
proposed. Compares the proposed short MAC header format and the legacy
802.11 MAC header format. For the downlink, the address 1, which is destination
MAC address in the legacy MAC header, is replaced with the AID of the
destination station in the short MAC header format. Similarly, in the case of
uplink, the address 2, which is the MAC address of source station in the legacy
MAC header, is replaced with the AID of source station in the short MAC header.
In addition, in the short MAC header, the sequence control field is moved before
address 3 field. The address 3 field is optionally included in the short MAC
header and its inclusion is indicated by the indication bit in Frame Control (FC)
field.
