Wireless Communication, MAC Protocol,
In recent times, the wireless networks have become
very popular. Wireless LANs are being deployed on
airports, conferences, etc. People have started using
portable laptops to access Internet and other resources
using wireless networks while moving. Another

The intermediate stations are called relaying stations.

mitigate the above problem additional control packets,
request-to-send and clear-to-send control frames, are
transmitted prior to the exchange of the actual data
frame. A successful exchange of these control packets
ensures that channel is reserved for the time period
enough to complete the data transfer process.

DCF
The DCF is the fundamental access method used to
support asynchronous data transfer on a
basis. The DCF is based on CSMA/CA. The carrier
sense is performed at both the air interface, referred to
as physical carrier sensing, and at the MAC sub layer,
referred to as virtual carrier sensing. Physical carrier
sensing detects presence of other users by analyzing
the activity in the channel through the received signal
strength. A station performs virtual carrier sense by
examining the received MPDU (MAC Protocol Data
Unit) information in the header of RTS, CTS and
ACK frames. The stations in BSS use this information
to adjust their Network Allocation Vector (NAV),
which indicates amount of time that must elapse until
the current transmission is complete and the channel
can be sampled again for idle status. Priority access to
the medium is controlled through the use of
mandatory inter frame space (IFS) time intervals
between the transmissions of frames. Three IFS
intervals are specified in the standard: Short IFS
(SIFS), PCF-IFS (PIFS), and DCF-ISF (DISF).
PCF
The 802.11 MAC offers contention free service by
means of PCF. PCF is optional capability and
provides contention-free (CF) frame transfers. The
PCF relies on the point coordinator (PC) to poll other
stations. The polled stations can send the data without
contending for the medium. In a wireless LAN, the
function of a PC is performed by AP within each
BSS. The PCF is required to coexist with the DCF
and logically sits on the top of DCF (see Figure 3.4).
The PCF consists of alternating contention free period
(CFP), and contention period (CP) as shown in figure
3.6. In the CFP, the PC polls each of the stations
present in the BSS. The PC specifies the start of the
CFP by sending a beacon that contains the length of
CFP duration, among other things. All the sta

CFP by sending a beacon that contains the length of
CFP duration, among other things. All the stations in
the BSS set their NAV for the duration of the CFP.
The PC terminates the CFP by sending a CF
frame, and may also terminate it before the advertised
CFP duration. The time difference between two
beacons is called beacon period (BP) or CFP
repetition interval, and is a multiple of beacon frame.
The beacon also helps in synchronization and timing.
The limits on durations of each of the frames are
described in the IEEE 802.11 standard [5]. In the CP,
the stations use DCF to access the medium.
2. Ieee 802.11 Mac Protocol Operation
The IEEE 802.11 MAC offers two kinds of medium
access methods, namely Distributed Coordination
Function (DCF), and Point Coordination Function
(PCF). DCF is the basic access method in 802.11 and
requires no infrastructure. Wh

Service Set (BSS), and can communicate to each
other using DCF. If the BSS contains only two
stations, it is called Independent Basic Service Set
(IBSS). Many BSSs may be conne

Service Set (ESS). An access point (AP) is the station
that provides access to DS services. The PCF is built
on the top of the DCF, and is also referred to as
infrastructure mode. It requires a polling
Point Coordinator (PC), which acts as controlling
station during poll. The PCF consists of alternating
Contention Free Periods (CFP) and Contention
Periods (CP). During CFP, the PC polls other stations
in the medium, and during CP, the acce

The PC terminates the CFP by sending a CF-End

802.11 Mac Protocol Operation
The IEEE 802.11 MAC offers two kinds of medium
access methods, namely Distributed Coordination
Function (DCF), and Point Coordination Function
(PCF). DCF is the basic access method in 802.11 and
requires no infrastructure. When wireless stations are
within transmit range of each other, they form a Basic
Service Set (BSS), and can communicate to each
other using DCF. If the BSS contains only two
stations, it is called Independent Basic Service Set
(IBSS). Many BSSs may be connected by a
Distribution System (DS) to form an Extended
Service Set (ESS). An access point (AP) is the station
that provides access to DS services. The PCF is built
on the top of the DCF, and is also referred to as
infrastructure mode. It requires a polling station called
Point Coordinator (PC), which acts as controlling
station during poll. The PCF consists of alternating

Figure 3: Multihop Scenario
Consider a multihop centralized scenario, as shown in
the figure 3.For convenience; the stations inside the
network are classified into following categories:
Central station is the central controlling station. Most
of the traffic in the network is directed towards it.
Inner stations are within one hop boundary of the
central station. Boundary stations are at one hop
boundary of the central station. These stations act as
relaying stations for the stations outside the reach of
central node. Outer stations are outside the
communication range of central node.

The 802.11 MAC with DCF mode of operation is the
simplest choice in multihop ad-hoc networks. The
reason for the choice of DCF is that it does n

and its one hop neighbors is very high. Since the DCF

badly in high load conditions. The poor performance

more and more stations try to access the medium at

[8] have shown that the PCF
mode performs better than DCF when the number of
stations in WLAN cell is very high. Therefore, we
make the central node as Point Coordinator (PC), and
it polls all the inner and boundary nodes during CFP
period. This differs from conventional PCF operation
in WLANs where PC resides within AP. The outer
stations still perform DCF since the traffic in those
regions is not high. The outer stations can send their
data in contention period (CP) as all the stations
perform DCF during CP. We refer this combination of
PCF and DCF as hybrid operation as shown in
4.
The hybrid operation seems to be an ideal choice in
multihop networks, but it gives rise to following
problems:
The stations that are polled by the Point Coordinator
(PC) keep their NAV set during the CFP period, and
therefore, cannot receive from outer stations. It can
also be said that the boundary nodes become exposed
to PC.
Figure 4 Hybrid PCF-
Outer stations become hidden to PC, and vice versa,
as there is no RTS/CTS exchange between PC and its
one hop neighbors during CFP period.
Problem Description
Simple DCF is not suitable for centralized multihop
network due to collisions at high traffic.
MAC (PCF) is required at the centre of the network to
handle high traffic and reduce collision, but it gives
rise to hidden and exposed node problems. The
solution to both of these problems is provided by
introducing dual Nodes at the boundary of

MAC should be able to receive even if its NAV is

not collide with that of PC at boundary stations.
To address above problems, we propose to equip
boundary stations with dual MAC. A dual node is
a station which has two independent MACs each
communicating on different logical channels. The
two MACs are encapsulated inside the dual MAC.
The logical channels could be FDMA or CDMA.

MACs uses the PCF and is termed as PCF MAC.
The second MAC uses the DCF and is termed as
DCF MAC. The PCF MAC communicates with
the PC, and the DCF MAC communicates with
the outer nodes. The exposed and hidden node
problems in central region are eliminated as
follows:
 Boundary stations use the PCF and the DCF on
different channels. Therefore, the transmission of
outer node does not collide with that of PC, and
vice versa.
 The DCF MAC in the dual node can receive from
outer nodes even when the NAV of PCF MAC is
set during CFP period, thereby eliminating
exposed node problem.

5. CONCLUSION
The results show that the dual MAC performs
reasonably better than the DCF access mechanism.
However, the dual MAC requires two physical radios
and two separate channels –
another to DCF. We may however, note that the
throughput gain is worth the cost of dual MACs since
only few nodes need to be equipped with dual MAC.
The main focus of this thesis is to suggest a
modification to the existing IEEE 802.11 MAC so as
to make it suitable in multihop ad
especially in the real life centralized networks. The
results presented in the thesis are applicable for static
scenario, nevertheless, the dual MAC is expected to
perform better even under mobile scenario. The effect
of mobility on performance of dual MAC still remains
to be seen.
