A Study on False Channel Condition Reporting Attacks in Wireless Networks
ABSTRACT:
Wireless
networking protocols are increasingly being designed to exploit a user’s
measured channel condition; we call such protocols channel-aware. Each user
reports the measured channel condition to a manager of wireless resources and a
channel-aware protocol uses these reports to determine how resources are
allocated to users. In a channel-aware protocol, each user’s reported channel
condition affects the performance of every other user. The deployment of
channel-aware protocols increases the risks posed by false channel-condition
feedback. In this paper, we study what happens in the presence of an attacker
that falsely reports its channel condition. We perform case studies on
channel-aware network protocols to understand how an attack can use false
feedback and how much the attack can affect network performance. The results of
the case studies show that we need a secure channel condition estimation
algorithm to fundamentally defend against the channel-condition misreporting
attack. We design such an algorithm and evaluate our algorithm through analysis
and simulation. Our evaluation quantifies the effect of our algorithm on system
performance as well as the security and the performance of our algorithm.
EXISTING SYSTEM:
Many protocols
in modern wireless networks treat a link’s channel condition information as a
protocol input parameter; we call such protocols channel-aware. Examples
include cooperative relaying network architectures, efficient ad hoc network
routing metrics, and opportunistic schedulers. While work on channel-aware
protocols has mainly focused on how channel condition information can be used
to more efficiently utilize wireless resources, security aspects of
channel-aware protocols have only recently been studied. These works on
security of channel-awareprotocols revealed new threats in specific network
environments by simulation or measurement. However, under-standing the effect
of possible attacks across varied network environments is still an open area
for study.
DISADVANTAGES
OF EXISTING SYSTEM:
·
Difficult
to guarantee QoS in MANETs due to their unique features including user
mobility, channel variance errors, and limited bandwidth.
·
Although
these protocols can increase the QoS of the MANETs to a certain extent, they
suffer from invalid reservation and race condition problems.
PROPOSED SYSTEM:
The false
channel condition reporting attack that we introduce in this paper is difficult
to identify by existing mechanisms, since our attack is mostly protocol
compliant; only the channel-condition measurement mechanism need to be
modified. Our attack can thus be performed using modified user equipment
legitimately registered to a network.
ADVANTAGES
OF PROPOSED SYSTEM:
·
The
source node schedules the packet streams to neighbors based on their queuing
condition, channel condition, and mobility, aiming to reduce transmission time
and increase network capacity.
·
Taking
full advantage of the two features, QOD transforms the packet routing problem
into a dynamic resource scheduling problem.
