Issues and challenges in Wireless Network Security 2
Introduction
Wireless network is operating under infrastructure mode, such as 802.11, 802.16, and
Cellular networks. Ad-hoc network is operated without infrastructural support. Network has the
open nature of communication that is a security issue for network itself. There are two main
issues in the network are Authentication and privacy. Network is also having other issues like
denial of service (referred as DOS) attack (Mukherjee, Fakoorian, Huang, & Swindlehurst,
2014).
We have different wireless technologies for making communication better, such as Wi-Fi,
WI-MAX, Wireless USB, and many more. Wi-Fi is used for short-range mobile access network
and Wireless Local Area Networks (referred as LAN). For broadband connectivity of systems,
Wi-MAX technology is used. There are other technologies also for connection making, such as
infrared, Gigabit wireless. Infrastructure of a network is based on different criteria, such as fixed
infrastructure, Ad-hoc wireless networks, and mixed mode networks. In case of fixed
infrastructure, base station is used for; provide network to mobile nodes, such as sensor network
and cellular network. In case of ad-hoc network, there are no needs of infrastructural supports.
Mobility of nodes is allowed, such as laptops and mobile operating in ad-hoc mode (Tahir &
Loo, 2009). In case of mixed mode, any devices take both modes as per requirement. A proper
model is follow for designing a network such as lightweight and local control in a network.
Some difficulties of wireless network as compared to wired networks are transmission,
interference, resource constraints, mobility, and physical carrier sensing. In next parts of this
report, I will discuss about wireless networks models, different layers of TCP/IP suite and issues
and challenges with solutions (Liang & Yu, 2015).
Models of wireless networks
Unit disk graph model
In this model, u and v are nodes and R is radius of network. This is simple models for
connecting different nodes in a network.
If d(u,v) <= R than u and v are connected. They can have transmission rights in that network.
