Wireless networking has been enjoying fast development, evidenced by wide deployments of many wireless networks of various sizes, such as wireless personal area networks (WPANs), local area networks (WLANs), metropolitan area networks (WMANs), and wide area networks (WWANs).
But he also expressed caution that with so many wireless networks under construction around the world, companies like Telus might find themselves in tough competition with new marketers who are able to buy capacity at inexpensive rates.
Captured nodes pose security threats to many wireless networks.
Hence, in heterogeneous environment, where there are many wireless networks operating in the same area, vertical handover will become commonplace.
A critical issue in many wireless networks is how to establish the best possible quality connections between users to base stations.
(i) It is well known that malicious nodes can enter many wireless networks due to imperfectness of access control or through node compromising attack.
But over the next couple of days I manage with great difficulty to sniff out and glom onto a couple of the many wireless networks that various vendors are running in the convention hall.
Orthogonal frequency division multiple access (OFDMA) has been adopted in many wireless networks such as IEEE 802.16 and the 3rd Generation Partnership Project long-term evolution (LTE), due to many beneficial characteristics.
Since in many wireless networks nodes can come and go in an arbitrary manner, there must be an inherent capability of inter-node communication between every pair of nodes.
