  • When the concept of a network without wires was first suggested more than two decades ago, it sparked the imagination of scientists, product vendors, and users around the globe eager for the convenience and flexibility of a free roaming connection. Unfortunately, as the variety of wireless solutions began to emerge, anticipation turned to disappointment.The first wave of solutions proved inadequate for the networking, portability, and security needs of a changing IT environment.

  • Insider attacks pose an often neglected threat scenario when devising security mechanisms for emerging wireless technologies. For example, traffic safety applications in vehicular networks aim to prevent fatal collisions and preemptively warn drivers of hazards along their path, thus preserving numerous lives. Unmitigated attacks upon these networks stand to severely jeopardize their adoption and limit the scope of their deployment.

  • Due to faster deployment and lower cost of wireless local loop (WLL) infrastructure as compared to a wired one, worldwide roll-out of WLL service has been highly anticipated. Most of WLL systems deployed so far belong to narrowband systems mainly aimed at providing voice service. These systems can be used as a bypass of wire-line local loop in dense areas and as an extension of existing telephone network in remote areas. In recent years, media-rich content of Internet has put speed pressure on the local loop.

  • Wireless local loop (WLL) or fixed wireless access systems are attractive solutions to the so-called last mile problem because of their low capital cost, fast network deployment capability and low maintenance cost [1]. They would, therefore, be effective during the transition period from fibre to the curb (FTTC) to fibre to the home (FTTH). WLL has the potential of becoming a major competitor of local exchange networks, cable television (CATV) networks

  • A wireless ad-hoc network is a wireless network deployed without any infrastructure. In such a network, there is no access point or wireless router to forward messages among the computing devices. Instead, these devices depend on the ad-hoc mode of their wireless network interface cards to communicate with each other. If the nodes are within the transmission range of the wireless signal, they can send messages to each other directly. Otherwise, the nodes in between will forward the messages for them. Thus, each node is both an end system and a router simultaneously....

  • Wireless Local Loop (WLL) systems offer quick deployment, high data rates and dynamic capacity. These should be compelling reasons for WLL System to supplant wired systems. WLL systems are having only limited success in displacing wired systems because wired systems provide proven reliability at lower cost. Will this always be true? This chapter addresses that one technology path designers can follow to reduce WLL system cost, especially for the more numerous low data rate and voice user.

  • Wireless Local Loop (WLL) is projected to experience phenomenal growth over the next years. The nature of WLL is such that terminals are not mobile and once installed the subscriber expects trouble-free operation without any service requirements. Meanwhile, new functionality involving enhanced codecs and modems are being developed and expected to be made available to the subscriber. A major challenge facing WLL operators consists of upgrading WLL terminals that are already deployed at the customer site with new functionality [1,3].

  • As of November 8, 2010, Manually entered IP addresses are no longer supported on campus if the device is capable of using DHCP. This is true for normal dynamically assigned IP's and Static IP's. All NEW devices added to the network must be set to receive their network address via DHCP (Dynamic Host Configuration Protocol). This is the default setting for campus PC and Mac workstations and most printers. No user action is anticipated. There is no change or downtime expected for the vast majority of campus workstations or devices. We have made great efforts to put exceptions in place...

  • Hello, in this module we are going to discuss wireless networking. Specifically, we'll take a look at how wireless technology works, how it is commonly deployed, and the security issues associated with using it. Because wireless communications can penetrate opaque objects such as buildings, the risk of someone accessing a private network increases markedly. With wireless, an attacker does not need to gain access to physical cables or jacks, but only needs to have an antenna and be within range of the transmissions....
