BOOST: A BOOtSTrapping Protocol for 802.11-Based Self-Organizing Hierarchical Wireless Ad-Hoc Networks
White Papers Also, in the case of ad-hoc networks that require no fixed network infrastructure, there is a need to allocate channels carefully so as to minimize interference and improve the system performance. The APs need to be placed optimally to provide...

A Shoelace-Based QoS Routing Protocol for Mobile Ad Hoc Networks Using Directional Antenna
White Papers Due to the directional antenna property, these cross links can simultaneously transmit data without any data interference. This paper proposes a new QoS routing protocol for Mobile Ad hoc NETwork (MANET) using directional antenna.

Interference-Aware Topology Control for Wireless Sensor Networks
White Papers This paper presents several algorithms to construct network topologies such that the maximum (or average) link (or nodal) interference of the topology is either minimized or approximately minimized. However, only a few topology control methods take...

A QoS Routing and Admission Control Scheme for 802.11 Ad Hoc Networks
White Papers Available bandwidth can only be determined by also considering interference at neighboring nodes. Also, due to self-interference of flows the required bandwidth of a flow varies for each link of a route.

MC-CDMA in Personal Area Networks - A Combined PHY and MAC Approach
White Papers Air interfaces for personal area networks need to be flexible and adaptive as well as robust against interference as no dedicated frequency band will be assigned to PAN services. PANs establish an ad-hoc network of personal devices around a person...

IRMA: Integrated Routing and MAC Scheduling in Multi-Hop Wireless Mesh Networks
White Papers In IRMA, a centralized algorithm is used to allocate resources to each flow based on traffic flow specifications and the network compatibility graph based on a generalized n-hop interference model. The IRMA approach is motivated by the fact that...

How to Outperform IEEE 802.11: Interference Aware (IA) MAC
White Papers This paper proposes Interference Aware (IA) MAC, a modified version of standard IEEE802.11. To make it feasible, the paper proposes to insert some information about interference and received power levels into IEEE 802.11 control packets.

Implementing Voice Over Wireless Networks: Realities and Challenges
White Papers Making matters worse, Radio Frequency (RF) interference, RF noise, and the physical environment dramatically affect wireless coverage and capacity. The cold reality is that ad-hoc design methods and site surveys are insufficient for wireless...

Troubleshooting the WLAN
News The problem could also be related to radio interference or a break in the physical link between the wireless access point and the wired network. This article assumes that you're troubleshooting an infrastructure network, and not an ad hoc network.

Sony goes wireless with Bluetooth kit
News Sony could only vouch for the lack of interference with its own 802.11b products -- a network access point/hub and a PC Card due in the UK in September. As far as interoperability with other Bluetooth equipment and interference with 802.11b...

Motorola fights on in ultrawideband battle
News But many questions remain: whose technology best matches the way people will want to use it, which one will best match whatever the regulators allow, and how bad the risk of interference to other services is.

Enhancements of the IEEE 802.11, a MAC Protocol for Ad Hoc Network With History of Power Adjustment
White Papers Through many simulations, it shows that the algorithm outperforms the IEEE 802.11 standard both in the static and dynamic network and also in high interference environments. This paper proposes a MAC protocol which improves disadvantages of the...
