Minimization of Call Blocking Probability using Mobile Node velocity
"... Abstract—Due to rapid growth in IEEE 802.11 based Wireless Local Area Networks (WLAN), handoff has become a burning issue. A mobile Node (MN) requires handoff when it travels out of the coverage area of its current access point (AP) and tries to associate with another AP. But handoff delays provide ..."

Use of Minimum Node Velocity Based Stable Connected Dominating Sets for Mobile Ad hoc Networks
"... We propose an algorithm to determine stable connected dominating sets (CDS), based on node velocities, for mobile ad hoc networks (MANETs). The proposed minimum velocity-based CDS (MinV-CDS) algorithm prefers slow-moving nodes with lower velocity, rather than the usual approach of preferring nodes w ..."

Opportunistic Media Access for Multirate Ad Hoc Networks
, 2002
"... The IEEE 802.11 wireless media access standard supports multiple data rates at the physical layer. Moreover, various auto rate adaptation mechanisms at the medium access layer have been proposed to utilize this multi-rate capability by automatically adapting the transmission rate to best match the c ..."

. Finally, we perform an extensive set of ns-2 simulations to study the impact of such factors as node velocity, channel conditions, and topology on the throughput of OAR.
Determining the Optimal Configuration for the Zone Routing Protocol
- IEEE JOURNAL ON SELECTED AREAS IN COMMUNICATIONS
, 1999
"... The zone routing protocol (ZRP) is a hybrid routing protocol that proactively maintains routes within a local region of the network (which we refer to as the routing zone). Knowledge of this routing zone topology is leveraged by the ZRP to improve the efficiency of a reactive route query/reply mech ..."

in network behavior and a mechanism to allow individual nodes to identify these changes given only limited knowledge of the network behavior. In the first half of this paper, we demonstrate the effects of relative node velocity, node density, network span, and user data activity on the performance of the ZRP
Throughput-Delay Trade-off in Wireless Networks

"... ...network model for studying the way throughput scales in a wireless network when the nodes are fixed, and showed that the throughput per source-destination pair is... Grossglauser and Tse (2001) showed that when nodes are mobile it is possible to have a constant or throughput scaling per source-de ..."

respectively. For the Grossglauser-Tse mobile network model, we show that the delay scales as, where,.# is the velocity of the mobile nodes. We then describe a scheme that achieves the optimal order of delay for any given throughput. The scheme varies (i) the number of hops, (ii) the transmission range

Radio interferometric tracking of mobile wireless nodes
- in MobiSys ’07: Proceedings of the 5th international
"... Location-awareness is an important requirement for many mobile wireless applications today. When GPS is not appli-cable because of the required precision and/or the resource constraints on the hardware platform, radio interferometric ranging may offer an alternative. In this paper, we present a tech ..."
