— This paper presents the ALCA (Asymmetric Link Collision Avoidance) protocol. ALCA was designed to deal with a known deficiency of the Basic Scheme [1] for power control in 802...
A dynamically extensible control plane is a key enabling feature of next generation intelligent selfconfiguring networks. This extensibility can be achieved by enabling service de...
Ad-hoc wireless networks with multi-rate radios (such as 802.11a, b, g) require a new class of MAC/PHY aware metrics that take into account factors such as physical-layer link spe...
Abstract—This paper examines the following wireless data access scenario: a number of clients are interested in a set of data items kept at the server. A client sends a query req...
Constructing indoor radio maps plays an important role in many services and applications such as wireless base station planning. In this paper, we propose a hybrid approach to con...

This paper considers the small-world phenomenon in two contexts: ubiquitous computing and security. We argue that small-world properties emerge in ubicomp systems due to their nat...
— Message ferrying (MF) [2], a viable solution for routing in highly partitioned ad-hoc networks, exploits message ferries to transfer packets between disconnected nodes. This pa...
IEEE 802.11 Medium Access Control (MAC) called Distributed Coordination Function (DCF) provides two different access modes, namely, 2-way (basic access) and 4-way (RTS/CTS) hands...
The IEEE 802.11e extensions for QoS support in WLAN define the transmission opportunity (TXOP) concept, in order to limit the channel holding times of the contending stations in ...
To be able to utilize the generative potential of future networks for service composition, the attributes of services and networks must be appropriately formalized, stored and mad...
