“…Kumar, Prabhu, Dunham, and Seydim (2002), proposed TCOT where the master employs timeouts towards deciding about the outcome of a particular transaction. Younas, Chao, Wang, and Huang (2007) dealt with mobile host disconnections in transactions that involve several mobile and fixed hosts by a protocol that discovers alternative mobile hosts that may replace the disconnected ones. Nouali, Doucet, and Drias (2005) proposed a protocol for transactions that span across several mobile hosts, which may move across different interconnected network cells.…”

In this paper, the authors investigate the concept of designing user-centric transaction protocols toward achieving dependable coordination in AmI environments. As a proof-of-concept, this paper presents a protocol that takes into account the schedules of roaming users, which move from one AmI environment to another, avoiding abnormal termination of transactions when users leave an environment for a short time and return later. The authors compare the proposed schedule-aware protocol against a schedule-agnostic one. Findings show that the use of user-centric information in such situations is quite beneficial.

“…Until now, some interesting approaches have been proposed for dealing with transactions in the context of the aforementioned execution models. In [6], for instance, the authors deal with mobile host disconnections in transactions that involve several mobile and fixed hosts by a protocol that discovers alternative mobile hosts that may replace the disconnected ones. In [7] the authors propose a protocol for transactions that span across several mobile hosts, which may move across different interconnected network cells.…”

Abstract. In this paper we investigate the concept of designing user-centric transaction protocols towards achieving dependable coordination in AmI environments. As a proof-of-concept, we propose a protocol that takes into account the schedules of roaming users that move from one AmI environment to another, to avoid abnormal terminations of transactions when the users leave an environment for short, only to return later. We compare the proposed schedule-aware protocol against a schedule-agnostic one. Our findings show that the use of user-centric information in such situations is quite beneficial.

“…In the ninth paper [9], Younas et al present a new transaction management approach for mobile service provisioning which is based on advanced transaction models and fuzzy selection criteria. The proposed technique employs a novel QoS consensus moderation approach in order to select preferred mobile services among various alternatives, thus providing multiple pathways to the completion of mobile service transactions.…”

The recent technological development in wireless communication and mobile networks has led to many challenging problems that require new performance evaluation tools and methods to keep up with their rapid evolution and increasing complexity. As a result, performance modelling and evaluation has gained increasing importance. Whilst new applications and enhanced technologies are facilitating users' demands, researchers are facing challenges to provide models, tools and analytical techniques to aid with system design, prototyping, testing and performance evaluation.This special issue presents 10 high-quality papers from the first international workshop on Performance Analysis and Enhancement of Wireless Networks (PAEWN 2006) held in conjunction with the IEEE 20th International Conference on Advanced Information Networking and Applications (AINA 2006), Vienna, Austria and some related tracks. These papers were selected by the scientific program committee and extended and revised before undergoing further rigorous peer-review. The purpose of this workshop was to provide an international forum for researchers and industry practitioners to present their state-of-the-art research on performance analysis and evaluation studies in all aspects of wireless networking, and to exchange ideas and explore new avenues of collaborations. This workshop attracted a large number of quality submissions and the presentations generated very interesting discussions.This special issue has drawn upon the wide scope of challenging and timely issues related to wireless networks and the contents are built on experimental studies, analytical modelling, simulation studies, traffic modelling and applications for challenging issues.In the first paper [1], Speer and Chen discuss an important issue of energy conservation in datadriven wireless sensor networks (WSNs), where the system performs data sensing and retrieval as a response to users' queries at runtime. They argue that although the use of redundancy is desirable in terms of satisfying user queries to cope with sensor and transmission faults, it may adversely shorten the lifetime of the WSN. The authors analyse the effect of redundancy on the mean time to failure (MTTF) of a WSN in terms of the number of queries the system is able to answer correctly before it fails due to either sensor/transmission faults or energy depletion. In particular, they investigate the effect of redundancy on the MTTF of cluster-structured WSNs for energy conservations. Using a probability model, this paper demonstrates the existence of a tradeoff between redundancy and MTTF. Moreover, there exists an optimal level of redundancy that should be used by the system to maximize the MTTF.
