New demand for energy efficiency, scalability, support for varying traffic load, flexibility in provided features and adoption to novel network architectures forces the “Plain Old Base Station” to change.

In this context particular emphasis is put on energy savings. Simulation results for macro base stations with different modularization levels and operation schemes give image of the relation between base station design and its energy consumption and promises excellent energy savings by a factor of 2 compared to conventional base stations.

To solve this issue, we introduce a technique to determine network layer queue size limit of ingress radio interfaces in the multi-radio MAPs. The intention is to partially control the transmit probability of forwarded packets during network congestion. End-to-end throughput and delay with four types of queue configurations were measured in an experimental testbed. The results show that a delay variance reduction of 38× between the first hop and the subsequent hops can be achieved using the proposed technique with a minimal drop (<0.05Mbps) in average throughput.

To our best knowledge, studies on the performance of the IEEE 802.11n technology in foliage area have not been fully explored. We have conducted line-of-sight and non-line-of-sight measurements through the tropical foliage using directional high gain antennas to determine the throughput and other well-known performance metrics. It is observed that by utilizing the key features of 802.11n such as channel bonding and short guard interval, superior performance results can be achieved for both aforementioned situations. Precise correlation of utilized hardware specification and acquired results in different points is another aspect of this work. The findings are useful for future rural wireless deployment particularly with low height antenna using IEEE 802.11n technology.

To address these challenges, new detection systems which do not rely on knowledge of internal device state are investigated here. This paper shows that this lack of state information requires an additional metric (The exchange timeout window) for detection of WLAN Denial of Service Probe Flood attacks. Variability in this metric has a significant influence on the ability of a detection system to reliably detect the presence of attacks. A parameter selection method is proposed which is shown to provide reliability and repeatability in attack detection in WLANs. Results obtained from ongoing live trials are presented that demonstrate the importance of accurately estimating probe request and probe response timeouts in future Independent Intrusion Detection Systems.

The problem is one of packing a set of blocks of arbitrary sizes on an area, with the objective of minimizing the area's usage along the y-axis, under the condition that the x-position of the blocks are fixed (as given in the input). The problem has uses in memory management, berth allocation, and can potentially be used in the allocation of bandwidth resources in a network. Li et al. [4] considered the case of the problem where the width of the blocks (their dimension along the y-axis) is to be no larger than a given number. They obtained several approximation algorithms for special cases of the problem, by first studying the feasibility of several subcases with further restriction, such as limiting the y-dimension of the area to pack the blocks. We believe that such feasibility results on subcases of the problem can help in obtaining algorithms for other special cases of the problem. In this paper we propose a method to automatically derive such results. Our implementation of a simplified version of the proposed method in C++ correctly duplicated many of the earlier results obtained by Li et al.

Being able to obtain real-time information will further enhance these benefits. Current systems rely on huge infrastructure investments by governments to install cameras, road sensors and billboards to keep motorists informed. These efforts can only be, at best, available at pre-identified hotspots. Radio broadcast is an alternative, where they rely on reports by other motorists. However, such reports are often delayed and not tailored to individual motorist. Seeing the limitations of existing approaches to obtain real-time road conditions, this research work leverages on mobile devices that provide context sensitive information to propose a predictive analytics framework based on a Bayesian Network for road condition prediction. This paper aims to contribute to (i) defining a set of evidences (variables) that could potentially be utilized for road condition prediction and (ii) construction of a Bayesian Network model to predict road conditions. In conclusion, we presented a novel approach to provide potentially unlimited coverage of road traffic conditions with substantially reduced infrastructure investments.
