In this paper, we present an asymmetric topology control (ATC) algorithm for wireless sensor networks. In this algorithm, the sensor nodes incrementally adjust their transmission. The algorithm had three phases of Neighbor Discovery, Construct Topology, and Data Transmission. In the phase of Neighbor Discovery, the nodes exchanged their positions and maximum transmission powers. In phase II, each sensor node collaboratively adjusted its transmission range (power) while keeping the network connectivity the same as that of the case of transmitting with the maximum power. In phase III, all the nodes transmit data with the adjusted transmission power. To assess the efficiency of the proposed algorithm, its performance is compared to those of previously published works. Our algorithm not only preserve power and average node degree and average link length, it has privileges which enable it to work properly even in the absence of conventional error handling mechanisms.

This paper illustrates the strategy followed for the management of broadband wireless communications in a hybrid network (mobile/radio). This management allows the optimization of both bandwidth and transmission rate of the applications deployed in the ground control stations (terrestrial applications) and onboard systems (train applications). It also describes the general aspects of a ‘train-to-earth’ communications architecture, which allows an easy and standard integration of applications both new and legacy.

Wireless communications using microwaves are increasingly important, e.g. Wi-Fi. Performance is a fundamental issue, resulting in more reliable and efficient communications. Laboratory measurements are made about several performance aspects of Wi-Fi (IEEE 802.11b, g) WEP point-to-point links using available access points from Enterasys Networks (RBTR2). Through OSI levels 4 and 7, detailed results are presented and discussed from TCP, UDP and FTP experiments, namely: TCP throughput, jitter, percentage datagram loss and FTP transfer rate. Conclusions are drawn about link performance.

DTN is able to adapt any mobility environment where any mobile routers and terminals are combined owing to the DTN's flexible hop-by-hop routing schemes. The existing DTN protocols like Epidemic, Prophet and Spray-and-Wait protocols rely on the message distribution mechanism where each DTN node produces one or more message copies. They can naturally adapt to the mobile situation where the destination node moves from an old connection endpoint to a new connection endpoint because any message copy may luckily be able to reach the new connection endpoint where the mobile node is newly connected. These protocols suffer from long latencies because message copies are not immediately forwarded until any suitable condition for forwarding is met. To solve these problems, we propose a Handoff-based Deterministic Routing Protocol (HDRP) that makes the best use of general handoff mechanisms intended for the IP network. This handoff mechanism includes the registration of locations by mobile nodes and backward propagation and caching of these locations over the experienced route. Our simulation results indicate that HDRP outperforms other existing protocols especially in terms of end-to-end latency.

In wireless sensor networks (WSN's), data aggregation is used to increase energy efficiency by means of eliminating redundancy and forwarding the collected abstract data of sensor nodes toward the sink. One of the most important challenges in WSN is to keep the remaining energy of nodes high and balanced to achieve longer system lifetime. In this article we propose an energy efficient data aggregation protocol named FFDA (Feed Forward Data Aggregation) for constructing the spanning tree, we also represent a new parameter called EAT (Energy After Transmission). This protocol considers EAT as the main parameter to select a node as root for spanning tree in the beginning of each round of data aggregation. Using this new parameter the remaining energy of nodes remain more balanced thus the first node die is delayed significantly and it also improves the system's lifetime as indicated by simulation results.

As an all-IP broadband wireless technology, WiMAX uniquely integrates well with existing enterprise network infrastructure, which allows an enterprise to either directly host a WiMAX network or, alternatively, use a public WiMAX network hosted by a network service provider for its enterprise services. In this paper, we will discuss these two different network hosting models for the enterprise. In particular, we will discuss 1) what the WiMAX network architecture should look like; 2) how can the security models of WiMAX be made stronger to serve the needs of enterprise users; 3) how WiMAX and WiFi can work together seamlessly to give the user a unified experience. The content in this paper is based on our recent research in this area.

Existing work has shown that rainfall has an effect on link quality. Some authors report a positive effect in moist conditions, whereas others demonstrate a significant decrease in link throughput as a result of rainfall or fog. The precise cause of these variations has not yet been conclusively established. This paper reports on long term (26 day) link quality results from 12 nodes deployed in a forest. We found that rainfall has the effect of decreasing the performance of 28% of good links (classified as those having above 90% packet reception), but simultaneously increasing the performance of 34% of poor links (those having below 50% packet reception). In addition, it was found that variations in link quality persisted for a few days after rainfall. This suggests that link variations are not a result of rain induced fading, but rather due to water sitting on node packaging. We present experimental evidence which demonstrates that changes in link quality (both positive and negative) are indeed due to the presence of water, capacitively loading the antenna, altering its radiation pattern.

Mobile ad hoc networks rely on node cooperation to perform and support basic functions like packet forwarding, routing and network management. In general, nodes' misbehaviour can significantly degrade the performance of the network. Cooperation enforcement schemes are seen as a lightweight alternative to conventional security techniques, providing a “softer” security layer to protect basic networking operations. The aim of this paper is to survey representative cooperation enforcement schemes exploiting a reputation system proposed in related research literature. Their distinct features are analyzed and their relative merits and weaknesses are discussed.
