When an earthquake hits, the dissemination of tsunami warnings can be crucial in saving lives. Unfortunately, some dissemination channels may be insufficient as they may be affected by the earthquake itself (damaged, loss of power or overloaded), may be expensive to build and are not available at certain places. In this research we propose a tsunami warning dissemination system that can serve as an additional channel to the existing systems. The system is lightweight, affordable, and can be powered autonomously. It disseminates messages to the commonly used GSM handsets and may reach numerous at-risk civilians. This paper also reports on the suggested integration plan of our proposed system within the current disaster management operation procedure in Indonesia. A set of experiments were carried out and they showed that the system has adequately met the users' requirements. It also shows the feasibility of the system to be integrated within the existing operational system and its associated early warning dissemination channels.

The statistical properties of traffic in Internet access networks have long been of interest to networking researchers and practitioners. In this paper, we analyse network traffic originating and terminating from various types of Internet access networks (Ethernet, Digital Subscriber Line, Wireless hotspot and their next tier Internet Service Provider's core network) and show that renewal processes having heavy-tail distributed interarrival times (also known as fractal renewal processes) have a great potential in capturing statistical properties of traffic in access networks.

This research addresses blackhole routing attacks —a fundamental security attack on the routing of data in IoT networks. Most IoT devices today, from medical devices to connected vehicles and even smart buildings, come bundled with the capability of communicating wirelessly with one another. Consumers are progressively embracing the concept of connected devices while recent studies indicate that security is not high on the priority list of manufacturers especially in the way these devices route and communicate data amongst themselves thus, leaving the door wide open to attacks and compromises. We propose a trust-based RPL routing protocol, which addresses the blackhole attacks. We show that our proposed system is both secure from blackhole attacks while not imposing undue overheads on network traffic.

The idea of employing scavenged power from human daily routines to run electronic devices are attracting increased attention of many researchers worldwide. However, there is still limited knowledge of energy characteristics generated by human motions. Moreover, level of human activities vary during a day from sitting for several hours to running on a treadmill. This highlights a vital need for energy management strategies. Hence, in this paper, we analyse more than 200 hours of day-scale human activities collected from 5 participants in 25 days. We divide energy generated by human daily routines into mild and intense activities. Subsequently, we develop an energy management policy which estimates required time for a device to store needed power between each active interval. We also evaluate the validity of our model using real world data. The results present an understanding towards a design of energy harvesting fitness gadgets.

A large-scale roll-out of a communication and measurement infrastructure is an essential prerequisite for more efficient and robust power grids with a high number of renewable energy resources. In this work, we propose an integrated optimization model for the minimum cost design of a wide area measurement system in smart power grids. The planning approaches proposed so far in the literature mostly consider the optimal placement of measurement devices and the design of a communication network independently, and assume the existence of only one communication technology. In contrast, our proposed novel model enables an integrated planning with a minimum number of both data concentrator and measurement units for observability of the whole power system, and a hierarchical heterogeneous communication network design under data communication requirements of delay and capacity. The application of the proposed model on test networks validates the reduction of the deployment and operational costs as a result of the integrated modeling.

Swarming and emergent behaviour techniques can offer simple control schemes for the organisation of many nodes, with little communications overhead and processing time. These mechanisms are robust against node losses, and are able to run on cheap, disposable platforms. For these reasons, we argue that these techniques are well suited to the tactical environment. This paper examines the usefulness of swarming techniques to address data ferrying in fragmented networks to provide delay-tolerant type communications. Simulation results from static, regular and irregular network topologies, and a dynamic topology representing a fictitious amphibious landing scenario show encouraging results in coordinating data ferries in a disconnected environment.

Network policy description languages (PDLs) enable the unambiguous specification of network behaviour. Due to the increasing number of PDLs and new and emerging network paradigms (eg: software defined networking) there is a need for tools to analyze these languages in an effective, efficient, and consistent manner. In this paper we present a taxonomy for policy description languages to help compare, understand, and create PDLs. This taxonomy is based on the policy-based network management (PBNM) literature and on consultations with industry experts, and has been validated by applying it to three PDLs (Ponder, Ponder2 and Kinetic). From this application we determine that all three PDLs promote reusability, maintainability and scalability, and that Ponder2 is easier to use in practice.

Network operators need to assess the effects of routing policies and traffic engineering methods in order to guide planning and operational decisions related to peering. We propose a peering analysis framework based on the correlation of inferred AS paths and traffic flow information. We define the data sets needed and a four-step methodology designed to reduce network data dimensionality, determine traffic proximity, identify traffic propensity, and quantify the impact of traffic locality. We demonstrate how the correlation of traffic flow and AS paths, and the application of our four-step approach, uncovers rich information when applied to a real-world case study of a local Internet service provider.

Wireless Body Area networks (WBANs) are a subset of wireless sensor networks that interconnect miniaturized nodes with sensor or actuator capabilities in, on, or around a human body. WBANs can operate over a number of different frequency bands such as MICS (Medical Implant Communications system), 2.4 GHz ISM (Industrial Scientific and Medical), UWB (Ultra-Wideband), and HBC (Human Body Communications) bands. Use for dual bands can improve connectivity, throughput and reliability. In this paper we proposed a metric called Weighed Multichannel Hop Count (WMHC) to provide better channel diversity and reduced in interference for inclusion in a multi-channel extension to the Ad Hoc on Demand Distance Vector (AODV) routing protocol for use in WBANs. We used the Castalia simulator to evaluate the metric. We showed that WMHC is a simple method of reducing interference and improving throughput.

Improvements to sensor devices including micro-electro mechanical devices that are used for information collection and dissemination has led to the introduction of Wireless Sensor Networks (WSN). Sensor nodes in a WSN are deployed over an area to collect data from the surroundings and to perform additional actions including data aggregation and storage, computations and data transmission to gateway devices. Clustering is a technique used to organize and structure the sensor network to split it into sub-networks, each with a controller node called the Cluster Head (CH). This technique reduces sensor node energy consumption and prolongs the network lifetime. The CH aggregates the data from the respective cluster members and transmits the aggregated data to the next level in the network. In this paper, a clustering algorithm named Energy Aware Neighbor Oriented Clustering (EANOC) is proposed to improve the network lifetime. EANOC is underpinned by earlier work into a Hybrid Weight Based Clustering Algorithm (HWCA) and focuses on a new neighborhood discovery type. The selection of the propagation model, transmission range, and the receiver signal strength indication value have a significant impact on the rate of energy utilization. Simulation results show that EANOC outperforms HWCA and the Dynamic Load-Balancing Cluster-Based Protocol in attaining longer network lifetime.
