This work presents an approach for enhancing the K-means algorithm in the classification phase. The approach consists in a heuristic, which at each time that an object remains in the same group, between the current and the previous iteration, it is identified as stable and it is removed from computations in the classification phase in the current and subsequent iterations. This approach helps to reduce the execution time of the standard version. It can be useful in big data applications. For evaluating computational results, both the standard and the proposal were implemented and executed using three synthetic and seven well-known real instances. After testing both versions, it was possible to validate that the proposed approach spends less time than the standard one. The best result was obtained for the transactions instance when it was grouped into 200 clusters, achieving a time reduction of 90.1% with a reduction in quality of 3.97%.

The IPv6 routing protocol for low power and lossy networks (RPL) was proposed as a routing standard for wireless sensor networks (WSNs). However, the RPL performance drastically degrade in the case of nodes' mobility. Therefore, we propose in this paper multipath routing schemes to adapt RPL to mobility scenarios. The first mobility-based braided multipath RPL (MBM-RPL) scheme establishes an alternative path braided with the primary one to replace the loose link (the up to fail link) along the first network route. The second proactive multipath mobility-based RPL (PMM-RPL) approach establishes all node disjoint routes between each node in the network and the sink. Data would not be duplicated on secondary paths until a primary path vulnerability detection. Both MBM-RPL and PMM-RPL performance are evaluated in terms of packet loss rate (PLR), average transmission delay (ADT) and the generated network overhead using the Cooja/Contiki simulation environment.
提出了面向低功耗损耗网络(RPL)的IPv6路由协议作为无线传感器网络(WSNs)的路由标准。然而，在节点移动的情况下，RPL性能会急剧下降。因此，我们在本文中提出了多路径路由方案，以使RPL适应移动场景。MBM-RPL (first mobility-based braided multi - path RPL)是一种基于第一移动性的编织多路径RPL (MBM-RPL)方案，它建立了一条与主路径编织的替代路径，以取代第一条网络路由上的松散链路(up to fail链路)。第二种基于主动多路径移动的RPL (PMM-RPL)方法在网络中每个节点和sink之间建立所有节点不相交的路由。在检测到主路径漏洞之前，不会在辅助路径上复制数据。使用Cooja/Contiki仿真环境，根据丢包率(PLR)、平均传输延迟(ADT)和生成的网络开销来评估MBM-RPL和PMM-RPL的性能。

Volunteer cloud is a new concept of cloud computing where volunteers, i.e., user machines are used instead of or in addition to dedicated resources. Although volunteer clouds offer potential benefits in terms of energy and cost saving as well as elasticity, the volatility and the scalability of the volunteer resources are still open challenges that need to be investigated. In this paper, we focus on managing the connectivity in a scalable and dynamic fashion in volunteer clouds. We show that volunteer clouds could be modelled by a hierarchical small-world structure, characterised by short average path lengths among nodes, and strong local clustering, which implies small latency between nodes and therefore robust forwarding. Furthermore, we explore the benefits of the use of the recursive internetwork architecture (RINA) as a networking solution. Finally, simulation results show that our proposal achieves a trade-off between bounding the routing table size and ensuring transmission efficiency.

The aged tendency of population and rapid growth in the number of disabled people caused by diseases or injuries require to build wheelchairs with good performance. Also, the wheelchair should provide the user with many benefits, such as maintaining mobility, continuing or broadening community and social activities, conserving strength and energy, and enhancing quality of life. The wheelchair body must be compact enough and should be able to make different movements in order to have many applications. In this paper, we present the implementation and experimental evaluation of an omnidirectional wheelchair for sports and moving in rooms with narrow spaces. The experimental evaluation shows that the implemented wheelchair has a good behaviour and can be used for real applications.

Ambient intelligence (AmI) deals with a new world of ubiquitous computing devices, where physical environments interact intelligently and unobtrusively with people. AmI environments can be diverse, such as homes, offices, meeting rooms, schools, hospitals, control centers, vehicles, tourist attractions, stores, sports facilities, and music devices. In this paper, we present the design and implementation of a testbed for AmI using Raspberry Pi mounted on Raspbian OS. We analyse the optimised link state routing (OLSR) and wired equivalent privacy (WEP) protocol in an indoor scenario, and mean shift clustering algorithm considering sensing data. For evaluation we considered throughput, delay and jitter metrics, and respiratory rate and heart rate metrics. The experimental and simulation results show that the nodes in the testbed were communicating smoothly and the mean shift clustering algorithm have a good performance.

In order to realise eco-society, we have to reduce the electric energy consumed by servers in a cluster in addition to satisfying performance requirements. Virtual machines are now widely used to support applications with virtual computation service in clusters of servers. Here, a virtual machine on a host server can migrate to a guest server while processes are being performed on the virtual machine. In this paper, we propose an energy-aware migration of virtual machines (EAMV) algorithm where not only a virtual machine is selected to perform a process issued by a client but also a virtual machine migrates to a guest server which is expected to consume smaller electric energy to perform processes on the virtual machine. In the evaluation, we show the total electric energy consumption of servers and the average execution time of processes can be reduced in the EAMV algorithm compared with non-migration algorithms.

The rapid growth of employing devices as tools in daily life and the technological revolution have led to the invention of a novel paradigm; the Internet of Things (IoT). It includes a group of ubiquitous devices that communicate and share data with each other. These devices use the Internet Protocol (IP) to manage network nodes through mobile ad hoc networks (MANET). IoT is beneficial to MANET as the nodes are self-organising and the information reach can be expanded according to the network range. Due to the nature of MANET, such as dynamic topology, a number of challenges are inherent, such as Denial of Service (DoS) attacks. DoS attacks prohibit legitimate users from accessing their authorised services. In addition, because of the high mobility of MANET, the network can merge with other networks. In this situation, two or more networks of untrusted nodes may join one another leaving each of the networks open to attack. This paper proposes a novel method to detect DoS attacks immediately prior to the merger of two MANETs. To demonstrate the applicability of the proposed approach, a Grayhole attack is used in this study to evaluate the performance of the proposed method in detecting attacks.

Vehicular ad hoc network provides safety applications for next generation intelligent transport systems. By periodically transmitting mobility information in basic safety messages (BSMs), vehicles get an overview of the neighbourhood. As applications involving vehicular networks impact human safety, reliability of BSMs is a key requirement, which however is a challenging task in heavy traffic scenarios where many BSMs are queued up simultaneously for signature verification. This results in long verification delays for many critical BSMs from nearby vehicles. To overcome this challenge, we propose two adaptive security mechanisms in this paper that can be used by the ITS applications to enhance their QoS and maintain good level of security. The first technique is a receiver-oriented technique that uses channel aware mechanism to prioritise the signature verification of BSMs from closer neighbours. The second technique is transmitter based that can adaptively select the best security level for BSMs according to cryptographic loss rate. Simulation results verify the performance enhancement achieved by the proposed framework in terms of several safety awareness metrics as compared with the existing schemes.

Mobile computing has many application domains. One important domain is that of mobile applications supporting collaborative work. In a collaborative work, the members of the team have to take decision or solve conflicts in project development and therefore members have to vote. In this work, we present a voting model, that we call qualified voting, in which every member has a voting score according to four parameters: number of activities that member participates (NAMP), number of activities that member successfully finished (NAMSF), number of online discussions that member participated (NODMP), number of activities the member fails (NAMF). Then, we use fuzzy approach to compute a voting score for the member. We present two fuzzy based voting systems (called FPVS1 and FPVS2). The simulation results show that when NAMP, NAMSF and NODMP are high, the voting score is high, but with increasing of the NAMF, the VS is decreased. Comparing the complexity of FPVS1 and FPVS2, the FPVS2 is more complex than FPVS1, but FPVS2 can select better peers for the collaborative work.

Wireless sensor and actor network (WSAN) is formed by the collaboration of micro-sensor and actor nodes. Whenever there is any special event, i.e., fire, earthquake, flood or enemy attack in the network, sensor nodes are responsible to sense it and send information towards an actor node. The actor node is responsible to take prompt decision and react accordingly. In this work, we propose and implement two fuzzy based actor selection systems (FBASS): FBASS1 and FBASS2 for actor selection in WSANs. The systems decide whether the actor will be selected for the required job or not based on data supplied by sensors and actual actor condition. We evaluated the proposed system by computer simulations. Comparing FBASS1 with FBASS2, the FBASS2 is more complex than FBASS1, because it has more rules in fuzzy rule base (FRB). By increasing node density, the FBASS2 can save better the energy.
