Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers. Node placement problems have been investigated for a long time in the optimization field due to numerous applications in location science. In our previous work, we evaluated WMN-GA system which is based on Genetic Algorithms (GAs) to find an optimal location assignment for mesh routers. In this paper, we evaluate the performance of Weibull distribution of mesh clients for two WMN architectures considering throughput, delay, jitter and energy metrics. For simulations, we used ns-3, Optimized Link State Routing (OLSR) and Hybrid Wireless Mesh Protocols (HWMP). We evaluate the performance for Weibull distribution of mesh clients by sending multiple Constant Bit Rate (CBR) flows in the network. The simulation results show that for HWMP, the throughput of Hybrid WMN is higher than I/B architecture. However, for OLSR the throughput is almost the same for both WMN architectures. For HWMP, the delay of I/B WMN is a lower compared with Hybrid WMN. But for OLSR, the delay of Hybrid WMN is a little bit lower than I/B WMN. For both protocols, the jitter of Hybrid WMN is a little bit lower than I/B WMN. For both protocols, the energy decrease almost the same for both WMN architectures. © 2015 IEEE.

With the accelerating development of aged tendency of population and rapid growth in the number of the disabled caused by diseases or injuries, the wheelchair with good performance for the aged and disabled is attracting the attention from the society. A wheelchair can 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 to go through narrow doorways. The wheelchair must be wide enough to prevent the patient from falling on the floor. A large footprint is therefore desirable for stability and safety, while wheelchairs must conform to dimensional constraints. In this paper, we present the implementation and evaluation of an Omni directional wheelchair, which has a small size and can move easily in narrow spaces. In order to evaluate the implemented wheelchair, we carried out some experiments and discussed some implementation and application issues. The experimental results show that the implemented wheelchair in general works properly, but its still needs improvements. © 2015 IEEE.

Ad-Hoc Networks, Mobile Ad-Hoc Networks (MANETs), Wireless Mesh Networks (WMNs) are attracting a lot of attention from wireless network researchers, because of their potential use in several fields such as collaborative computing and communications. Considering mobility of the terminals, routing is a key process for operation of WMNs. In this paper, we present the implementation of a simulation system for these networks. We analyze the performance of AODV, OLSR and HWMP protocols considering static and mobile node scenarios. For evaluation we considered throughput, delay and remaining energy metrics. The simulation results show that for both scenarios, the AODV protocol performs better than other protocols. The delay of AODV in static scenario is lower than other protocols. However, the delay of HWMP is better than other protocols in mobile scenario. For all routing protocols, the remaining energy of mobile scenario is higher than static scenario. © 2015 IEEE.

In this paper, we propose and evaluate a new fuzzy-based reliability system for Peer-to-Peer (P2P) Communications in JXTA-Overlay platform considering as a new parameter the sustained communication time. In our system, we considered four input parameters: Data Download Speed (DDS), Local Score (LS), Number of Interactions (NI) and Sustained Communication Time (SCT) to decide the Peer Reliability (PR). We evaluate the proposed system by computer simulations. The simulation results have shown that the proposed system has a good performance and can choose reliable peers to connect in JXTA-Overlay platform. © 2016 IEEE.

Recently, there are many problems caused by global environment warming. The limited natural resources require efficient methods and systems for recycling and processing of the wastes for a better environment. One of the problems today is the processing of the kitchen garbage, because when they become in large amounts in small areas, the natural capacity of the environment cannot assimilate them. Therefore, construction of the recycling systems is needed to save the resources and minimize the wastes. For this reason, in this paper, the authors have proposed and implemented a waste management robot system, which can change the kitchen garbage to compost. Then, the compost can be mixed with the ground and used for growing of vegetables and other plants. The proposed system uses the information network, sensor technology and robot technology. The authors present in this paper, the implementation of the proposed system and evaluate its performance by experimental results. Copyright © 2015, IGI Global.

In recent years, more and more convenient facilities and equipments have been developed in order to satisfy the requirements of elderly people and disabled people. Among them, wheelchair is a common one which is widely used and can 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 to go through narrow doorways. The wheelchair must be wide enough to prevent the patient from falling on the floor. A large footprint is therefore desirable for stability and safety, while wheelchairs must conform to dimensional constraints. In this paper, we present the implementation and evaluation of an omnidirectional wheelchair, which has a small size and can move easily in narrow spaces. In order to evaluate the implemented wheelchair, we carried out some experiments and discussed some implementation and application issues.

Due to the opportunities provided by the Internet, people are taking advantage of e-learning courses and during the last few years enormous research efforts have been dedicated to the development of e-learning systems. So far, many e-learning systems are proposed and used practically. However, in these systems the e-learning completion rate is low. One of the reasons is the low study desire and motivation. In this work, we designed an IoT-Based E-Learning testbed to improve the system performance. The proposed system is able to stimulate the learner's motivation by using implemented SmartBox, microwave sensor module and decision tree. © 2016 IEEE.
