The convergence of mobile edge computing (MEC) to the current Internet of Things (IoT) environment enables a great opportunity to enhance massive IoT data transmission. In the narrowband Internet of Things (NB-IoT), the huge number of IoT devices sends the information to the remote network. Simultaneously, the massive IoT devices from the heterogeneous locations access to the radio remote head (RRH) resources to communicate with the remote servers (e.g., mobile cloud computing), while there are limited resources in NB-IoT environments. Therefore, many IoT traffic may be discarded and may have too long queue times for each traffic where it can cause the battery life reduction of the IoT devices. To cope with the mentioned issues, this paper proposed a novel and efficient IoT data transmission scheme based on dynamic resource sharing of RRHs called efficient dynamic resource sharing scheme (E-DRSS). The proposed E-DRSS computes the heterogeneous IoT device with different resources into new groups, and then each group of IoT devices is selected for accessing its appropriate RRH. The evaluation of performance shows that the proposed scheme enhances quality of service (QoS) outperform on the current IoT scheme in terms of the jitters, end-to-end (E2E) latency, throughputs, and number of packets drop during transmission. Therefore, the proposed scheme is suitable to handle more IoT devices simultaneously and increase the communication reliability.

The traditional extended Kalman algorithm for multi-target tracking in the field of intelligent transportation does not consider the occlusion problem of the multi-target tracking process, and has the disadvantage of low multi-target tracking accuracy. A multi-target tracking algorithm using wireless sensors in an intelligent transportation system is proposed. Based on the dynamic clustering structure, the measurement results of each sensor are the superimposed results of sound signals and environmental noise from multiple targets. During the tracking process, each target corresponds to a particle filter. When the target spacing is relatively close to each other, each master node realizes distributed multi-target tracking through information exchange. At the same time, it is also necessary to consider the overlap between adjacent frames. Since the moving target speed is too fast, the target occlusion has the least influence on the tracking accuracy, and can accurately track multiple targets. The experimental results show that the proposed algorithm has a target tracking error of 0.5 m to 1 m, and the tracking result has high precision.

“…In spite of this weak point, we have adopted the IEEE 1588 as a PTP of EP-DFS, because the weak point can be overcome by compensating methods which are based on the SDN techniques. This synchronization procedure is very similar to the POSIA (Packet fOrwarding Scheme based on Interworking Architecture) [24], the QDFA (QoS-aware Data Forwarding Architecture) [25], and the IEA (Information Exchange Architecture) [26]. However, the proposed EP-DFS can't use the same procedure because it works with the P2P networks, which are not only combined mobile & wireless networks and IP based networks, but also applied the various SDN techniques in the synchronization process.…”

Recently, we usually use these words BEdge of Innovation^. It is caused by deployment of smartphone and various hand-held device including wearable devices. In most cases, the devices can easily communicate with other people or devices, and most of modern IT services are the converged services. These are very common phenomenon even in management of the disaster and safety fields. Generally, the emergency situations involve extreme situations such as a horrible congestion, bottleneck, some damaged infrastructure, and so on. Nonetheless, the infrastructure should support communications to the users in these situations. In this case, P2P communications and networking can be one of the best alternatives. In addition, if the P2P communications and networking method which is based on the device location can operate, it will be better solution than others. However, these solutions have been developing now, and the technology level is just a toddler stage, especially measuring indoor location. This is why we proposed the efficient peer-to-peer context awareness data forwarding scheme based on the devices location. The proposed P2P scheme has 2 operation modes. One is the normal mode, the other is the emergency mode. In normal mode, although the proposed P2P scheme is almost same as the existing P2P communication and networking scheme, the proposed P2P scheme is based on the synchronization between each peer when they need to communicate with other peers. In addition, the proposed P2P scheme dynamically assigns a bandwidth to users by the traffic types when the scheme is aware of P2P context. This is reason that it is a purpose to increase user throughput and to guarantee minimum user throughput. On the other hand, the propose P2P scheme will operate not only to find a best path, but also to transfer an emergency message, and the operation mode will automatically change to the emergency mode when the scheme is aware of the emergency situations based on P2P context awareness. Based on the proposed P2P scheme, the user can communicate with other people, and relay the message to outside in the emergency mode. To prove the excellence of proposed P2P scheme, we verified that the proposed P2P scheme outperforms than legacy scheme in various aspects, and we show these simulation results.
