Efficient peer-to-peer context awareness data forwarding scheme in emergency situations

Abstract

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.

A DPN (Delegated Proof of Node) Mechanism for Secure Data Transmission in IoT Services

“…However, the S-DTS utilizes a synchronization transmission scheme after the transmission start for providing an efficient data transmission. The concept of proposed S-DTS is fundamentally similar to the concept of S-DTA (Safe Data Transmission Architecture) [Kim and Na (2016)], EPC-DFS (Efficient Peer-to-Peer Context awareness Data Forwarding Scheme) [Kim and Suk (2016)], and ESD-DTS (Efficient Software Defined Data Transmission Scheme) [Kim and Kim (2018)]. Although the S-DTS will be also operates synchronization zones same as the Kim et al [Kim and Na (2016); Kim and Suk (2016); Kim and Kim (2018)], there are 3 different points mainly.…”

Efficient data delivery based on content-centric networking for Internet of Things applications

“…Most of current communication protocols in the IoT rely on point-to-point connections and are therefore vulnerable to link failures. Many improved solutions including p2p, 1 proxy-oriented, 2 and cloud-based 3,4 approaches were proposed and used with the current Internet, but they cannot resolve the single point of failure problem. We have also seen that the protocol incompatibility of today’s communication networks drives the IoT concept toward a bunch of sparse sensor networks.…”

Convergence P2P context awareness

“…As for the proposed learner activity model, it classifies learning activities in a CSCL system into three categories (vivacity, learning, and relationship) and then creates quotients to represent them accordingly. The paper, by Kim et al [2]., proposes the efficient peer-to-peer context awareness data forwarding scheme based on the devices location in emergency situations. This efficient P2P data forwarding scheme (EP-DFS) can be applied to various fields that are needed for P2P communications and networking.…”
