This deep space sensor network based on DTN is an important research in modern deep space communications technologies. Bundle layer plays a key role in the network. How Bundle layer can provide services for network more rationally and efficiently is an important influencing factor to improve and enhance the network performance. This paper proposes special network architecture for this DTN-based network...
In this paper, we propose WMRMTR (Wisdom Multi-path Routing Algorithm based on Maximum Transmission Reliability) algorithm. The calculation takes into account the probability of distribution of nodes and the paths delay in wisdom network. And then making the routing path to produce a set of routing which is, data packets can be parallel transmission. In the case of the mobile node, the packet transmission...
With the development of the network technology, PIM-SMv2 protocol acted as a feasible telecommunication technology, gains wide application and development. This paper discusses the performing principles of PIM-SMv2 protocol in detail, describes how PIM-SMv2 protocol building unidirectional share trees rooted at a Rendezvous Point per group. This paper presented the realization project of IPv6 multicast...
There are several different features of satellites network compared to ground networks, such as long time delay, large bandwidth delay production (BDP), high error rate, intermittent and asymmetric links, etc. There are abundant research results indicated that it will reduce its performance and waste precious network resource if apply the traditional TCP in the satellites network directly. Transfer...
Space network are now become a very important and necessary complementary to the ground networks, it will extend the terrestrial Internet networks to space. However, there are still many challenges exist before the space-ground integrated networks come true, and how to transport data reliably in space networks is the very difficult one among these challenges. TCP has been a robust and efficient transport...
The design and development of future ground-space integrated networks is one of the hot issues in space technology nowadays because of the long-link delay, high bit-error-rate, asymmetric bandwidth, intermittent links compare with the terrestrial networks. The focus of this paper is to design topology for this hybrid networks with space segments, select appropriate protocols for it and analyze its...
Based on the study of the characteristics of ZigBee technology and the analysis of the structure of wireless sensor networks, here proposed a new reliable, flexible and inexpensive remote lighting control system based on ZigBee technology and SoC (system-on-chip) solution. This paper emphasizes on the implementation of ZigBee protocol and data communication flow. The hardware and software design are...
