This paper introduces a robust header compression method for mobile ad hoc networks. The node that implements this algorithm won't need to preserve header context while compressing or decompressing the header. When a packet loses or is corrupted, it will not impact following packets because of the independence of the successive compressed headers. This(More)
The Data Distribution Service for Real-time Systems(DDS) mainly describes how data is dealt with in a single node, but not the mode of data-exchange among nodes. The centralized label publication subscription mechanism is used for data-exchange in this article. In the wireless network, especially low speed wireless network of battlefield, it is important to(More)
In order to share information among all nodes, an all-to-all-broadcast scheme is needed for situation awareness networks. For this type of distributed sensor network, a directional antenna array, called multi-beam adaptive array (MBAA) is proposed to improve the transmission range and reject the interference. In this paper, an all-to-all-broadcast oriented(More)
As one of the important steps in the process of self-organization of wireless ad hoc networks, neighbor discovery has substantial influence on the network performance. Especially in the modern warfare environment, the time consumption of neighbor discovery is very important for holding the battlefield situation. In this paper, we address the problem of(More)
Networking Radar-Communication Integrated System (RCIS) promises an improved performance of radar and communication system platform by expanding scanning range and sharing information with each other. But equipping RCIS with directional antennas, in return, will worsen network's connectivity. In this paper, we aim to address the problem of neighbor(More)
In order to accelerate the information sharing, all-to-all broadcast needs more users to take part in the packet transmission at the same time. Directional antennas, which are capable of forming multiple beams, can provide improved spacial reuse on one hand. On the other hand, through analyzing the contention scenarios listed for multi-hop wireless networks(More)
Radar self-communication makes full use of the radar hardware resource and spectrum to fulfill the communication. As MIMO radar has become the new generation radar technology to be actively studied, MIMO radar self-communication and its capability are plausible to be investigated. The baseband models of MIMO radar and MIMO radar self-communication are set(More)
CICQ (Combined Input-Crosspoint Queued) switch fabric is an ideal solution for high-speed routers, which brings its nice distributed parallel scheduling property with no internal speedup required. Studying through resent scheduling algorithms for CICQ, it is shown that the basic reason leading to instability and performance decrease of throughput under(More)
