Bluetooth suits for diverse computing and communication devices and becomes a built-in feature in millions of products. One of important problems for Bluetooth nodes is to become aware of their neighbors. Since the process is time consuming it is critical to compute the neighbor discovery timeouts. Therefore the mean and variance of the device discovery time is analyzed considering different magnitude...
In this paper we discuss about 3 general issues on mesh topology in “networks on chip” (NOC): Utilizing multi-level mesh for delay reduction, using route by considering the mesh topology concept, and finally an optimal model of mesh topology named “multi-level mesh topology” which is defined based on 5-layer network model is suggested. In multi-level mesh topology we can see that this architecture...
Wireless sensor networks have prominent feature and promising future, while limited hardware resource and constrained energy pose huge challenge for protocols researcher. This paper proposes a dynamic cross-layer and energy-efficient communication protocol DCLE for wireless sensor networks. In DCLE, a synchronization scheme that features global schedule and stagger sleep is proposed to achieve sleep...
Supporting random access of a large number of devices in a short time period is an enormous challenge in machine-to-machine (M2M) communications. In this paper, we propose a dynamic allocation scheme of random access channel (RACH) resource for clustered machine-to-machine (M2M) communications, in which delay-sensitive devices coexist with delay-tolerant ones. Since delay-sensitive devices share random...
Satellites give exceptional points of interest, for example, remote scope with fast sending, separation lack of care, transmission capacity on interest, safety to physical debacles, and offering broadband connections. TCP has been produced for wired systems that have a lower delay and a low piece mistake rate. It is the most usually utilized transport layer convention as a part of the Internet and...
Ship damage control is an important measure to maintain ship vitality when suffering damages. Through the study of a single node command ship damage control disposal process, this article established a model of ship damage control command based on T-Petri; On the basis of analyzing of typical damage by the crew compartment fire scene processing based on T-Petri damage control model, and optimizing...
Current network architecture suffers overloading due to extensive resource utility. This paper proposes a resource mapping algorithm upon service layer of service-based network: the unit of service component requests resource as well as limits; an agent is embedded in the component to surveil the utility of network resource. If network resource violates the limits, agent will punish the component...
The use of scheduling algorithm in virtual channel multiplexing in CCSDS AOS affects the channel utilization of AOS space communication system. According to the traffic characteristics in AOS, the system model is established by using stochastic network calculus and Fractal Brown Motion (FBM) model which takes consideration into the self-similar characteristics of traffic. According to the characteristics...
