In this paper, we provide an overview of important transmission protocols for a certain class of challenged heterogeneous networks commonly termed delayor disruptiontolerant networks (DTN). We outline basic requirements and limitations for these protocols, including the Bundle Protocol and the LTP and Saratoga convergence layer protocols, sketch their respective solution approaches and provide ...

In this paper, we analyze coupled transmission lines and obtain a relationship between the moments of the coupled transfer functions. We then derive expressions for the first and second moments of the coupled transfer function which can be used to compute the response and threshold delays under various input excitations. We can compute the interconnectdelay under parasitic coupling effects by u...

WirelessHART networks are gaining ground as a real-time communication infrastructure in industrial wireless control systems. Because wireless communication is often susceptible to transmission failures in industrial environments, it is essential to account for failures in the delay analysis for realtime flows between sensors and actuators in process control. WirelessHART networks handle transmi...

Problem statement: As the Variable Bit Rate (VBR) is high in MPEG, the video experienced long delay and unexpected data loss. In wireless channel, due to noise and interference of other signals transmission rate cannot be predicted. Approach: In this paper we proposed an intelligent fuzzy logic controller for transmission of Moving Picture Expert Group (MPEG-4) video signals over wireless chann...

In an opportunistic network (OPPNET), the forwarding schemes for adhoc networks are not applicable since there is no complete path between the source and the destination node and relay nodes should store messages when no forwarding opportunity exists. Recently several proper schemes have been proposed in an OPPNET. Among them, floodingbased schemes result in very high network traffic and low tr...

In order to make the sensing data in the monitoring equipment’s sensor nodes reach to the monitoring center as soon as possible and deal with the equipment which has some problems, the network time delay should be guaranteed in the accessible Time Delay Bound. The paper mainly researches the transmission scheduling algorithm with the chain framework, which adopts the Token to do the transmissio...
