Delay-Tolerant Networks (Fall (2003)), also called disruption tolerant networks (DTNs), represent a fairly new networking paradigm that allows inter-connection between devices that current networking technology cannot provide. There are a wide variety of networks where an end-to-end connection between a given source and destination may never be present. Consequently, traditional routing protoco...

In a distributed hard real time system communication between tasks on different processor must occur in bounded time. The inevitable communication delay (termed the end-to-end delay) is composed from the delay in transmitting a message on the communications media, and also from the delay in delivering the data to the destination task. This paper gives schedulability analysis bounding the media ...

In a distributed hard real-time system, communications between tasks on different processors must occur in bounded time. The inevitable communication delay is composed of both the delay in transmitting a message on the communications media, and also the delay in delivering the data to the destination task. This paper derives schedulability analysis bounding the media access delay and the delive...

According to the problem of the intermittent connectivity of the nodes in the delay-tolerant sensor network, considering that the nodes in the network are of social selfishness, we study how to reduce transmission delay and communication overhead on the basis of ensuring the message delivery success rate of the entire network. We present a delay-tolerant routing algorithm based on the node self...

Recently, underwater Wireless Sensor Networks (UWSNs) attracted the interest of many researchers and the past three decades have held the rapid progress of underwater acoustic communication. One of the major problems in UWSNs is how to transfer data from the mobile node to the base stations and choosing the optimized route for data transmission. Secure routing in UWSNs is necessary for packet d...

We propose an efficient communication protocol for multimedia data delivery in high-speed multichannel networks. Multimedia traffic is generally categorized into two types: real-time traffic and delayable traffic. High-speed multichannel networks refer to the third-generation computer networks, e.g., WDMA networks, with high-speed parallel multichannels to be able to support multiaccess communi...
