We propose an admission control method at edge nodes. This method aims at maximizing network throughput and calculates an input traffic limitation ratio at each edge node, which is used for admission control. Since the proposed method only uses input traffic volume information, it does not need to take into account the traffic matrix among edge nodes. Therefore, this method can be easily applied to...
The increasing viability of three dimensional (3D) silicon integration technology has opened new opportunities for chip architecture innovations. One direction is in the extension of two-dimensional (2D) mesh-based tiled chip-multiprocessor architectures into three dimensions. In this paper, we focus on efficient routing algorithms for such 3D mesh networks. As in the case of 2D mesh networks, throughput...
Along with the reactive routing algorithms of mobile ad hoc network (MANET), preemptive routing is a patch method which tries to warn the source node and to tell it to change route in time before a link is about to break Preemptive method was proposed to decrease packet losses and improve TCP performance in MANET. However, the precision of warning occasion is an important problem, and affects TCP...
In this paper, we present a fully decentralized algorithm for fair resource sharing between multiple bag-of-tasks applications in a grid environment. This algorithm is inspired from related work on multi-path routing in communication network. An interesting feature of this algorithm is that it allows the choice of wide variety of fairness criteria and achieves both optimal path selection and flow...
Energy management is the key issue in the design and operation of wireless network applications like sensor networks, pervasive computing and ubiquitous computing where the network is primarily driven by battery-powered embedded devices. This paper studies network coding as an energy minimization technique. Network coding reduces the energy consumption by minimizing the number of transmissions required...
We consider multicast network codes that allow to tradeoff throughput against cost. We construct a single code that enables the source to control the throughput, always achieving the minimum possible cost per transmitted symbol. Nodes in the network perform linear coding operations that are the same for all achievable throughput-cost pairs. On each of their outgoing edges nodes transmit either symbols...
In this paper, we investigate an important issue for real-time multimedia over multi-hop ad-hoc networks on different layers. Such application requires receiver playback buffers to smooth network delay variation and reconstruct the periodic nature of the transmitted packets. Packets arriving after their schedule deadline are considered late and are not played out. This requires that the network is...
