Network coding is a new paradigm that allows the intermediate nodes in a network to create new packets by combining the packets received on their incoming edges. The central problem in the design of network coding schemes is to assign local encoding coefficients for the intermediate edges in a way that allows every terminal node to decode the packets generated by the source node. The main applications...
Congestion mitigation and overflow avoidance are two of the major goals of the global routing stage. With a significant increase in the chip size and routing complexity,congestion and overflow have become critical issues in physical design automation. In this paper we present several routing algorithms for congestion reduction and overflow avoidance.Our methods are based on ripping up nets that go...
The index coding problem has attracted a considerable amount of attention in recent years. The problem is motivated by several applications in wireless networking and distributed computing, including wireless architectures that utilize network coding and opportunistic listening. In this paper, we propose efficient exact and heuristic solutions for this problem. Our numerical study shows that exact...
The advent of network coding presents promising opportunities in many areas of communication and networking. It has been recently shown that network coding technique can significantly increase the overall throughput of wireless networks by taking advantage of their broadcast nature. In wireless networks, each transmitted packet is broadcasted within a certain area and can be overheard by the neighboring...
This paper presents a simplified BLAST (Bell-Laboratories Layered Space Time Systems) architecture which is capable of achieving low BERs at very low SNRs thus resulting in high spectral efficiencies and higher data rates
