Network coding has been proved as an effective way to enhance the throughput of the multihop wireless ad hoc networks in both unicast and multicast traffics. However, in a random network topology with non-coding-aware routing protocols, the performance enhancement may be limited because the packet routing scheme does not take advantage of the possibility of network coding. In this paper, we propose...
In this paper we analyze performance of network coding focusing on two specific network coding schemes: XOR and random linear network coding. We have simulated different topologies and traffic patterns in order to provide better understanding of network coding behavior and its possible bottlenecks. As a part of our performance evaluation we address computational complexity of coding and decoding operations...
We consider wireless networks in which multiple paths are available between each source and destination. We allow each source to split traffic among all of its available paths, and ask the question: how do we attain the lowest possible number of transmissions per unit time to support a given traffic matrix? Traffic bound in opposite directions over two wireless hops can utilize the "reverse carpooling''...
In wireless networks, transmissions can generally be overheard by unintended nodes in the vicinity of the sender and receiver, potentially causing interference to their own communications. Much of the related research has considered this as a nuisance and resulted in various proposals for overcoming the interference using scheduling, channel assignment, and many other mechanisms. In recent years,...
Recent research has proven that network coding has great potential to improve network throughput in wireless networks. To fully exploit the performance gain brought by network coding, coding-aware routing has been studied to proactively change route of flows for creating more coding opportunities. However, in today's multi-rate wireless networks, coding may not be a wise decision as the lowest rate...
