As the wireless network scales up in size and complexity, the need to study the scalability and behaviors of these networks and their protocols becomes essential. Opportunistic routing utilizes broadcast nature of wireless network, and significantly increases the unicast throughput. However, all of the current opportunistic routing protocols have to rely on the whole topology information. This indeed...
In this paper we develop a unified theoretical framework for estimating various transmission costs of packet forwarding in wireless networks. Our framework can be applied to the three routing paradigms, best path routing, opportunistic routing, and stateless routing, to which nearly all existing routing protocols belong. We illustrate how packet forwarding under each paradigm can be modeled as random...
In this paper, we propose a novel routing metric, namely biased delivery probability (BDP), for measuring the wireless node's capacity of forwarding data packet to the destination. BDP essentially assigns different weights to the multi-paths information associated with different hop counts. An theoretical theory is established to compute the weights for different scenarios. Using BDP routing metric,...
Opportunistic routing is a new design trend of wireless routing, which can dramatically improve the end-to-end throughput over traditional routing by judiciously utilizing the broadcasting nature of wireless network. However, the global scheduling scheme it adopts restricts its application in large-scale wireless network, due to the big waste of the end-to-end transmission latency and the computation...
How to efficiently use the spectrum resource to provide quality-of-service (QoS) support is a challenging task for wireless communication systems. In this paper, a resource reservation-based on-demand spectrum assignment and routing protocol is proposed to provide QoS support for IEEE 802.11-based multiradio multi-channel ad-hoc networks. Our work distinguishes from prior ones in that we don't treat...
