The pioneering work of Gupta and Kumar [1] has inspired many subsequent studies on asymptotically achievable per node throughput and delay analysis for wireless networks. In this paper, we evaluate the delay and maximum achievable per node throughput of a heterogeneous wireless mesh network (HWMN). We derive an analytical model which incorporates diffusion approximation method [2] and then compare...
Because of the instability of link quality, traditional network routing protocols, which are mainly based on the condition of "Best Path", can not work very well over wireless mesh networks. Forwarding packets along the "Best Path" may also induce load imbalance among nodes. This paper presents a novel routing protocol named HPRP (Hierarchical Probabilistic Routing Protocol) for...
Uniform random network (URN) is perhaps the most basic and generic model of complex networks. In a URN, each node links to exactly k other nodes which are randomly chosen from the entire network with equal probability. With such a simple topology assumption, URN is suitable for modeling homogeneous wireless mesh networks. However, compared to inhomogeneous networks like small world or power-law network,...
This paper presents a decentralised cross-layer dynamic power control (DDPC) scheme for wireless mesh networks (WMNs). A general cross-layer occupation measure (COM) based on transmission scheduling probability (TSP) and power control policy (PCP) model is proposed. Depending on the network traffic application and multiple transmission activity (MTA), each user adjusts its power dynamically so as...
The wireless link quality is time and space varying, depending on the environment and interference. In order to make efficient use of the scarce channel resource during topology formation, scheduling and routing, it is vital to understand the quality of the links in the wireless mesh network (in terms of e.g., probability of successful transmission or signal to noise ratio). The existing approaches...
Wireless mesh networks (WMNs) will play an important role in the next generation wireless communication systems because it can support broadband services with ubiquitous coverage by low transmission power. However, the question will be caused by using the shortest path routing protocol such as DSR and AODV in such multi-hop networks. Load unbalance of nodes will sharply degrade the traffic quality...
In this paper, we consider deployment of a wireless mesh network (WMN) to interconnect a video sensor network (VSN) and improve its energy efficiency. We propose a scheduling method for mesh nodes that performs fair scheduling if there is sufficient link capacity, and perform traffic grooming followed by scheduling using a novel constraint relaxation method if link capacity is insufficient. The resulting...
