A MAC Layer Abstraction for Heterogeneous Carrier Grade Mesh Networks
نویسندگان
چکیده
Providing carrier grade services to a large number of mobile users is becoming an important challenge for wireless network operators. One promising solution for offering cost-efficient alternatives compared to classical cellular approaches is the use of wireless mesh networks along with the use of heterogeneous radio technologies. In this paper we propose a MAC abstraction layer to lessen the management burden of heterogeneous radio technologies. This abstraction layer is intended to hide the complexity and specifics of different wireless interfaces, this way supporting the use of a single set of routing and capacity handling mechanisms.

متن کاملTowards QoS Provisioning in a Heterogeneous Carrier-Grade Wireless Mesh Access Networks Using Unidirectional Overlay Cells
The visibility and success of Wireless Mesh Network (WMN) deployments has raised interest among commercial operators in this technology. Compared to traditional operator access networks WMNs have the potential to offer easier deployment and flexible self-reconfiguration at lower costs. A WMN-type architecture considered as an alternative for an operator access network must meet similar requirem...
متن کاملImproving Performance for CSMA/CA Based Wireless Networks
Carrier Sense Multiple Access with Collision Avoidance (CSMA/CA) based wireless networks are becoming increasingly ubiquitous. With the aim of supporting rich multimedia applications such as high-definition television (HDTV, 20Mbps) and DVD (9.8Mbps), one of the technology trends is towards increasingly higher bandwidth. Some recent IEEE 802.11n proposals seek to provide PHY rates of up to 600 ...

متن کاملEnhancing Efficiency and Effectiveness of 802.11 MAC in Wireless Mesh Networks
The 802.11 MAC protocol is widely used in wireless mesh networks. However, with multi-hop transmissions prevalent in such networks, neither the current 802.11 DCF basic scheme nor the RTS/CTS scheme can achieve full utilization of network capacity for various reasons. First, the 802.11 MAC provides low spatial reuse (low parallelism of transmissions). Second, the collision avoidance mechanism i...
