48 Wireless Mesh Networks – Efficient Link Scheduling, Channel Assignment and Network Planning Strategies

Mesh routers in a WMN are stationary; therefore, the route selection should focus on discovering links that interfere with as few nodes as possible to provide high end-to-end

In contrast to traditional wireless networks, such as MANETs and WSNs, where nodes are

With the reduced cost of radios, MRs can be equipped with multiple radios. Hence, simultaneous transmission and reception can be achieved using intelligent channel

In MANETs, traffic can be from any peer Mobile Node (MN) to any other MN, while in

In MANETs, traffic distribution is generally assumed to be uniform, while in WMN, traffic

MANETs have been designed essentially for enabling communication within a small group of people, while WMNs aim to provide high-bandwidth broadband connections to a large community, and thus should be able to accommodate a large number of users accessing the Internet. Due to high estimated traffic volume in WMNs, scalability and fault tolerance

typically power-constrained, MRs have abundant power at their disposal.

throughput.

To the best of our knowledge, the proposed channel assignment algorithm is the first of its kind to use topology control based on power control for channel assignment in multi-radio multi-channel wireless mesh networks.

The main purpose of network topology control using power control is to minimize the interference between a MR and other MRs in the network by adjusting its transmission range using transmission power control. This leads to a better frequency reuse during channel assignment, which results in achieving the objective of significant improvement in the overall network throughput.
