Even though channel assignment has been studied for years, most IEEE 802.11-based multi-hop wireless networks such as WSN, WMN, MANET are limited by channel interference. Properly assigning orthogonal channels to wireless links can improve the throughput of multi-hop network. To solve the dynamic channel assignment problem, a routing-based channel assignment algorithm R-CA is proposed. R-CA can allocate...
Multiple-Input Multiple-output (MIMO) has great potential for improving the throughput of Wireless mesh networks (WMNs). MIMO can increase network throughput via suppressing interference from neighboring links and/or allowing transmission of multiple independent data streams over MIMO antenna elements. However, these throughput gains are limited unless higher layer protocols also exploit these capacities...
The quality of wireless links is inherently dynamic, and this often makes the measurements of link delivery probabilities inaccurate over short timescales. We present Stable Opportunistic Routing (SOR), which improves unicast throughput for wireless mesh routing in the presence of inaccurate link-level measurements. In essence, SOR integrates two key features of prior approaches: (i) nodes trigger...
Significant throughput degradation of multihop path communication in wireless mesh network is one of the major problems in wireless communication. The main reason for the lack of bandwidth is channel interference, which is caused by contention for the shared channel between wireless nodes. The natural approach to overcome this problem is exploiting the availability of multiple channels multiple interfaces...
One of the most promising wireless technologies is Wireless Mesh Network (WMN). The aggregate capacity of wireless mesh networks can be improved significantly by providing each node with several Wireless Network Interface Cards (WNICs) and by using multiple channels in order to minimize the interference and to provide high performance in such networks. However, multiple WNICs in each node requires...
Wireless mesh networks (WMN) is one of the attractive wireless technologies which is expected to be the best alternative for the current wired broadband Internet access. WMNs use a completely wireless distribution system which can provide a good level of coverage, reliability and scalability. Multichannel Multi-radio nodes can be used in the WMNs to enhance the capacity of the network. However, due...
Cognitive radio networks offer the promise of adaptively allocating resources on the fly. In this paper, we describe an interference mitigation technique that relies on intelligent resource allocation across a mesh network. In previous work, we presented a method for improving the performance of wireless mesh networks (WMN) through the use of multichannel wormhole switching. An approximate 800-fold...
