Load balancing in wireless mesh networks (WMNs) is one of the major design goals for any routing protocol. In this paper, we propose AntMesh, an efficient data forwarding scheme, specifically designed for load balancing in multi-radio infrastructure WMNs. As the foundation of AntMesh, we use Ant Colony Optimization (ACO) in which artificial ants (agents) perform the routing and data forwarding to...
Wireless ad hoc networks using omni-directional antennas do not scale well due to interference between nearby nodes. Maintaining the QoS of the communications in this type of network is a difficult task. Using multiple narrow beam directional antennas alleviates this problem at the expense of connectivity. Multi-beam smart antennas allow the network topology to be adjusted dynamically by adjusting...
Wireless mesh network (WMN) has become a popular access network architecture. But because of its multi-hop nature, co-channel interference and contention, the attainable capacity of a wireless node in a WMN is significantly less than the radio capacity. We propose a overlay architecture for a WMN, where a wireless-ring (WRing) is deployed over the regular mesh for carrying wireless mesh traffic only...
In this paper, we propose an adaptive pacing scheme at the link layer for IEEE 802.11 based multihop wireless networks. Our objective is to improve the performance of higher layer protocols without any modifications to them. Our adaptive pacing scheme estimates the four-hop transmission delay in the network path without incurring any additional overheads, and accordingly paces the packets to reduce...
