High smartphone penetration and Average Revenue Per User (ARPU) growth imply a quick and good broadband services delivery. In this context, Mobile Networks Operators (MNOs) have to satisfy current subscribers and gain new ones. Small Cells (SCs) are a promising alternative to MNOs to reach emerging markets and meet the rising mobile broadband demand. However, most of those competitive markets have...
In mobile ad hoc networks (MANETs) where there exist multiple Internet gateways, performing load balancing among available gateways is vital in order to take full advantage of the network capacity and improve the performance. However, performing load balancing in a wireless environment is very challenging due to the inherently interfering and unreliable nature that characterize wireless communication...
Low-cost wireless routers are changing the way people connect to the Internet. They are also very cheap, albeit quite limited, Linux boxes. These attributes make them ideal candidates for wireless mesh routers. This paper presents a minimally invasive mechanism for redundant multipath routing in kernel-space to achieve high reliability with high throughput in a mesh network. This service is essential...
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...
