In this paper, we present UAV-aided Cross-Layer Routing Protocol (UCLR) that aims at improving the routing performance of a ground MANET network with aid from an Unmanned Aerial Vehicle (UAV). The UAV is added to a connected backbone formed by a collection of designated nodes in order to combat link failures and wireless link effects detected at PHY/MAC layers before the routing table adapts to the...
Wireless link effects impose unique challenges to routing protocols in Mobile Ad Hoc Networks (MANETs). In this paper, we propose Hybrid Cross-Layer Routing (HCLR) protocol designed and implemented based on the premise of being able to leverage a pair of proactive and reactive routing schemes. While the former is used to avoid long routing discovery latencies, the latter is used to compensate against...
Funded by a research contract from the Boeing Company, we report on the implementation of a Multiple-Input Multiple-Output (MIMO) software defined radio (SDR) platform forming an operational Mobile Ad-Hoc Networks (MANET) node. Our SDR platform utilizes Universal Software Radio Peripheral (USRP) including a motherboard for baseband processing, two daughter boards for RF frontend processing, and an...
With the advent of multimedia applications over wireless local area networks (WLANs), the IEEE 802.11e standard was proposed to incorporate quality of service (QoS) parameters in the medium access control (MAC) layer. It has been found through previous research work that the throughput of transport control protocol (TCP) is less when compared to that of User Datagram Protocol (UDP) in the IEEE 802...
