We envisage extending the coverage of existing terrestrial wireless broadband wireless networks to the sea so that cost-efficient wireless access is available to the ships near the shore. The coverage extension is achieved through a multi-hop WiMAX wireless mesh networks where ships, maritime beacons and buoys are the nodes. In such a multi-hop network, routing protocol plays an important role in...
We envisage extending radio coverage of the existing terrestrial wireless broadband networks to the sea to provide ships with cost-efficient high-speed connection to the Internet. This is achieved by forming a WiMAX based maritime wireless mesh network where ships are network nodes connected to the land station across multiple hops. In such a maritime wireless mesh network, time slot allocation is...
Multihop Relay (MR) is defined in IEEE 802.16J for coverage extension and capacity enhancement of the legacy IEEE 802.16e point-to-multi-point (PMP) networks. In MR networks, relay stations (RSs) deployment is crucial in achieving good network performance. In this paper, we explore the optimal RS selection problem. By incorporating highway mobility pattern and the Erceg terrain model, the RS selection...

During times of calamity, such as an earthquake or tsunami, rescue and recovery efforts are usually hampered by communications failure as the incumbent communications infrastructure has most likely been damaged or destroyed during the disaster. An ad-hoc communications infrastructure, with support for multimedia traffic such as Voice over IP and video- streaming, must be quickly put in place to support...
