Schedule based MAC schemes do not perform well for dynamic network and traffic conditions. Their inflexibility makes them unsuitable for most real life applications. This inflexibility is due to the nature of schedule based approach. However, it depends mainly on the re-scheduling and slot allocation strategies employed. A flexible schedule based scheme should allow for the nodes to access the medium...
Literature indicates that spatial diversity can be utilized to compensate channel uncertainties such as multipath fading. Therefore, in this paper, spatial diversity is exploited for locating stationary and mobile objects in the indoor environment. First, space diversity technique is introduced for small scale motion and temporal variation compensation of received signal strength and it is demonstrated...
Multiple input multiple output (MIMO) offers significant advantages in terms of rate and reliability. We consider sharing the MIMO increased rate in wireless mesh networks (WMNs) links. Such sharing allows nodes in a WMN to concurrently meet more demanding communication requirements such as high data rates, increased transmission range, power savings and low dropping rates. In this paper, we propose...
Underwater sensor networks are typically distributed in nature and the nodes communicate using acoustic waves over a wireless medium. Such networks are characterized by long and variable propagation delays, intermittent connectivity, limited bandwidth and low bit rates. Due to the wireless mode of communication between the sensor nodes, a medium access control (MAC) protocol is required to coordinate...
