Wireless Mac Protocols for Real-time Battlefield Communications

Addressing the problem of timely packet transmission in a wireless soft real-time system such as one would nd on the battleeeld, we present ve splitting protocols that take packet deadlines into account. Three are blocked access and two are free access algorithms. Mathematical models of the algorithms are developed, and compared with simulations. We show, as expected, that the blocked access al...

Channel Adaptive Real-Time MAC Protocols for a Two-Level Heterogeneous Wireless Network

Wireless technology is becoming an attractive mode of communication for real-time applications in typical settings such as in an industrial setup because of the tremendous advantages it is capable of offering. However, the high bit error rate characteristics of wireless channel due to conditions like attenuation, noise, fading and interference seriously impact the timeliness and guarantees that...

Wireless Sensor Networks: MAC Protocols and Real Time Applications

Wireless Sensor Networks(WSNs) detect events using one or more sensors, then collect data from detected events using these sensors. This data is aggregated and forwarded to a base station(sink) through wireless communication to provide the required operations. Different kinds of MAC and routing protocols need to be designed for WSN in order to guarantee data delivery from the source nodes to th...

Multimedia transmission with adaptive QoS based on real-time protocols

In this paper, we describe a mechanism for adaptive transmission of multimedia data, which is based on real-time protocols. The proposed mechanism can be used for unicast or multicast transmission of multimedia data over heterogeneous networks, like the Internet, and has the capability to adapt the transmission of the multimedia data to network changes. In addition, the implemented mechanism us...
