Cross-Layer Protocols for Multimedia Communications Over Wireless Networks
In the last few years, the Internet throughput, usage and reliability have increased almost exponentially. The introduction of broadband wireless Mobile Ad hoc NETworks (MANETs) and cellular networks together with increased computational power have opened the door for a new breed of applications to be created, namely real-time multimedia applications. Delivering real-time multimedia traffic over a complex network like the Internet is a particularly challenging task since these applications have strict Quality-of-Service (QoS) requirements on bandwidth, delay, and delay jitter. Traditional Internet Protocol (IP)-based best effort service is not able to meet these stringent requirements. The time-varying nature of wireless channels and resource constrained wireless devices make the problem even more difficult.
