Streaming in MANET: Proactive Link Protection and Receiver-Oriented Adaptation

Multimedia streaming applications can significantly boost the value of mobile ad hoc networks (MANET). Live streaming, however, means continuous data delivery, which is a major challenge in MANET. Because of host mobility, a streaming path may be broken easily, causing streaming interruption. In this paper, we address this problem with a light-weighted yet robust streaming protocol. Our technique distinguishes itself from existing ones with two innovative features: proactive link protection (PLP) and receiver-oriented adaptation (ROA). PLP allows a mobile host in a streaming path to find an alternative link before its current one becomes broken. This feature minimizes the chance of having to discover a new path in urgent to replace a broken link. While PLP protects the streaming continuity, ROA ensures the streaming efficiency by minimizing the hop number of a streaming path. Specifically, ROA dynamically adjusts the path of a live stream to make it as straight as possible along t...
