We propose a protocol to construct a degree-bounded delay sensitive overlay multicast tree called MODE (Minimum-delay Overlay tree construction by DEcentralized operation). MODE aims at maintaining or shortening the maximum end-to-end delay of the tree at fluctuation of mobile nodes' delay in a decentralized way.

We also propose a new middleware, which supports implementation and evaluation of Application Layer Multicast (ALM in short) protocols in real environments. The middleware provides many functions by which it can largely reduce the time and effort required for ALM protocol prototyping, performance evaluation and tuning. By using those functionalities, we have easily implemented several well-known application layer protocols and successfully performed their performance comparison in real environments. As an example, we have implemented ALMI, NARADA, NICE and OMNI as ALM protocols, and compared their performance on PlanetLab.
