Adaptive spectrum-based variable bit truncation of discrete cosine transform (DCT) for energy-efficient wireless multimedia comm
This paper presents a new adaptive scheme to reduce the computation energy of the discrete cosine transform (DCT) architecture for image/video coding. The scheme employs the noise ...

Performance of a Propagation Delay Tolerant ALOHA Protocol for Underwater Wireless Networks
We analyze a propagation delay tolerant ALOHA (PDT-ALOHA) protocol proposed recently for underwater networks [16]. In this scheme, guard-bands are introduced at each slot to reduc...
