A Quadri-Stage Contention MAC Protocol with Opportunistic Network Coding Support for Underwater Aconistic network coding supported quadri-stage contention protocol (NC-QSCP), has been proposed. The QSCP employs a concentrated contention procedure to form a transmission schedule, according to which nodes can perform collision free channel access in the following dedicated transmission stage.

Fast Encryption of JPEG 2000 Images in Wireless Multimedia Sensor Networks,The algorithm selectively encrypts the lookup table of probability model in MQ coding. As the size of lookup table is fixed and only such one table is used for an image, the proposed algorithm is fairly efficient and thus can perform fast encryption on large volume of JPEG 2000 images in WMSN.

ActiviTune: A Multi-stage System for Activity Recognition of Passive Entities from Ambient FM-Radion the signal propagation path. Activities in the proximity of a receiver can thus induce a characteristic pattern on amplitude-based features. We investigate the use of the radio frequency channel to detect activities. ActiviTune, our passive device-free recognition system, implements a multi-stage
