Information Processing and Routing in Wireless Sensor Networks

THIS BOOK PRESENTS STATE-OF-THE-ART CROSS-LAYER OPTIMIZATION TECHNIQUES FOR ENERGY-EFFICIENT INFORMATION PROCESSING AND ROUTING IN WIRELESS SENSOR NETWORKS. BESIDES PROVIDING A SURVEY ON THIS IMPORTANT RESEARCH AREA, THREE SPECIFIC TOPICS ARE DISCUSSED IN DETAIL - INFORMATION PROCESSING IN A COLLOCATED CLUSTER, INFORMATION TRANSPORT OVER A TREE SUBSTRATE, AND INFORMATION ROUTING FOR COMPUTATIONALLY INTENSIVE APPLICATIONS. THE BOOK COVERS SEVERAL IMPORTANT SYSTEM KNOBS FOR CROSS-LAYER OPTIMIZATION, INCLUDING VOLTAGE SCALING, RATE ADAPTATION, AND TUNABLE COMPRESSION. BY EXPLORING TRADEOFFS OF ENERGY VERSUS LATENCY AND COMPUTATION VERSUS COMMUNICATION USING THESE KNOBS, SIGNIFICANT ENERGY CONSERVATION IS ACHIEVED.
