— This paper considers two important issues for video sensor network, (1) timely delivery of captured video stream and (2) energy-efficient network design. Based on network calc...
— In large Wireless Sensor Networks (WSNs), each hop might incur varying delays due to medium access contention, transmission and computation delays. Fast and efficient query re...

We use a constrained optimization framework to derive fundamental scaling laws for both unstructured sensor networks (which use blind sequential search for querying) and structure...
Convergecast is a fundamental operation in wireless sensor networks. Existing convergecast solutions have focused on reducing latency and energy consumption. However, a good desig...
— In sensor networks, MAC protocols based on Time Division Multiple Access (TDMA) with wakeup and sleep periods have attracted considerable interest because of their low power co...
