PUSH and PULL are two common data dissemination algorithms for data-centric sensor networks. The two algorithms work well with only a few sources or a few sinks, respectively; however, when there are many sources and many sinks, both of them become inefficient. In this paper, we propose a novel location-oblivious hybrid PUSH-PULL data diffusion (LOHD) algorithm, which suits a wide range of networks...
In wireless sensor networks, filters, which suppress data update reports within predefined error bounds, effectively reduce the traffic volume for continuous data collection. All prior filter designs, however, are stationary in the sense that each filter is attached to a specific sensor node and remains stationary over its lifetime. In this paper, we propose mobile filter, a novel design that explores...
In this paper, we study the maximum lifetime target coverage problem (MTC), which is to maximize the network lifetime while guaranteeing the complete coverage of all the targets. Many centralized algorithms have been proposed to solve this problem. A very few distributed versions have also been presented but none of them obtains a good approximation ratio. In this paper, we propose two O(log n) localized...
