Tree-based routing structures are widely used to gather data in wireless sensor networks. Along with tree structures, in-network aggregation is adopted to reduce transmissions, to save energy and to prolong the network lifetime. Most existing works that focus on the lifetime optimization for data aggregation do not take the link quality into consideration. In this paper, we study the problem of Maximizing...
The advent of participatory sensing markets and spectrum markets based on the wireless networks have led to a new kind of auction dealing with spatially reusable items, which can be shared by multiple parties that are geographically far apart enough from each other. Simply applying traditional auctions to spatially reusable items is vulnerable to bid manipulation, and may lead to low allocation efficiency...
