Auction-Based Data Gathering Scheme for Wireless Sensor Networks Abstract This letter proposes a novel data gathering scheme for wireless sensor networks (WSNs) that limits the energy expenditure, and hence, prolongs network lifetime. Data gathering is modeled as an auctionwhere a node broadcasts its own result only if it is higher than the maximum already-broadcasted result by other nodes. For a WSN of 100 nodes, the mathematical and simulation results […]

Comments Off on Low-Cost Localization for Multihop Heterogeneous Wireless Sensor Networks
Posted in: IEEE 2017, NS2
Low-Cost Localization for Multihop Heterogeneous Wireless Sensor Networks Abstract In this paper, we propose a novel low-cost localization algorithm tailored for multihop heterogeneouswireless sensor networks (HWSNs) where nodes’ transmission capabilities are different. This characteristic, if not taken into account when designing the localization algorithm, may severely hinder its accuracy. Assuming different nodes’ transmission capabilities, we develop two different approaches to derive the expected hop progress […]
