Mobile Data Collection in Wireless Sensor Networks Using Bounded Relay Hop

Abstract

Wireless sensor networks are used for ambient data collection in diverse environments where Energy consumption becomes a primary concern. Wireless sensor network (WSN) requires robust and energy efficient communication protocols to minimize the energy consumption as much as possible. We propose a polling-based mobile gathering approach and formulate it into an optimization problem, named bounded relay hop mobile data gathering (BRH-MDG).Centralized and Decentralized algorithm for selecting polling points that buffer locally aggregated data and upload the data to the mobile collector when it arrives. We analyze the trade-off between energy saving and data gathering latency in mobile data gathering by exploring a balance between the relay hop count of local data aggregation and the moving tour length of the mobile collector. The proposed approach shortens the data gathering latency compared with the other schemes.
