Mobile Data Collection in Wireless Sensor Networks Using Bounded Relay Hop
نویسنده
چکیده
Energy consumption becomes a primary concern in a Wireless Sensor Network. 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). Specifically, a subset of sensors will be selected as 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.

Mobile Data Collection Networks for Wireless Sensor Networks
Energy consumption is a major limitation of wireless sensor networks, with irreplaceable tiny sensors and multi-hop communication in sensor data aggregation as major contributors to this problem. While existing single hop data collection schemes reduce individual sensor energy consumption, they suffer from longer latency and low data delivery ratio. In face of these problems, we propose a mobil...

Energy consumption is a primary concern in the Wireless Sensor Network. This leads to pursue the maximum energy saving at sensor nodes, where a relay is used to transfer the data packet. This leads to the increase in the data gathering latency due to low moving velocity of the mobile collector. In this paper we study the tradeoff between energy saving and data gathering latency in mobile data g...

Most of the wireless sensor networks consist of static sensors, which can be deployed in a wide environment for monitoring applications. While transmitting the data from source to static sink, the amount of energy consumption of the sensor node is high. It results in reduced lifetime of the network. Some of the WSN architectures have been proposed based on Mobile Elements. There is large number...
