Efficient Mobile Data Collection with Mobile Collect

Abstract

The main task of most deployed wireless sensor networks is data collection. While a number of solutions have been designed for static networks, there are currently no widely used data collection algorithms for mobile sensor networks. In this paper, we concentrate on scenarios where many nodes, both data sources and sinks, move along a certain track in one direction, a scenario that is common in sports events. Rather than designing a new protocol from scratch, we extend an existing data collection protocol with lightweight mechanisms to make it efficient for mobility. Our extensive simulations and results in a testbed that includes mobile robots demonstrate that our solution is able to achieve high packet delivery rates at low energy consumption. For our target scenario, our solution more than doubles packet delivery rates when the network is sparse. Our solution also works well in scenarios with a higher degree of mobility where nodes move according to a more demanding random waypoint model.

“…Hassanzadeh in [19] concerns with the mobility of the sensor nodes as well as of the sink in a particular direction for improving the packet delivery ratio.…”

Building and Orchestrating Centralized Remote Management Procedures for Wireless Sensor Networks

“…The strengths of CTP are its ability to quickly discover and repair path inconsistencies and its adaptive beaconing, which reduces protocol overhead and allows for low radio duty cycles. Extended versions of CTP have been proposed to deal with the nodes' mobility [40]. Dozer [41] is a data retrieval protocol aimed at achieving extremely low energy consumption.…”
