Minimising energy consumption through mobility with connectivity preservation in sensor networks

Abstract

In typical mobile wireless sensor networks, flows sent from collecting sensors to a sink could traverse inefficient resource expensive paths and experience arbitrary delays. This is particularly problematic in event-based sensor network where flows are of great importance. In this paper, we are interested in energy-aware routing algorithms that explicitly take advantage of node mobility to improve energy consumption of computed paths. Mobility is a two-sword edge however. Moving a node may render the network disconnected and results in early termination of information delivery.To mitigate these problems, we propose a family of routing algorithm called Connectivity preservation Mobile routing protocols for actuator and sensor NETworks (CoMNet), that uses local information and modifies the network topology to support resource efficient transmissions. Our extensive simulations show that CoMNet has high energetic performance improvement compared to existing routing algorithms. More importantly, we show that CoMNet guarantees network connectivity and efficient resource consumption.

“…Wireless Sensor Networks (WSN) have become a part of modern everyday life since they can provide information such as temperature, humidity, presence and movement detection through one or many sensing modules (static or mobile wireless sensors) deployed over the area of interest. WSN have received a lot of attention over the last decade above all in improving the deployment quality [14,25], self-organization [11,31], energy efficiency [19], communication aspects [34,35], and the overall reliability and security [7].
