Data dissemination of emergency messages in mobile multi-sink wireless sensor networks

Abstract

In wireless sensor networks (WSNs), data dissemination is generally performed from sensor nodes to a static sink. If the data under consideration is an emergency message such as a fire alarm, it must be transmitted as fast and reliably as possible towards the sink of WSN. In such mission critical applications, it may not be enough to have one static sink but there will be multiple and mobile sinks. Sinks can be associated to first responders such as firefighters, but also to unmanned aerial vehicles (UAVs). The existing approaches have a high communication cost and a high delivery latency, which makes them less suitable for emergency situations. As an alternative to existing protocols, we present Honeycomb Architecture and Hexagonal Tiling-Based Data Dissemination (HexDD) protocol for emergency message transmission in mobile multi-sink WSNs. Simulation results show that HexDD has a high data delivery ratio and a very low data delivery latency, which are major requirements for disaster management scenarios.

Routing and Clustering of Sensor Nodes in the Honeycomb Architecture

“…Erman et al proposed in [30,31] the algorithms of the nodes association with the cells in the honeycomb architecture and the addressing system of these cells; we use the same algorithms for each honeycomb cluster to assign the nodes to the cells and to get their addresses. e cell addressing system is used in the routing operation inside the honeycomb clusters; it is on the form of [i, j] in every honeycomb cluster, with i the index of the cell rings and j the index of the cell in the ring i with j 0, 1, 2, .…”

Dynamic Path Planning Design for Mobile Sink with Burst Traffic in a Region of WSN

“…Hot spot strategy has been proved to be an effective method for data collection so far, and it needs grouped nodes gather their information on hot spots for mobile sinks' visit in sequence [4,5]. Many studies on algorithms about hot spot locating [4,[6][7][8][9][10] and mobile sinks trail predesigning [11][12][13][14][15][16][17][18][19][20][21] have been reported.…”

“…In literature [14], the HexDD (Honeycomb Architecture and Hexagonal Tiling-Based Data Dissemination) protocol was proposed for the emergent data transmission in wireless sensor network, which partitioned network into independent hexagonal meshes and then stored the emergent data on nodes of hexagonal grid boundary. The mobile sink moved randomly to collect the emergent data from the boundary nodes by sending query packets.…”

Cooperation among Wirelessly Connected Static and Mobile Sensor Nodes for Surveillance Applications

“…In a large sense this work is closely related to ours and an idea that is shared in both is the combined use of ground sensors and UAVs taking part in the same sensor network and cooperating to achieve surveillance mission goals. In [ 16 ] a rendezvous-based data dissemination protocol to deliver critical alarm messages issued by the static sensor nodes to the mobile ones in the context of AWARE project is presented. This approach divides the network of static sensors in a set of hexagonal cells, like a honeycomb, which is a solution used in other applications such as cellular phones.…”
