What is mobile sink in wireless sensor networks?

What is mobile sink in wireless sensor networks?

A sink is a fixed node or mobile node which is capable of connecting the sensor network to an existing communication infrastructure or the Internet. 6, 7. In conventional WSNs, data acquisition between sensor nodes and the sink is based on single-hop or multihop communication.

What is sink in WSN?

The wireless sensor network consists of small limited energy sensors which are connected to one or more sinks. The maximum energy consumption takes place in communicating the data from the nodes to the sink. Only those nodes are connected to a sink which makes the total energy of the sink less than the threshold.

What is static sink?

In the case of a static sink, nodes located in the vicinity of the sink deplete their energy (and die) much earlier compared to the nodes located farther away from the sink due to higher data relaying load.

What are the different types of mobility in WSN?

We can distinguish three different kinds of mobility in WSNs: (i) mobility of the sensor nodes; (ii) mobility of the sink node(s); and (iii) mobility of a monitored event/object.

What are sink nodes?

A sink node or a base station is basically a designated device similar to the normal sensor nodes but more powerful. The energy required to route a message to the sink node, for each and every sensor node depends on the distance from the sink node and number hops that message will have to travel.

What is also known as sink?

A sink – also known by other names including sinker, washbowl, hand basin, wash basin, and simply basin – is a bowl-shaped plumbing fixture used for washing hands, dishwashing, and other purposes.

What is data Muling?

Data Muling Approach for Long-Range Broadband Underwater Communications. Abstract: Autonomous Underwater Vehicles (AUVs) are widely used as a cost-effective mean to carry out underwater missions. During long-term missions, AUVs may collect large amounts of data that usually needs to be sent to shore.

Can sink node transmit data?

In the mobile sink scenario, a mobile sink follows the fixed trajectory, and the master node directly transmits the data. However, in a single sink scenario, all the sensor nodes transmit their data to their static sink via multihop communication.

What is Event mobility in WSN?

In this paper, we present an energy efficient and event driven mobility model (E3DM) where mobile sensors inform each other about a static event and adjust their route to reach to the nearest point of that event. Sensors exchange some useful information between themselves by packet transmissions.

What is node mobility?

Node mobility can be defined as hiding from the application. or user changes in the connection point to the Internet of. the terminal. Node mobility can be broken down into two. forms of mobility: wide area mobility and local mobility.

What is a sink used for?

A sink – also known by other names including sinker, washbowl, hand basin, wash basin, and simply basin – is a bowl-shaped plumbing fixture used for washing hands, dishwashing, and other purposes. Sinks have taps (faucets) that supply hot and cold water and may include a spray feature to be used for faster rinsing.

What is sink in algorithm?

A local sink is a node of a directed graph with no exiting edges, also called a terminal (Borowski and Borwein 1991, p. 401; left figure). A global sink (often simply called a sink) is a node in a directed graph which is reached by all directed edges (Harary 1994, p. Graph Theory. …
