Piconet and its capacity

A piconet is a small wireless network that consists of one master device and up to seven active slave devices. These devices communicate with each other using Bluetooth technology.

Parked nodes

In addition to the active slave devices, a piconet can also have parked nodes. These nodes are devices that are not actively participating in the communication but are still part of the network. When a device is parked, it is not using any of the network's resources, and it can be activated at a later time.

Capacity of parked nodes

According to the Bluetooth specification, a piconet can have up to 255 parked nodes. This means that a piconet can have a total of 256 devices, including the master and active slave devices.

Correct answer

Therefore, the correct answer to the question is option C, 255 parked nodes can be in the net.

Similar Computer Science Engineering (CSE) Doubts

Consider a simple graph with unit edge costs. Each node in the graph represents a router. Each node maintains a routing table indicating the next hop router to be used to relay a packet to its destination and the cost of the path to the destination through that router. Initially, the routing table is empty. The routing table is synchronously updated as follows. In each updation interval, three tasks are performed.i. A node determines whether its neighbours in the graph are accessible. If so, it sets the tentative cost to each accessibleneighbour as 1. Otherwise, the cost is set to .ii. From each accessible neighbour, it gets the costs to relay to other nodes via that neighbour (as the next hop).iii. Each node updates its routing table based on the information received in the previous two steps by choosing the minimum cost.For the graph given above, possible routing tables for various nodes after they have stabilized, are shown in the following options. Identify the correct table.
