Bluetooth Network

$(10$ Marks$)$

The following question is dealing with evaluating the efficiency of Bluetooth network.

A star Bluetooth network is composed of $7$slaves and a master. A synchronous communication mode is considered where the effective bit rate is $430Kbps.$ Assume that the token size is $100$ bits and the data size is $1480$ bits

$1-$ Determine the time efficiency of the network if only four slaves are sending data

$2-$ What will be the time efficiency of the network if the data size is $720$ bits only?

$3-$ Compare the two efficiencies and conclude about the effect of data size

$4-$ The master is having two slaves only. The first one is having a voice channel, the second is having an asynchronous data traffic

a$)$ The voice traffic is $64kbps,$ each Bluetooth time slot supports $240$bits, what is the time gap between two voice slots?

p$)$ What is the maximum bitrate allowed to the second slave?

$-)$ Sketch the time diagram of the flow between the master and its two slaves

Energy saving

Marks$)$

For the Wireles Sensor Network given in the figure bellow, the number on each link indicates the consumed ener yy of propagating a packet over this link and the numbers in parentheses below the nodes indicate the nodes' remaining energy capacity. find the following $($with all required details$)$:

a$)$ Minimum hop route

b$)$ Minimum $-$ energy consumed per packet route

c$)$ Maximun $($average$)-$ energy capacity route
