Algorithm Part 1 (for 20 Marks):
- The available Device to Device (D2D) pairs should be sharded (cluster) based on the
application, Public Safety and Commercial Applications. For Sharding, any clustering
algorithm can be considered. - A shard may contain any number of D2D Pairs.
- Each shard should have at least one Cellular User (CU).
- Display the shard members.
Figure 1. Sharding Example
Algorithm Part 2 (for 20 Marks):
Based on the shardes created in Part 1, carry out the communication considering the following
points. - Assume there are N D2D pairs (D2DN
) in a shard where N ranges from 1 ,…., N.
(assume public safety shard for the experiment). The D2D pairs start communication in
regular intervals i.e, the D2D1 pair starts data transfer at 2 second, the D2D2 pair starts
data transfer at 3 second, the D2D3 pair starts data transfer at 4 seconds etc.

Sample Solution
According to the Center for Disease Control and Prevenation (CDC) (2015), Autism Spectrum Disorder (ASD) is a developmental disability that causes deficits in social communication/language, social interaction and skills, and behavioral challenges. The Diagnostic Statistic Manual-5 (DSM-5) provides criteria for ASD with specific deficits and actions in three categories: communication, restricted ideas and repetitive behaviors, and social interaction (American Psychiatric Association, 2013). The symptoms must be present in early childhood, which is eight years old or younger, and the symptoms together have to restrict and impair every day functioning for a child to be diagnosed with ASD (American Psychiatric Association, 2013). It is a spectrum disorder because there is a wide range of skills and different symptoms an individual with ASD can have (NIH: Autism Spectrum Disorder, 2015). The severity of the disorder also varies, so some individuals need more services than others, and different levels of treatment are used in the interventions based upon the individual (NIH: Autism Spectrum Disorder, 2015.) There are many different interventions and teaching procedures used to aid a child to learn and to progress developmentally. Incidental teaching is a method in which the child and adult interact in a natural environment that is not structured, such as free play, where the adult will teach a skill based on the child’s interests (Hart & Risley, 1975). It is a method in which children learn labeling and language in a naturally occurring setting (Hart &Risley, 1975). Incidental teaching is child-selected since the child initiates the interaction based on a request for help from the adult (Hart & Risley, 1975). The request can be either verbal or non verbal, and if the adult chooses so, he/she can partake in incidental teaching and decide the cue and what language behavior the goal is to be obtained, and the steps if the child responds to the cue, or if the child does not respond to it (Hart & Risley, 1975). Incidental teaching is a>
