Abstract The new generation telecommunications is growing at a spectacular pace and Device-to-Device (D2D) communication networks plays major role to meet the growing demands by billions of connected devices over the globe. Generally, indoor based D2D communication networks relays on distributed small cell solutions for better connectivity. This research proposes Signal-toInterference-plus-Noise Ratio (SINR) based – Device Association Vector Algorithm (S-DAVA) for maximum network connectivity by efficiently discovering the neighbors and its D2D link based on network sum rate and SINR. The algorithm uses Rician model for Line-of-Sight (LoS) component to investigate the D2D network performance. The algorithm when evaluated with other conventional methods showed an improvement of 18.85% in throughput, and 10% of efficiency in energy with reduced network delay of 19%. This paper also checks its performance over traffic load, outage probability and network sum rate. Keywords Connectivity . Device-to-device communication . Indoor environment . Network delay . SINR .

1 Introduction The demands for wireless access is continuously increasing and a huge amount of data is circulating over today’s wireless networks, leading to increase in volume of wireless traffic. Device-to-Device (D2D) communication is one solution to this huge demand as it improves spectral efficiency and minimizes load on backbone network [1]. D2D communication network has found its application in commercial, public-safety purposes and most of context-aware applications. It involves detecting and communicating with close by devices enabling physical-proximity communications [2]. As a result, in recent years, the potentiality of D2D communications to enhance spectral usage is being encouraged [3]. Unlicensed band D2D technologies includes Bluetooth and WiFi-direct, but their functionality was limited because of manual pairing * Sreedevi A. G. [email protected] T. Rama Rao [email protected] 1

and short-range coverage. According to diverse studies, D2D communications promise less delay and consumed energy in single-hop communications and better network coverage in multi-hop communications. Additional performance parameters in single and multi-hop D2D communications constitute higher data-rate, Quality-of-Service (QoS), spectrum-efficiency, network capacity, service availability and stabilized network load [4]. D2D communication is being foreknown as an essential fragment of the emerging fifth generation (5G) networks, as 5G systems feats intelligence at t
