Abstract
Device-to-Device communication (D2D) process are used in 5G cellular network. D2D
allows communication between two devices, without participation of the Base station or the
evolved NodeB (eNB). In 5G cellular networks, with D2D communication enabled within is
considered as two-tire networks. These two tire networks are referred to as macro-cell tire and
device tire. The two-tier network needs to be designed with smart interference management
strategies and appropriate resource allocation schemes. In two-tire network architecture
cellular users and D2D users share common Resource Blocks (RBs). Such paradigms allow
potential increase in the number of supported users but it increase the cost of interference.
Because of this we need to design an efficient interference management system. Interference
can be reduced by appropriate resource allocation and power control. We propose a two steps
approach. In the first step we concerns with the efficient RB allocation to the users. The
second one is the transmission power allocation. . We discuss about a minimum interference
resource allocation algorithm based on the TDMA method and power control scheme. Firstly
peer has to detect, then select the best mode (D2D or Cellular) depends on the distance. Two
peer discover technique are used, one is fully dependent on the base station network and
another is semi dependent on the network. We present an optimized mode selection process
.For D2D users and cellular users resource are allocated, depends on the path gain. We
proposed a minimum interference algorithm to allocate resource. In order to control power
three power control scheme has been used. Hence in terms of increased number of users,
interference reduction and power minimization can be done efficiently. After simulation using
MATLAB we analysis the developed algorithm. We see that D2D communication is fast and
efficient if we able to mitigate interference.
