Abstract:
Smart grid is an emerging technology that is of worth importance in efficient utilization of power. It is that communication and information technology that converts the typical grid systems into smarter one. There is a two way data flow between the supplier and the consumer that uses appropriate communication technology for that flow of information. So, this communication technology plays a pivotal role in these upgraded grid systems. In order to improve the performance of smart grids, one have select suitable network for communication and then optimize that network using different optimization techniques.
Wireless communication network is the best option for transference of information in smart grids due to their reliability, security, maturity, more coverage area as well as ease of deployment. Our focus is to optimize this selected cellular network to improve the overall performance of the network.
The main objective of this work is to find the best possible combination of user and BS (Base station) that in turn maximizes the overall throughput of the network for better efficiency of the network. There exists some conventional techniques for user and BS assignment which uses max-SINR rule. According to this techniques, the resources to each user are allocated on the basis of max-SINR which is not suitable for heterogenous network where pico/femto cells are deployed under macro BSs. Optimization of the network is done using heuristic as well as optimal algorithms. Heuristic approach always gives better results as compared to optimal results. Computational complexity is also decreased as compared to existing work.
