Abstract: Due to increasing number of users in mobile cellular networks, demands of networks have been growing around the global and also due to larger number network distributors and deployment of more mobile cellular networks, the demands of capacity, coverage and cost are increasing. The major problem with having more networks within small area networks is interference between networks and coverage. These problems are more in urban areas due to its densely populated areas and connectivity issues. In recent technologies, the heterogeneous and homogeneous wireless cellular networks have become dominant networks for minimization of problems said above. To address these issues, Modified Homogeneous Cellular Network (MHCN) and Heterogeneous Cellular Network (HTCN) are designed, evaluated and compared in terms of throughput, network coverage and capacity of networks for different ranges and between various nodes. The both networks use Femtocells and these cells are deployed around 30 with 6 base stations (BS). The combination of MHCN and HTCN are known as Multi-Hop Heteroheneous Cellular Network and it consists of femtocells place irregular within specified area for low power BS to have a communications between mobile nodes and BS through single or multi hops. Initially the coverage and capacity are investigated by using downlink MHCN’s and under the situation of Rayleigh fading channels, an capacity expression is derived by splitting the cell into femto and macro cells for the first time. Later on the effect of the density and transmitter power and also SINR are analyzed on the capacity by MHCN and the scenario is analyzed for the same cells under conditions of infrastructure area and Ad-HoC area which are direct and through hops communications. Finally, simulated results in NS3 and numerical values are conducted and validated to various data packets.
