Ever since the internet took off as a data network for sending email and browsing websites. The option of putting voice traffic on to the net has been in consideration ever since internet was able to transmit media. This is otherwise called Voice over Internet Protocol (VoIP). VoIP is implemented in Mobile Adhoc Networks (MANET) but its range is considerably small. This leads to congestion and improper Quality of Service (QoS). Current implementation of VoIP over MANET has issues like hidden and exposed terminal problems. In order for MANET to expand its connectivity, there should be at least one node within its range. As the range of MANET is a disadvantage, distant connectivity is an issue. In this paper, a method has been proposed to use mobile Wireless – Fidelity (Wi-Fi) hotspot instead of MANET for VoIP. For this, mobile nodes are connected within a range of a hotspot network (100 ft.) for audio transmission. This scenario would be simulated using both mobile hotspot and MANET and the results are compared for better understanding. Main aspects like efficient data transmission, QoS and security are taken into account.
