Abstract
Voiceover Internet Protocol (VoIP) application is a vital technology that is quickly growing in the Mobile Ad hoc NETwork (MANET). Packet loss is a factor that can significantly affect the Quality of Service (QoS) for VoIP performance. Due to the dynamic nature of MANET, it is a challenging task to maintain the desired packet loss rate. This paper aims to enhance the performance of VoIP in the MANET using a fuzzy logic model. The input for the model is VoIP packet loss and the outputs are the optimal parameters of MANET (node number, pause time, maximum speed, and maximum connection).Network Simulator (NS2) was used to perform all simulations. MATLAB was used to implement the proposed fuzzy model. Moreover, the performance of the model was evaluated using NS2, and the results show that our proposed fuzzy model offers a significant enhancement in terms of the VoIP packet loss rate (P.LR).
Highlights
Voice over Internet Protocol (VoIP) is one of the fastest rising Internet applications in recent years[1].It replaces the old Public Switched TelephoneNetwork (PSTN) with a converged network where data, voice, and video packets are carried together using a single IP-based network
The results show that the proposed Fuzzy logic based traffic differentiation technique reaches improved delivery performance over the existing traffic differentiation scheme for DTNs
The membership function consists of five fuzzy sets (Very low (VL), Low (L), Just High (JH), High (H), and Very High (VH))
Summary
Voice over Internet Protocol (VoIP) is one of the fastest rising Internet applications in recent years[1].It replaces the old Public Switched Telephone. Networks were designed to provide services to non-real-time applications such as FTP, HTTP, and email services which can tolerate some delay, jitter, and packet loss. They are not sensitive to low network performance. Real-Time Transport Protocol (RTP) to transfer voice packets over IP based networks. None of them has employed the VoIP packet loss rate as input for the fuzzy system. The contribution of this paper is to build a new fuzzy logic system that considers packet loss rate as the input. The input for the model is VoIP packet loss rate and outputs are MANET parameters (number of nodes numbers, maximum speed, maximum connection, and pause time).
