Investigating voice communication over multipath wireless mobile ad hoc network

Abstract

With the rapid growth and popularity of wireless LANs (WLANs), a demand of Voice over IP (VoIP) is also increasing. In recent years, dominant trend of development in Mobile Ad hoc Networks (MANET) technology makes VoIP services more appealing. However, it is still quite challenging to ensure quality voice communication in MANET. Some of these challenges include packet loss due to network congestion, and variable packet latency. Not only traditional single-path ad-hoc routing but also traditional voice codec fails to perform well under these conditions. In this paper, we depict a framework for VoIP over multipath multihop wireless network, in which we propose multipath ad-hoc routing and traffic allocation approach.
