A Packet Loss Salvation Scheme for Voice over MANET

This paper experiments a hybrid of mobile ad hoc wireless network (MANET) and fixed land network. We analyze the issues of transferring voice over such networks, and provide a packet loss salvation scheme to reduce packet loss rate. We also provide a new estimation mechanism by utilizing information gleaned from the upstream intermediate node. We take jitter into consideration and analyze how jitter exerts its influence. According to this packet transmission metrics decisions could be made on whether or not a packet should be transmitted at a particular time. Our protocol algorithm was implemented on ad hoc on-demand distance vector (AODV) routing protocol. From our simulation results and analysis it is shown that our scheme can reduce packet loss rate in voice over MANET compared to that of the original AODV
