A MANET is a self-configuring ad hoc network that could be very useful for battlefield communication. Because of its versatility, Tactical Mobile Ad-hoc NETwork (MANET) is also widely used by modern military units especially for the autonomous maneuvering of unmanned vehicles and robots. But Quality of Service in Tactical-MANET is difficult because the network topology changes dynamically. The resource...
This paper proposes silence drop first algorithm(SDF) for the active buffer management. This algorithm finds and drops silence packet rather than talkspurt packet in the queue for resolving buffer overflow of queue. This algorithm can serve more simultaneous user while maintain voice service quality with same link capacity. Simulations with voice codec of G.711 and G.729a are performed in this paper...
In tactical environment, MANET (Mobile Ad Hoc Network) has the network characteristics which make highly dynamic nodes, self-organized in fully-distributed style. Also, it has a harsh wireless channel environment compared to the commercial networks. In these channel environments, optimal path decision suited for Quality of Service (QoS) of transmitted tactical traffics must be performed by recognizing...
