A cross layer approach for controlling jitter in MANET based on bandwidth estimation

Jiter is referred as the variability of latency in packets over a period of time. In mobile network, topology changes rapidly which causes a reconfiguration of network. Therefore the latency of transmission also varies. It gives rise to a QOS problem as predicting exact latency is difficult. Hence time bound or real time packets can not be guaranteed highest QOS in MANET. It this paper we propose a unique mechanism of controlling jitter by bandwidth estimation and a cross layer approach. We establish a relationship between the available bandwidth and jitter and show that by appropriately measuring the bandwidth and accordingly routing the packets minimizes the jitter affect significantly.
