Model Based Prioritized Bandwidth Estimation For Multimedia Application

A mobile adhoc network (MANET) consist a collection of mobile nodes that communicate in a multi-hop way without a fixed infrastructure. In wireless networks, the available bandwidth undergoes fast time-scale variations due to channel fading and error from physical obstacles. Estimation of available bandwidth in wireless network is a challenging task. Efficient management and sharing of bandwidth among the users becomes a key factor in enhancing system performance. Bandwidth allocation is a major problem in such multimedia and real time communications which drastically reduces the throughput of MANETs. To overcome this problem, an analytical model based bandwidth estimation algorithm is introduced for multimedia services over networks. In this method the available bandwidth is estimated based on the priority of the application and the number of access of these applications. Bandwidth for each node is enhanced to reflect the good packet delivery associated with lower control over head and lower packet delivery delay.
