摘要：Mobile ad hoc networks are infrastructure less multihop wireless networks. Topological changes in such a network frequently render routing paths unusable. Such recurrent path failures have detrimental effects on the network ability to support Quality of Service (QoS) driven services. A number of technology providers have implemented methods for multiplexing the data along with the compressed audio and video. These methods rely either on the allocation of data bandwidth as a constants bit rate (CBR) stream or the replacement of null packets in the MPEG stream with the data. Neither method is ideal for maintaining video quality and maximizing the efficiency of the transmission path. An efficient and promising technique for addressing this problem is to use multiple redundant paths between the source and destination pair Multipath routing algorithm allows building and use of multi paths for routing between the source and destination. if mobile hosts hold data items that are frequently requested by others, they have to transmit the data items many times and consume a large amount of power. In this paper, we discuss effective data transmission for not only maintaining data availability but also prolonging the lifetime of mobile hosts. Moreover, each mobile host collects multiple requests for data items and transmits the requested data items by multicast.
